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.

incredible product

by Cody, Verified Owner from AZ, United States Written on August 27, 2026
This stock is absolutely amazing for special projects. Standard ARs produce minimal recoil. I have built one in 277 fury with this stock making it lighter than a 556. This stock also softens a 458 recoil immensely. This product is a diamond in the rough
Pros:
  • Softer recoil
  • Smooooooth action
Cons:
  • None
Best Used for:
  • Large caliber builds
Would recommend: Yes

Springy sproingy silly stock

by Hagiya, Verified Owner from NV, United States Written on July 18, 2026
I really like this thing! Have it set to Medium with my DDM4V7 and it does exactly as it says on the tin, though it's not like 5.56 has much recoil.

Admittedly it's a bit more expensive than a "regular" stock, but the way I see it, this thing does actually improve recoil impulse without negatively affecting anything.

The shade of my OD Green is SLIGHLTY more vibrant than my Magpul furniture but it's close enough where it's not very noticeable.

There's a slight wobble/rattle but not a significant amount; I'm sure I can use tape on the buffer tube to eliminate it entirely if I cared enough.

The "suspension" gimmick is very fun to mess around with, as you can physically push it down to test the effects in action. Plus the dark red is a nice accent color without being gaudy or trashy.

Overall? I like it! I might get another one for my CA3; I imagine this will be far more noticeable on something like a .308, but as many other reviews have stated, I imagine this is a godsend to people that have shoulder issues.
Pros:
  • Excellent comfort
  • Actually improves recoil impulse
  • Unique aesthetic
  • Built-in QD sling socket
  • Great traction on buttpad
  • Extremely easy to install
Cons:
  • Price I guess?
  • Slightly loose on buffer tube
Would recommend: Yes

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
Would recommend: Yes

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.
