Failed buffer

[popper]

Buffer (no name) has ~ 300 rnds through it, AR pistol with supers. Well range day didn't go good today. Replace batterys in sight, shot some more and - bolt won't go back very far. Buffer has screwed in plastic buffer stop that came unscrewed. Screwed it back in a did a few more shots. Sure the threads are stripped on the plastic - don't see any other damage. IIRC, 3 weights & 1 shim but it still rattles after re-assembly. It's a cheap build used for pig gun so no fancy stuff. Aren't most buffers pinned?

It's supposed to rattle.

Should have 3 weighs and 2 shims that move (rattle) when you shake it.

[popper]

Ahh, only one shim. Carbine weight. Nylon buffer just has threads stripped any second source for it?

[Boolit_Head]

Probably easier to buy a new buffer, and a better built one while you are at it.

If youre running a pistol with only supers, you may want to replace it with an H2 weight buffer. If youre going to be buying a nee buffer anyways

As said, they do rattle, and should be pinned.

[Dolomite_Supafly]

The plastic part should be pinned. If not replace it.

It probably doesn’t have threads and is just pressed in, like most cheap buffers.

KAK makes a nice configurable buffer. Got one and like it.

Threads stripped, pinned replacement.
