5 Karve-P used as a finger stop. Fits perfectly!
Posted by Jay on May 20th 2020
9” handguard on a 7.5” barrel, this little guy gets the job done perfectly. Tied in with the RailScales 2 slot mini dot and now I don’t get burned. I was pleasantly surprised with the quality of product....

Simple addition to a weapon that makes a big difference. Arrived quickly, went on easy, and works great. Highly recommend for SBRs and sub guns.

Looks great, doesn’t feel cheap. Awesome guys at rail scales that called to make sure I had the colors right because I had two different colors in cart.

3 Karve-P Sent with to small of a bolt
Posted by Kyle kidder on May 4th 2020
The bolt that was sent with my handstop was too short and couldnt even screw on the mlock nut. I had to use an bolt and nut from a previous handstop. Other than that its a very nice product.
