Adjustable gas blocks are great for competition shooters. With the turn of a couple screws you can turn an ultra-reliable yet hard recoiling rifle into a veritable pussycat, allowing you to get back on target faster after each shot. While it’s a great feature, retro-fitting existing guns to have an adjustable gas block is a bit of a pain. For those who have run headlong into this problem, Rubber City Armory has a solution . . .
Instead of cutting off the gas at the gas port, RCA decided to ut the adjustment at the other end of the gas system. It makes adding this feature to your gun a breeze, and makes adjustign the gas system just as easy. Instead of needing to take the handguards off to get at those adjustment screws, you can just remove your bolt carrier and make your changes there.
RCA will be making these available in every way they can, from adding them to their existing “low mass” bolt carrier to making them available as a standalone product. As for a price point, they’re looking at somewhere under $40 — less than the price of the gas block version.
