    ar15 carbine, not unlocking

    Ok. So if one of you ar armorers couldhave seen the malfunction you could have told me what it was....but it WAS the gas system, not the gas key, but the gas port on the barrel itself. To small, it was restricting the return... now it was under an A2 sight, so that made me think there would not...

    ar15 carbine, not unlocking

    the cam pin may be the only thing i have not tried out. I'll switch those out before I spend money on a new carrier. as for the gas key I have cleaned it out multiple time with pipe cleaners, along with the gas tube. I know the problem lies in the bcg, but what? gas key is good. gas rings on...

    ar15 carbine, not unlocking

    it is a full auto type carrier. although i did not specify I have been over this thing and the recomendations, you also may have missed where I have tried exchanging all the components including different lowers just to be sure. I even swaped charging handles. the gas key is peened into place...

    ar15 carbine, not unlocking

    finally. finally got to the range today. took a known good AR carbine, and started a parts swap, mine was still not functioning, and we have narrowed it down to the bolt carrier itself....now..no idea why. the 2 bolt carriers we have ar not the same, mine is what I am calling a military type...

    ar15 carbine, not unlocking

    I'm using auto body 600 grit paper, and so far Ive buffed... bolt lugs, extention lugs, the bolt body, bolt face, the inside of the carrier, and finally the channel the cam pin rides in, and the last seem to be the thing that eased the most tension while manually operating the bolt. just need to...

    ar15 carbine, not unlocking

    lubing with CLP, normal stuff like I used in the Marines, we are not afraid to lube it...oh yeah..semper lubitupis... factory and reloads, brass and steel cased. OAL is good as well as charge in the reloads. factory was new 3 different brands. etc. I may have a fix, but I need to go shoot...

    ar15 carbine, not unlocking

    As far as the bolt being mil or not, It is new, and looks like a mil spec but not a military part. I filed a few more things here and there and the carrier now moves freely in and out of battery with ammo, sticking is very reduced...now to re-shoot, and hopefully just break it in with use...

    ar15 carbine, not unlocking

    PSA only honors original purchaser, I am not. let see..as far as the gas block it is an A2 front sight set up, I have used multiple brands of ammo. It will extract when when the bolt unlocks, the extractor is good, the ejector is awsome. I just returned from the range, and got it to fire 3...

    ar15 carbine, not unlocking

    sorry keep remembering things as I read.. there are scratches on the case sides but these seem to coincide with the locking lugs in the chamber upon extraction, you know the one side of the case is being pressed outward by the ejector pin.

    ar15 carbine, not unlocking

    also, I can drop a live or fired round into the chamber, make sure it is seated and run a cleaning rod down the barrel and easily push the round out, no sticking..obviously it is dissassembled in case abyone was wondering...

    ar15 carbine, not unlocking

    I'm not positive about the buffer spring type, and the chamber "looks" clean and polished..but.. I am going to attempt to use a different bolt carrier group from a known to function fine AR and see if it still does the same, alternately I am going to try mine in the other AR to eliminate or...

    ar15 carbine, not unlocking

    Ok so I have a Palmetto State armory upper, carbine, 16" barrel, ATI poly lower. this info I think is inconsequential, but there it is. It is factory built, never or rarely fired...probably not more than a few rounds, why? becase it is a single shot AR at this point. Now I have considered...

    so I from what I have found, I need the standard 3 die set plus a decaper without the pin for a final "resize", due to the fact that apparently the bullets swell the casings so they do not easily fit the chamber. I also found a fellow on another post of mine showed some nice pics of JSP with a...

    cz 52 modernized

    those are some nice wood grips..as for carry, mine is on my side now, a little lighter than a 1911, IWB carry. I like that expansion of JSP, because I am gathering info on reloading this round also. and since I commented on the penetration topic, I keep coming on information on these steel...

    cz 52 modernized

    I've been wanting to try out the yugo 57, or one of the "browning" looking variants, I have not seen many around where I am, and the one I found was stolen right out of the display case at the pawn shop it was in. I like that chrome, looks nice, I've been considering a coating of some kind on...

    cz 52 modernized

    I use modernized loosely, as what I have done is replaced old parts with new and upgraded designs. With these additions I feel as confident with the cz 52 as a carry option as I would with say..a 1911. how is this you might ask? well let me tell you what i have done. First thing was to replace...
