Buffer length

[dennisp5]

I am slowly building a 9mm ar that I just put in a YHM 9mm buffer. The bolt still travels 1/2" past the bolt stop. Is this too far? I don't want to break the bolt stop. 

Thanks

If you don't mind pre-loading the recoil spring, you can stack enough quarters inside the buffer tube to shorten the stroke.  

 

I put in just enough quarters that the bolt will clear the bolt catch by a 1/4" or so.  This allows me to lock back the bolt during unload and show clear. My main match PCC has over 7000 rds through it without a single broken bolt catch.

 

If locking back the bolt is a feature that is not needed, you can add a few more quarters and shorted the stroke even more.

I have 6 quarters in mine with the Blitzkrieg hydraulic buffer and smalley spring. Super short stroked lol, bolt catch does not work at all. I have a chamber flag so who cares right?
