Parts Schematic
The MBA-1 and MBA-2 Buttstocks require the use of an A2 Rifle buffer tube. Use the diagram below to determine if you currently have an A2 buffer tube. If you have a Carbine buffer tube you may want to look at the MBA-3, MBA-4 or MBA-5 buttstock. If you are ordering an MBA buttstock kit, the proper buffer tube is included.

The differences between an A2 Rifle Buffer Tube and a Carbine Buffer Tube.

All MBA Buttstocks are Sling Swivel Ready.

This means that the buttstocks have molded pockets that accept Grovtec Sling Swivel Cups for use with Quick Detach swivels. The Sling Swivels and cups are NOT included with the buttstocks and must be ordered separately. This is to keep the cost of the MBA buttstocks down. Not every customer needs sling swivels and including them would raise the price of the buttstocks. The sling swivels are available separately. See the videos below for installation instructions using the install kit, or using a 1/4″ Allen wrench.

  1. Denns Misal

    Excellent product. Better than expected, already put on my varmint ar 204 ruger. Hope to get to range soon to test out. Looks like will be great.

  2. John Bennett

    A very good product at a good price. I was a bit concerned that the locking mechanism on the rear of the stock might not be strong enough to hold up under recoil. I set the adjustment to it longest extension and placed a substantial amount of weight against it trying to see if it would slip. It held up perfectly. The stock has a lot of adjustment, is light, and strong at a price point most people can afford.

  3. Brian Takaba

    Finally a better option than a PRS. The MBA is Extremely light, completely adjustable, more adjustment range than a PRS and a lot less cost. Simply the best stock for an AR I have ever used! Plus you got to admit, Its the coolest looking as well. LOVE IT! Two thumbs up! Awesome job LUTHAR

  4. Bill Brotherton

    I own TEAL BLUE BRAVO LLC. I was recently ask to build an AR 15 for a highly decorated army medic. The gun will be presented to him at a small gathering where he will be the guest of honor. I chose the MBA STOCK. These are the best stocks out there . If you want a well made stock that is fully adjustable. This is a get down to business stock.

  5. Dianna Liedorff

    Love the weight and adjustability of the buttstock. The only thing is is lacking from the PRS is the setup for the rear pod, something that was rarely used anyhow. Would definitely use this over the PRS, especially at this price! Will be outfitting many other rifles with an MBA in the future.

  6. DHS Dan

    Best fully adjustable stock on the market for under $150. This stock is great in every aspect! It has a solid lightweight design and is fully adjustable while maintaining its ridgidity! The only thing I would like to see done is add a lower rail for a monopod. Can’t wait to see what else Randy has in store for the future! Ps: if you ever need any field testing, I’m your man!

  7. N/A

    The MBA is a great butt stock. It is easy to adjust and the range of adjustment is more than enough. Plus it is ambidextrous! And the price is very reasonable. Can’t wait to try it out on my varmint rifle. Thanks, Luth-Ar. for making a fantastic product.

  8. Joe

    Better than the magpul PRS and a lot less expensive. Really good product.

  9. Jared L

    Sweet stock! Awesome design, very new-age and simple to use. Very impressed with how light it is. Thanks for delivering a great product!

  10. Tim Thomas

    MBA VS PRS: Currently run 2 Magpul PRS. Thought id give this one a try. BOTH have their advantages and dis advantages.

    Price – the MBA comes out $75 less than the PRS
    Weight – the MBA is deffinately lighter than the PRS
    Strength – The mba isnt as “SOLID” as the PRS but it wasnt surprising due to the weight advantage
    Options – was surprised the MBA came ready for a QD sling mount, but it was not included.

    All in all by the time you buy the QD mount, your still saving $$ over the PRS, Weight is less than the PRS, but you give up a slight bit of strength with the MBA.

    Both have their places and i will continue to use each in their own setting !!

  11. Bill Sahlberg

    I just received my very 1st order of LUTH-AR MBA’s and was impressed from the ease of ordering, prompt shipping, and the ease of installing using these simple instructions. More than all this, is the snug fit, the great feel, its solidness, and ease of adjustability that makes the fit perfect to my cheek weld.

    My customers will see the quality of these and it will be an easy switch away from what they are thinking they want to one of these less expensive and better built MBA stocks.

    I have also own several very personalized AR15s and AR10s and I will be trading these out in the near future for the much more Superior LUTH-AR MBA.

  12. N/A

    Great product, offers something the others do not have, which is lateral adjustment of the cheek piece to get good eye relief for your scope and provide clearance from the charging handle and all the other stuff in that area. The only thing keeping me from giving it a 5 star rating is that I wished there were QD mounts available as an option. Good price, great product, and it is a weight saver; what more can you ask for.

  13. Josh

    Great Deal. I’ve been wanting a buttstock with a cheek weld for some time now. I was eyeballing one from another vendor and it was just too much to spend. I’m glad I held out. The MBA is awesome. It looks great, fits to the lower receiver perfectly, adjusts easily, and is really comfortable. It is just what I needed.

  14. David

    Fantastic. First owned a Magpul PRS for $255. Then I found the MBA and figured for a $120 less I would give it a whirl. Turns out its the better buy. Well made product easy to use, looks awesome, and functions flawlessly. I like the feel better than the PRS. It functions easier than the PRS. I found the PRS controls stiff. I also like how the MBA is not quite as bulky and heavy. Would buy again. I hope more products come out from Luth-AR id love to see and use them. I hope they come out with a rail system I would love to be one of the first to try it out.

  15. JOHN @ KNAPP’S CUSTOM RIFLES ROUNDUP MT.

    Great. MBA and MBA 2 are the stock of choice for me and my customers. They are easy to install and adjust for a ^’5” guy or a 5’2′ gal.

  16. N/A

    3 gunner. Shot my new stock in match yesterday and loved it.
    I really like being able to dial the stock in to fit me. Planning on getting one for my other gun.

  17. Bret Parker

    Blue Ridge Mountain 3 Gun Championship. Randy Luth donated the stocks to the prize table. For those who don’t know Randy is a long time supporter of the shooting sports.

  18. Steve

    So cool. I love this but stock I cant say enough good things about it all my shooting buddy’s are pretty jealous already just wish it came in tan but o well keep it up you have a wonderful product and shipping was really fast

  19. George Martian

    The MBA is the bomb! I have been looking at all the butt stocks available for a few months and none come close to the MBA. I got to shoot an AR-10 with one and that sold me. I’m 6’4″ with long arms and the adjustability is the best I have found. And the light weight is a plus as well. Get one, you won’t be sorry!

  20. Matt

    A Great Stock at an Even Better Price. Finding a stock for a precision rifle build with adjustable LOP and comb can be challenging to say the least. Your only real, readily available option until now has been Magpul. But if you’re like me and building on a budget, LuthAR has probably really caught your eye. I ordered one not really expecting too much but was thoroughly impressed on its arrival.

    Construction is solid, adjustments are easy and secure. My one gripe is that the cheek piece is a little flexible and can give a little bit if you really tend to lay on the rifle. I don’t see this as a problem, just a fact because of the way it’s manufactured. Installed on my rifle the stock is both good looking and very comfortable in use. Overall I gave it 5 stars because the quality to price ratio is very high and it’s just an all around good stock. I would buy the stock again and recommend it to people looking for a high quality adjustable stock.

  21. George Cahill

    I am so pleased with this stock…solid, inflexible, adjustable and very light weight…lighter than the M****l PRS stock and a much better return on investment! Can’t say enough about this product and how customizable it is. It might not improve your groups but it will make it much easier and more comfortable to attain your best without shelling-out an arm & a leg. Randy Luth has designed a winner!

  22. Richard

    It is a solid product and delivers as advertised for precision. I was surprised at the weight. It was heavier than I thought it would be. I won’t return it because of that feature. The adjustments are solid and exact. Overall, I’m very happy with the craftsmanship and quality of the stock. To keep with the precision idea, I would like to see a spot to put a monopod

  23. N/A

    Awesome buttstock! Great looking item, easy to install, great adjust-ability, and light weight! only complaint is the check riser. It will rise more but the plastic piece catches the top of the buffer tube mount. Not an issue and does not hurt the stock. Don’t get me wrong, this is a strong design and looking forward to running it through its paces!

  24. Alex

    Rock solid, light, looks great, easy to install

  25. N/A

    Echo of past review. This is a precision stock so it should have an attachment for a monopod. I use an accu-shot monopod so producing a stud mount would suffice to mount a stud-mount monopod. The best would be a rail built into the toe of the stock though…

  26. P. McCarty

    A nice light adjustable AR stock. Not overly complicated and easy to use and install. Nice and light. Seems plenty sturdy for the task at hand. Flush cups are easily installed giving the stock quick attack sling swivel hook-up. I like this product.

  27. Joe W.

    Very nice. This was easy to install and adjust for left handed use. I am looking forward to getting some range time with it to get the final adjustments made.

  28. Mike Dixon

    Good value for your bucks. The stock is just what I expected. Not complitcated to install with an excellent fit right out of the box.

  29. Ofishel GunWorks LLC

    Just installed and it looks really good. Better quality than i expected. Fits great and is pretty adjustable. Have had good comments from customers so far. I cannot wait to test on my range. I am a gunsmith and hard to please so thumbs up guys..

  30. Sean

    Solid and well made. Was skeptical of quality given the price. Item shipped quickly, was extremely pleased with Quality, Fit, and Finish. Very rigid and comfortable. Cheek weld is solid, smooth, with NO WHISKER CATCHERS.

  31. Jim C

    A match for the PRS @ 1/2 the PRICE! I have built several custom rifles with Magpul PRS stocks and this is as good for a better price and reduced weight. I’m a customer for sure.

  32. Brian Urias

    This Was AN Awesome Product!! Looks Better In Person AndFeels Better Than I Expected! WantThis On All MyGuns!!

  33. Rollin Shatto

    Beautiful quality. The nicest and most comfortable Butt stock I have ever had. It’s on my 3-Gun AR and would recommend this to anyone for there AR.

  34. N/A

    Impressive to say the least. Love it. It has taken all the abuse I’m dished out.

  35. Jeremy

    Quality built stock, with very affordable price. I purchased the Luth-AR MBA for a .308/7.62 that I’m in the process of building. I wanted to keep the rifle as light and maneuverable as possible but also have some adjustability in the stock. The quality of the MBA is outstanding and the price is more than affordable. They have put a lot of time and engineering into this stock. I’m excited to complete the build and try it out!

  36. N/A

    Great product for a fraction of the price competition is charging! From the shipping time, to the packaging to the installation instructions. ….absolutely spot on!! Fit perfectly and in less than 5 minutes I was readying for the range!!!

    Best part … it was a fraction of the price the competition charges.

    Thank you

  37. N/A

    Great set up. Pictures don’t tell the whole story here is is one well engineered AR stock!!! Mates function w/ lite weight, & good looks!!

  38. Michael Stack

    Love it. When I saw this stock on the Armalite 3 gun AR I had to get one. I like the ability to custom fit this stock to my shooting style. I have not had an opportunity to run it through some real 3 gun stages yet. But I like the fit and finish of this product and am looking fwd to banging out some major matches with it.

  39. Bill

    Outstanding Product at Great Price. This stock is built great, and very lite. I would put this stock up against similar ones on the market and this is just as good if not better. The best thing its a fraction of the cost of its competitors. Easy to install and adjust.

  40. Martin Barber

    Attention Grabbing Awesomeness. This stock functions perfectly. Grabs attention instantly. Pure genius

  41. N/A

    Love this stock! Took under 10 minutes to add to rifle and it extremely light weight and durable!

  42. Matthew

    I bought this stock to replace the A2 stock on my Rock River a4 varmint. The build quality is excellent. It is very easy to install and adjust. This stock would be great for people who are into long range and short range shooting.

  43. livingintx

    I just installed the MBA-1 with the .308 RIFLE BUFFER TUBE ASSEMBLY KIT on a Bushmaster 308 ORC. Love this product! Had no issues with installation and the rifle functions great!

  44. n3480h

    We bought an MBA-1 and an MBA-3 for my rifle and my son’s carbine. Delivery was incredibly fast. Both of these units are top quality, tough as nails, and the range of adjustment is excellent. Completely satisfied on all counts – and a much better price than that “other” brand. The coyotes are going to hate these rifles.

  45. Robert Hall

    We use this stock in our AR-10 builds and have had nothing BUT excellent results out of it. Every customer has loved it, and NEVER had any issues out of them.
