I'm an ar newbie, so I'm going to say what I read on the reciept and the army guy told me. I have no way to verify it.
reciept says they use all milspec 'lowers'
the army guy says it is a M4.. same as he has back at base, with different optics and foregrip / bipod.
he knew exactly how to strip it. he had it broke apart, bolt carrier out and fire pin out in seconds.. very ipressive. I flipped thru the manual ( looks like a comic book ) and he pretty much hit every single step in the take down they listed.
fire pin does not look like tip broke.. and in fact.. manual has you using the firing pin as a tool to press other things.. etc..
on the ammo.. the ones that did not go pop, had light dimples. the ones that went pop had a good round indentation like any other centerfire I am used to. We tried ammo that was new from walmart a week ago, to some stuff I may have had 6m. again.. wolf, tan box steel case, tula, Black box, steel case.. remington, pmc, and federal, all brass.
different ages.
used a 30rnd plastic new magpul that came with ar.. plus a 5rdn stoeger? i use in a forgrip as a hideaway mag.. had a 20rnder unknown origin.. both new, steel. had some gi aluminum? 30's with the green follower. ( these cycle flawlessly in my keltec su16c/223 ). Armyguy put some 'clp' int he action, and the gun started stripping rounds fromthe mags .. oh.. 95% of the time. only had a very, very occasional failure to chamber a round. and when it failed to chamber, it wasn't a stop.. bolt went full to battery, fire pin dropped with a click on trigger pul.. when we opened the bolt.. we'd find the empty chamber.. pull charge handle.. see one go in, etc.. it was real hit or miss on if it would fire or not. didn't see any 'preference' for any mag or ammo make or age. it would misfire on all of them.. then hit on some..
he looked at the 'star' and the star chamber ? said fire pin protrusion looked ok.. etc..
so we were not seeing anything obvious.. and it does lok like it is going fully into battery.e tc.
i called co back... I have 2 options.
bring gun in and they can test fire it at their manufacturing facility ( a fewhour drive for me ).. or this weekend they will be at a gunshow that is an hour from me.. and I can bring it in.. but they can't test fire it there.. and they said they would 'look' at it. 'looking' don't make me feel confident I will be leaving with a gun that goes bang when I need it to. I have -0- confidence in that gun.. I'd grab a stick for self defense first....
i've been mulling over taking tomorrow off till lunch, and leave at dark thirty, and be at their store when they open in the am, and that would give me an hour for them to play with the gun, before I had to make a return trip and drive straight in to work. worst case.. if they needed to keep it over nioght and could bring it to the show on saturday, I COULD still make that show as I work at 11am on saturday, and could literally drive to the show at 9am when it opened.. walk in, get gun,a nd leave and get to work.
I just mapquested directions.. am thinking that is the best way for me to get a gun that shoots ??? looking at my work schedule.. I'll be working 6-7 days a week till the end of february... some half days.. some doubles. kicker is.. that even a half day of work almost makes it impossible for me to hit their city.. kinda sticks me..
that's why I'm thinking of just 'biting the bullet' so to speak and getting it over tomorrow..??
