A well tuned weapon will perform better and offer a more pleasant shooting experience. The Superlative Arms adjustable gas block can function as both a traditional restrictive style or a patented "Bleed Off" type. By reducing the pressure entering a direct impingement gas system, the weapon can be run cleaner and smoother with less wear on parts and reduced gas block back to the shooter. Eliminating excess gas can also help keep the weapon cooler and reduce felt recoil by delaying bolt unlock and slowing the BCG. The Bleed Off method of gas adjustment also requires less maintenance than typical restrictive tuning. A tuned gas system is a must for SBRs, suppressed weapons, and competition firearms with specialized parts such as lightweight bolt carrier groups.
Superlative Arms has proven itself to be a leader in variable gas blocks, while still being very affordable.
This is a clamp on variant. Clamp on gas blocks do not require dimpling of the barrel. This model is a weekend DIY change-out, and fits on even the tightest of 0.75" gas journal barrels.
