PTI Parts AR15 H3 Carbine Buffer (5.5oz)

H3 Carbine Buffer (5.5oz) – Tuned for Controlled Chaos
Dial in your AR’s recoil and tame the beast. This H3 buffer is built for carbines running collapsible stocks—especially those dealing with the blowback of suppressed setups, short barrels, or over-gassed pistols.

Whether you’re tightening up a new build or solving cycling issues, this buffer delivers. Outfitted with a proven weight combo—1 steel, 2 tungsten—for a total of 4.7 oz of finely-balanced mass. Drop it in, and let your rig run smoother, harder, and cleaner.

Pair it with a RED spring (extra heavy) for peak synergy and ultimate recoil management.

Built not to flex—built to function.
