Most Helpful Positive Review AR Buttstock
I recently had shoulder reconstruction surgery. I needed a buttstock that would help absorb the kick from my AR. This item came as a recommendation from a local Pro Shop Expert in my area. Once I attached it and took my AR out to the range I immediately felt the difference from my stock buttstock...

Most Helpful Negative Review came with wrong parts, now have to wait forever for a refund
It’s supposed to come with commercial and mil-speck shims. Mine was missing the mil-speck. Now I have to wait the week for shipping and who knows how long for processing.

FAB Impact stock

by Glenn Chamberlin, Verified Owner from NH, United States Written on March 19, 2026
The aesthetics of this stock are amazing in my opinion. Looks amazing on my custom rifle build. It’s sturdy, lightweight and functions as advertised. The only knock I have on it is that the Mil-spec adapter fits a little loose on my mil-spec buffer tube giving it a bit of unwanted rattle.

Clean Install and Quality Build

by Brendyn, Verified Owner from CA, United States Written on March 17, 2026
I've been on the hunt for something other than the run-of-the-mill Stock - there are some pretty fancy expensive ones out there and then there's some basic ones too. This stock fit the bill perfectly - not supremely expensive but with a unique look that I absolutely loved. I didn't even care about the spring for recoil reduction until I had it in hand and tested it out - what an innovative idea - can't wait to test it out in live fire conditions.

10/10 so far.
Pros:
  • install easily
  • Good construction and design
  • Pricing is good
Cons:
  • limited colors available
Best Used for:
  • Tactical & every day & outdoors

Used Parts

by Polished Brass, Verified Owner from TN, United States Written on November 14, 2025
The part appears to be used. The direction statements that the stock has mil-spec shims preinstalled, but the commercial shims were installed. The edges are worn from use. Utilizing my 20 years experience in Quality Control, I made the edges call from the edges that can't be worn from banging inside in the box from shipping.

Very good it does reduce recoil in my ar15

by Tom, Verified Owner from NY, United States Written on November 3, 2025
My AR already had little recoil due to tuned gas and SRS buffer, muzzle brake. With this stock my AR recoils lighter like a gas blowback BB gun… amazing, almost feel like a fake gun. Only issue if you have to let me pick is the little play after installed. I have mil spec tube and I changed to mil spec inserts but still there’s a little play. Perhaps that’s what’s accepting the recoil and using the springs to dampen it. Once you cheek weld it tho you don’t feel any play no more. So it’s good. Very good. Price is reasonable. Looks good too.

life saver

by magnum, Verified Owner from ID, United States Written on October 26, 2025
Sighted in my AR10 and literally had a bruised shoulder afterwards bought the FAB Defense stock and just got done shooting 70 rounds and there was no problems literally twice as many rounds down range than before. I also had shoulder surgery last year and there is not soreness from the recoil either. Left it on the medium setting I might adjust it to see if it will even get better.

Nice stock

by Frank, Verified Owner from MA, United States Written on October 5, 2025
Looks really good. Haven’t shot it yet but there is a slight wobble. Could be my buffer tube. Will try on different tubes. Good upgrade though.

Great buttstock

by Groundedmoose, Verified Owner from TX, United States Written on October 3, 2025
Use to use Magpul buttock, this one helps to reduce recoil. Like how you can interchange the size between Mil and Commercial. Changed the size to mil and reduce the loose feel. Also, feels customized for me.
Pros:
  • Good feel
  • custom fit
Cons:
  • None
Would recommend: Yes
