Most Helpful Positive Review Exactly what I was expecting
I wanted a buttstock with a pic rail on it... and there are very few options available. This is perhaps the only one in current production, and almost certainly the only one available in FDE. Why would anyone need a buttstock with a rail? Well, if you get a nice Anker USB battery for your thermal o...

Most Helpful Negative Review Fab defense not so fab
The butt stock itself was alright. It looked pretty cool in a steroidal tactical way. Almost futuristic. The cheek riser, however, was useless. even more, it was detrimental to the operation of my rifle. While implementing the Cheek riser the charging handle could not be pulled all the way back unle...

Cheap junk and CRAPPY customer support

by WCR1nova, Verified Owner from NM, United States Written on March 25, 2026
I bought this because of being inexpensive. I should have bought MagPul. The cheek riser kept slipping when I tightened the knob hand tight, and would not easily fall down unless I tightened the knobs to almost the breaking point. I emailed customer service and they said "Ther’s no “friction locks” or anything like that. just tighten the knobs". Clearly they have care for customer service. I called and tried to talk to them and was insulted with what's the problem if you are able to tighten it down. Good news to fix the issue take a soldier iron and melt small grooves on the track. It now only needs to be hand tight to stay in place.
Pros:
  • Price
Cons:
  • customer service
Best Used for:
  • Larping
Would recommend: No

Great butt stock

by BT, Verified Owner from WI, United States Written on January 21, 2026
I put this Fab Defense butt stock on all my builds. Good snug fit, no slop and play. The riser is useful and puts my head in the correct position for shooting. The battery storage in the stock is also a plus. Pricey, but worth the extra $$$.
Pros:
  • Built well
Cons:
  • Pricey
Best Used for:
  • Completing AR builds
Would recommend: Yes
