The Superlative Arms AR-15 Adj Piston System W/Solid .750" Gas Block Midlength RH converts a standard direct-impingement AR-15 into a cleaner-running, adjustable piston rifle. Built around Superlative Arms’ patented bleed-off design, this mid-length kit uses a solid .750-inch gas block and right-hand operating rod to meter gas by venting excess pressure forward instead of forcing it back into the action.

This system is ideal for shooters tuning a suppressed or over-gassed mid-length build, or anyone who wants less fouling in the receiver and smoother cycling. With 30 locked adjustment positions at the front of the block, you can fine-tune operation for different loads while reducing felt recoil and blowback. The included ion-bonded one-piece carrier, piston block assembly, op rod, springs, and hex keys provide a complete conversion backed by Superlative Arms’ reputation for thoughtful engineering and durable construction.
