Up until now I have only fed the rifle .223 and never had an issue.
I was at the range today firing 5.56 \ 55 gr and noticed it failed to lock into open breach the 1st time. (No FtF or FtE)
Didn't think much of it so I sent another 30 down, same result so I stopped and went to the pistol range.
The barrel is a 16" (not sure what brand) with 5.56 NATO 1/8 stamped on the business end.
Lower is an ATI Milsport Multi-Cal.
Interested to see if there's something I should tweak or replace. Buffer tube spring perhaps?
1,000+ rounds of .223 no issue.
