Most Helpful Positive Review fab defense impact reducing stock!
This is a great functional stock and looks super pleasing on the eyes as well. The price might seem steep but it’s completely worth it, there are two sets of inserts for commercial and mil spec tubes. They do wonders, slap the stock on my Ak and boom no wiggle no movement it’s solid. Next is the imp...

Most Helpful Negative Review Cheek Piece unacceptable
This stock is built solid, even too heavy for its size but adequate. The problem is the Cheek Piece which only tilts up at an angle. Unlike the Core CP model which slides up and down evenly and with much more adjustable distance. Conversely, the core impact has a huge cheek piece but is basically un...

looks good but gimmicky

by Stephen Thatcher, Verified Owner from TN, United States Written on April 6, 2026
I really wanted this to work. The check rest is way too high at lowest setting for any scope set up in my shop. Really awkward adjustments

Chuck Norris himself could not move the shock absorber to the next setting. Good luck!

Impressed until I wasn't

by Anonymous, Verified Owner from OH, United States Written on March 2, 2026
Researched this stock for a while before purchasing. Impressed with shock absorption technology and adjustability from Mil Spec to Commercial Buffer tubes. Once I got it the Commercial shims were installed ( opposite of what was described) I tried it due to my firearm was known to come with one or the other Buffer tube depending on production dates. Stock fit very sloppy so I tried swapping the provided shims. Extremely stiff retention tabs that broke when removing them so now it can never be used for a Commercial spec tube. After installing the Mil spec shims the stock was still loose....mainly from the adjustable locking lever and not the tube itself. For a stock crowding $100 i was not impressed with the fitment. The stock itself is made well but fitment is sketchy.
Pros:
  • Shock absorption
Cons:
  • poor fitment
  • Provided shim broke upon removal
Would recommend: No

but mine has 1 big issue

by Cb, Verified Owner from IN, United States Written on February 13, 2026
I assume it works well if a good unit, BUT mine came with a severely warped interior. Unable to use. Box also came ripped and with wrong inserts. Contacted OP no response. If i get no response, gona have to sand it down myself. Unacceptable. Should be great after that. Spring unit works well. Cheek rest easy to adjust or remove if necessary
Pros:
  • Spring unit seems like it works well. Sturdy. Good buttpad
Cons:
  • Got a faulty unit. Warped interior.
Would recommend: Yes

Good Fit and solid.

by Bouchardoil66, Verified Owner from FL, United States Written on February 1, 2026
Installed this on an AR10 and it works well. It also looks great and the adjustable cheek rest is a nice add on when shooting from a prone position. Solid build and adjustable recoil spring helps to take up some recoil.
Would recommend: Yes

Get the impact stock w/o the cheek riser

by Moose, Verified Owner from IN, United States Written on July 31, 2025
I love these impact stocks. But! Get the impact stock w/o the cheek riser, I own both and I prefer it without. It lifts your head too high to look down a scope, thankfully it clips on and off. If you want this stock, buy the impact stock without the cheek riser ($69.99) and buy the cheek riser separately for (18.99). Save yourself $20-$40.

Construction good, functionality not great

by Lok, Verified Owner from CA, United States Written on June 23, 2025
The construction of this buttstock is as good as any other out there, very good quality, built to last.
The spring is rather strong, I have not had time to test it on the range, however I am of skeptical the claims that it will significantly reduce recoil because of the stiffness of the spring and length of travel.
The main point I want to make is the overly large and high cheek weld attachment renders the shooters head out of position to look down the scope.
I have this set up on an AR with EOTECH red dot and Vortex 3x Mini Magnifier.
With this stock installed replacing a standard Magpul stock, I found it impossible to look through the Magnifier because my head is out of alignment due to the cheek weld.
I ended up removing the cheek weld which defeats the aesthetics
Pros:
  • Looks great
Cons:
  • Can look through scope, head is displaced too far
Best Used for:
  • Iron sights perhaps?
Would recommend: Yes
