Update on my issue - I ended up sending it to Kel-Tec. They did the following:Thanks for the reply.....mine is brand new...just took awhile for me to make some time to get to an outdoor range.......I have a Romeo5 optic on it, so I should probably take that off before sending it back to KT. I was going to clean it before sending it back, but, I was thinking that could make it more difficult for them to identify any issues with it that were due to manufacturing.....so I think I'll just leave it as is.....it shouldn't be too dirty considering I didn't fire many rounds through it.
(1) Replaced bolt head assembly
(2) Updated firing pin with newest revision
(3) Polished feed ramps
(4) Tested, no malfunctions, with 55gr .223 Federal American Eagle, gas set at +8
I normally use 5.56 Federal, and I hope to go to the range tomorrow.
Any suggestions on gas setting for 5.56?
