TRIARC Systems Easy Pin Gas Block for AR15 and AR10 Barrels


In stock

The TRIARC Easy Pin Gas Block’s design aids it to be quickly pinned to your barrel. The pre-cut hole means there is no wasted time by drilling through the gas block. This pre-cut hole is positioned low enough, so only the necessary amount of material from your barrel is removed to ensure a “bombproof” installation. Since there is less material to remove, pinning the barrel is easier to accomplish with a standard hand drill or drill press. We always recommend that a competent gunsmith do the installation. However, because of the gas block’s design, it is much easier for the individual builder to accomplish the pinning of the gas block without catastrophic damage to the barrel or gas block.
