Running an AR15 with no buffer retaining pin?

[Gunsnwater]

Somebody also makes a shim for the back of the bolt carrier. Basically the relationship between bolt carrier at full lock up to the buffer and the retainer pin should not allow impact of the pin by the buffer.

I think lapping the shoulder on the upper to square up contact of the barrel extension should bring the carrier back a little and could help in this regard and possibly a different carrier could be slightly longer.

18$? Ouch. How many replacement milspec retainers can you get at that price?

Add in buffers as they can get beat to snot and need replaced.

Will it actually cause the buffer to fail or just look unsightly?

It's a shearing scenario. The $18 sounds high, but if it shears during a SHTF and gets into the FCG (which it is known to do), the $18 gains a better perspective.

I run all of my ARs without the buffer retainer assembly. On most of my ARs I use the ArmaSpec silent recoil spring which is a self contained buffer and spring assembly that looks like a big glock recoil spring and sits in the receiver extension. The retainer is not required and it is a failure point. Choose your path...

It's not necessary. In fact, I've seen guns lock up if they sheer off. I run my PCC without one because I like pressure on the carrier all the time on a blowback gun...I also run a a rifle AR10 spring on it.

How much of a pain is it to get it all closed?

It's a non-issue.
Hold the buffer in while you close the upper and lower together. Done.

Here you go...

Hmmm. No kidding. I'll may have to give this a try.
