Another buffer/retainer problem

[duc748bip]

Here is a picture of a busted buffer retainer pin. POF upper and lower the silver crescent shape in the buffer tube is wear from the Bolt carrier tilt.. (I think)
But i don't know why the retainer pin will snap or if it is normal wear.

From what I've seen on other forums, over-gassing or a soft buffer could do it. I've even heard of hot-loaded rounds snapping it right off.

That's quite a bit of carrier tilt.

Get one of these or this. Better yet, talk to POF about getting a new buffer tube and/or carrier that fixes the problem of carrier tilt. The older POF carriers have the problem.

Regarding the "heavybuffer" with the extended buffer that lock with the BCG. How do you break the rifle open? Or you had to pull both pin and try to separate upper and lower?

I'm gonna go out on a limb and say that's a piston rifle...

Pull both pins for disassembly. Assembly would require you to pin the pivot pin and use your finger to push in the buffer slightly so the upper can close.

Not to be ....

But I have been shooting AR15's since 1968 and I have never seen all the difficulties with parts/assemblies that I have seen on this forum.

All the AR15's/M4's and, Yes M16's, never have I seen such problems.

All mine work from the first shot. Am I lucky???? I don't think so.

I have had Colt, DPMS (which I don't like), Olympic Arms (who makes great barrels), Del-Ton and what ever. Never had any problems.

I have one AR15, that has over (I mean well over) 10,000 rounds, never a failure. And it's on the old DPMS "CAST" receiver.

Obviously, someone is doing something wrong...These rifles are easy, plug and play! Heck, you just put the parts together and you have a rifle. Nothing like the AK-47 which you actually have to make.

What is causing this???? To be honest, I don't know. Maybe lack of skills/troubleshooting, I don't know.

A bunch of rookies ind this forum and say "OOOH! I can build my very own AR-15!" (this isn't aimed at anybody in particular). But these are people who have no business working on firearms.

And people insist on using all kinds of gimmicky crap like piston rifles (which is why the OP is having the problem with his rifle, it seems.)

Eugene Stoner was a genius. When you stick with his original design, you do not have any problems.

rifle

Is the rifle a factory build or built up rifle?Is it a piston ?.What caliber.?looks like you have to much gas and wrong buffer spring and buffer.I have several piston rifles and never have any problems with them,the oldest one has about 6 thousand rounds threw here.

If it's gimmicky, why is the U.S. military moving towards piston rifles for all the soldiers?

POF only makes piston rifles.

They're not.

[vikingm03]

Looks like you have a lot of carrier tilt, which eventually wore away enough of the buffer tube for the bolt carrier to come into contact with the buffer retainer? At least that's my guess

[xpbprox]

The AR is a position rifle, just that with the DI it uses the BCG

It's a solution for a problem that doesn't exist.
Some upper echelon jackwagon is cementing his career by instilling it, whether it makes sense, or not.
