SLR Gas Block

by johnchip, Verified Owner from CT, United States Written on April 16, 2025
SLR tii the rescue. Gas was leaking out one of my uppers that has Rosco barrel whixh was causing cycling issues. I replaced it with this SLR gaa block and problem solved. The tolerances are tighter than the one that used to be on it. This is a high quality GB and j an very happy i got it. Worrh every Penn and can as definitely recommend.

good gas block

by Bri, from OR, United States Written on April 23, 2023
The SLR GAS BLOCK. I love all SLR items as well as this one. I do like the adjustment slr gas block better. Being able to turn the gas up or down save on your ar parts. If you need a gas block and do t have the money to get the adjustable one get this one
