Superlative Arms Adjustable Piston System, Solid .750in Gas Block, Midlength, LH

The Superlative Arms Adjustable Piston System, Solid .750in Gas Block, Midlength, LH (brand part no. SABO-PS-LFD-M750SM) is a complete gas-piston conversion for an AR-15 upper, built left-hand (LH) for the midlength AR-15 gas system with a .750-inch gas-block journal.

Key Specifications

• It is a complete short-stroke piston conversion system that replaces the standard gas tube and key with an operating rod
• Piston operation keeps hot combustion gas out of the receiver, for a cleaner-running, cooler upper than direct impingement
• It is built for the midlength AR-15 gas system
• It is configured left-hand (LH), matching a left- or right-side operating rod layout
• It pairs with a solid (non-clamp) adjustable gas block
• It is machined for a .750-inch gas-block journal, matching the barrel’s actual journal diameter
• It uses Superlative Arms’s bleed-off adjustment mechanism, venting excess gas rather than restricting the port

Frequently Asked Questions

What does an adjustable piston system let me tune? The adjustable gas block lets you dial in gas flow for reliable cycling with a suppressor, subsonic loads, or to reduce recoil and wear.

Does this fit any AR-15 barrel diameter? It is machined for the diameter listed, so confirm your barrel’s actual gas-block journal diameter matches before ordering.
