Griffin Armament Suppressor Optimized AR-15 H2 Buffer - A5

The Griffin Armament AR-SOB-A2 delivers rifle-length buffer function in a carbine-size system, letting suppressed AR-15 shooters run an A2 rifle-length spring's smoother, more reliable operation without switching to a full rifle-length buffer tube. Built from 10 individual components with a staggered impact, urethane-buffered design, this AR-15 buffer combats the over-gassing and undersized buffers that plague most factory carbines, especially when running a suppressor.

Features:

• 5.6 oz weight
• Requires an A5-length buffer tube: Armalite AR10 carbine-length tube, Griffin AR-10 Maritime Receiver Extension, or Vltor A5 tube
• Requires an A2 rifle-length action spring (not compatible with a standard AR-15 carbine spring)
• Brass shock-dampening weights, heat-treated 17-4 stainless steel construction
• Staggered impact hybrid buffer design
• Telescoping buffer head with CNC-machined weight platter
• Chambered for 5.56mm or .300 Blackout AR-15 rifles

The A2 rifle-length action spring's greater number of coils promotes smoother operation and better reliability than a standard carbine spring, a design preference that traces back to engineers who worked directly with Eugene Stoner. The AR-SOB-A2's staggered, sequential impact of its internal weights increases system dwell time and reduces bolt speed, improving chambering reliability, especially in suppressed configurations where increased gas pressure would otherwise push an underweight carbine buffer to cycle too fast.

Griffin Armament designs suppressors and recoil-management components focused on solving the reliability problems suppressed AR-15s create, applying that same engineering to the AR-SOB line of buffers.
