- Sorry! Double post!

Well, at least you know that the issue is now not the top plastic part of the magazine that touches the nozzle, but the body itself. I'd do what danielsilva suggested and try to mark (with chalk, graphite, etc) the body of the magazine (approximately the top 1/3 or so) and then insert it into the lower receiver. This it'll let you know where exactly it's rubbing/catching. It could be that the magazine has just expanded for some reason. It wouldn't take much to make the magazine not fit, either. Just a couple of millimeters worth of expansion.
-
If you separate the upper/lower receivers, does that magazine fit normally into the lower receiver okay? No issues inserting/releasing it?
-
Well, I'll take your word for it in a real gun, but it honestly did stop the wobble in my WE. For how long, I have no idea. But, we'll see. It was only $5 US, so no big deal. And Daniel, you're talking about the RA-Tech pin, right?

Jkpics, Danielsilva, thanks for the suggestions. I'll definitely keep those in mind if I have a similar malfunction again. Fortunately it was just a failed nozzle return spring that wouldn't let the bolt fully seat inside the bolt carrier. I picked up two spare nozzles and the gun is up and running. By the way, if anyone has upper and lower receiver play, a modified AccuWedge will solve the problem. The AccuWedge is made for real guns, but the AR15 version fits with a slight modification. Out of the box it sits too high inside the lower receiver (you won't be able to close the receivers),

Well, I took apart my bolt carrier group today and found out why it wouldn't seat completely in the chamber, lacked power and just generally didn't work right. You know that spring in the nozzle? The one that links it to the bolt carrier? Well, it snapped and coiled up behind the nozzle, not allowing it to completely seat inside the bolt carrier, which subsequently didn't allow the entire bolt carrier assembly to seat correctly, which then meant I couldn't split the upper/lower receivers, etc. I'd take apart the nozzle assembly as well, but I don't have a punch small enough to k

I got that *fruitcage* out! Thanks NonEx and Infantry. I popped the pins back in, removed the outer barrel and then the inner barrel, and then whacked the bolt carrier with a hammer and punch. That moved it forward a bit into the chamber, and then I could separate the receivers and pull the bolt carrier back out. NonEx, Infantry, if I could kiss you guys, I would. Not that you guy's would like that, but, you know. Thanks for the help. I really do appreciate it. There wasn't anything in the upper or lower receiver that shouldn't have been there, so I think my nozzle just up and died

Well, the bolt carrier cannot exit through the rear if the upper receiver isn't separated from the lower receiver because there's that goofy looking bit on top of the bolt carrier. That bit (on a real M16/M4/AR15) is what, for lack of a better term, is "hit" by the gas from the gas tube to move the bolt carrier to the rear, in addition to running in that channel of the charging handle. In any case, that bit hits the loop of the lower receiver. Likewise, I don't think it'll exit through the front for that reason either. And the forward assist never did anything on my M4 anyway. BUT, I coul

Well, I ran into a bit of a snag yesterday while target shooting. I noticed that the gun suddenly lacked power and sounded different, so I immediately stopped firing and saw this: It appears that the nozzle within the bolt carrier seats into the hopup okay, but for some reason, it's not seating fully inside the bolt carrier. When I dropped the mag and locked the bolt to the rear, I saw this: I pushed the nozzle back as far as it would go into the bolt carrier by hand, and it stops here: It DOES NOT go back any further. So, since the bolt can't go all the way forw

Ha, I thought that too. The '9/11 configuration' just sounds, well, yeah. Anyway, how do you like Magpul's RSA? Does it snag on any of your gear? Is it fairly sturdy? I've been looking at one of those so I can ditch the factory front sling mount - it's developing a bit of play since I crank down on it with a VTAC sling.
-
I actually like your "B" setup, it looks less cookie cutter than other M4s. But I also like the 7/11 and 9/11 configurations. Do you need a lot of rail space? Do you like to have a more forward grip on the gun? If you do, run the 9". If not, run the 7", as it's cheaper and lighter. Not by much, but every bit adds up.
-
Thanks for the help regarding the magazines everyone. Has anyone had the problem with the OB hopup turning itself "off"? I've put about a thousand rounds through the gun, and the grub screw for the hopup is loosening itself now. I'll reset the hopup, fire 90 to 120 rounds, and then BB's roll out of the barrel because the hopup is "off" and the grub screw is almost completely backed out. I'm thinking it's because of the recoil but I'm not sure. I'm going to put a *very* small amount of blue Loctite on the screw and see if it helps at all.

Good idea about leaving the spring partly cover on! I did that and it worked perfectly. Thanks!

I installed and tested my open bolt kit today, and I have to echo NonEx's statement about the gun being consistent and zero'd in. I haven't had a chance to test at a distance, but close range accuracy is great with my biggest (worst) grouping being .75" at 5m. It doesn't seem to be a gas hog either, as I could consistently get 2 magazines worth of firing per fill on green gas. However, I did have a problem. After installing the new bolt/hopup/barrel/trigger pack/bolt catch-release and lubing the entire system, the bolt would only move back about half of it's original travel when the charg
