Interesting. I've never encountered a buffer tube with the recess.Bitter Clinger wrote:
But it did not "break thru" the buffer tube. There is an "on -purpose" recess there in order to catch the outer lip of the spring pin. Here is my S&W AR-10:

Re: Buffer Retainer Broke Through Buffer Tube
A few months back I had a malfunctioning problem with a 40 year old SP1 Colt AR.
The buffer tube had loosened and backed out slightly allowing the buffer detent to raise up too high and it was bent by the buffer slamming into it. There isn't a castle nut on a full stock old style AR.
A few weeks later I read about how up until the middle 60's, M16s & AR 15s were drilled for a roll pin that ran perpendicular to the buffer tube.

How did that happen? The eggplate is what indexes your extension. The eggplate would have had to rotate and you'd think you would notice that...bulletslap wrote:A few months back I had a malfunctioning problem with a 40 year old SP1 Colt AR.

Re: Buffer Retainer Broke Through Buffer Tube
I bought a Bushmaster AR-10 (technically, an Optics-Ready-Carbine in .308) a few years ago. Whenever I fired it, after a few rounds the buffer retaining pin and spring would pop out. The spring got bent, so I called Bushmaster and they sent a new pin and spring. The cure was just as TAM said, loosen the castle nut and screw the buffer tube in one more turn. It's been working flawlessly since then.
