Most Helpful Positive Review Great Stock
I’m running this on a 450 Bushmaster and the difference is beyond words. If you are running anything more than 223 you need this buffered stock. Look fit and finish are all very high end. Before the stock I could shoot 4-5 rounds of 450 now I can shoot all I can afford!
Most Helpful Negative Review False advertising but decent stock
-1st off, I received this "recoil reducing" stock today and found zero indicators that prove this stock helps eliminate recoil. This item receives 1 star for selling under false pretenses. *someone please challenge me on how this stock reduces recoil in anyway* -aside from false advertising, not a...

Great for the price, and bonus

by Woody, Verified Owner from TX, United States Written on February 9, 2025
Nice rubber pad, intuitive adjustment, and moderately snug fit. For the price a great stock. But including the shock absorbing feature and it a a no brainer. Works well, but even better after a dry powder lube is added to the buff tube.
Pros:
  • Looks great
  • Good fit
  • Easy instal
  • qd
  • Great quaility
  • Small storage space
  • rubber pad is grippy
  • shock absorb works well
Cons:
  • None
Best Used for:
  • Everyone
  • 300 AAC Blackout

Good upgrade

by Woody, Verified Owner from TX, United States Written on February 3, 2025
From a standard plastic stock to this was a very nice upgrade. Since it was the same or considerably less than comparable stocks, it seemed like a good choice. The added shock absorbing feature seemed like a bonus that probably wouldn't effect anything, at least not negatively. I pleasantly experienced a very slight less sharp pulse (say 10-15%) with subs, but a more noticeable difference with supers (say, 15-20%). As with physics, the energy didn't evaporate into the ether of the universe, but seem to just be averaged out at just a usable amount. In a rapid fire use it will help keep you on target, and in a competition scenario or just a long day on the range it seems like it would reduce fatigue. Needs a little moly powder or thin film of drylube on the outside of the buffer tube to work best, otherwise the friction will slightly inhibit smooth action. The storage will be nice once I figure out what to keep in it
Pros:
  • Good deal
  • extra feature for same price
Cons:
  • None
