Great forum - i've learned a lot lurking over the fast few weeks. Based on info from several different sources I decided to purchase a Colt 6920 and picked one up over the weekend. While checking it out in the gun store i didn't notice any problems but after I got it home and took it apart for cleaning I found some fit issues:
1) the rear lower receiver pin hole is apparently egg shaped, top to bottom. When I press down on the upper I can see the rear pin moving up and down.
2) the rear upper receiver pin hole is visibly egg shaped, front to rear.
3) the upper and lower do not fit together well. when the rifle is held sideways to the light I can see a thin line of light in between the upper and lower. This is especially apparent near the rear of the receiver above the rear takedown pin where the receivers begin curving upwards toward the charging handle. a piece of paper will easily fit between the upper and lower receivers where the bolt carrier meets the buffer.
The upshot of this is there is noticeable slop between the rifle receivers, both up and down and from side to side. it is especially apparent when using a forward grip attached to a DD Omega rail, and this is my excuse for not picking up on it in the store.
Based on searches on this forum, the wiggle issue seems to be normal on weapons that have been well loved (read: used). being able to see daylight between the receivers doesn't necessarily bother me - after all, my Glock works just fine and I can stick my hand between the slide and receiver. But, I do find these issues pretty annoying after spending $1299 on a new rifle (and it is new. it came in a sealed box with all accessories from a reputable dealer in Dallas). Maybe I just want to complain, but I suppose i have a few questions:
1. how normal is this on a new rifle, especially a Colt?
2. can I expect any function or reliability issues? I wouldn't really think so, but if I can easily slip a piece of paper between the upper and lower I assume grit and crud can get in there.
3. should i throw a screaming hissy fit and demand that someone (maybe the AR15 fairy?) take it back or fix it? On one hand I do intend this gun to see some relatively heavy use, but on the other I would like to be the one to wear it out.
Before telling me to suck it up, please know that I'm snake-bit when it comes to firearms and am getting increasingly fed up. i've sent at least three back to the factory for repairs, one of those needs to go back, and damned if there's yet another one on my counter with a UPS label on it, ready to get shipped off. So i might just throw a hissy fit anyway. I appreciate any responses.
