JR Carbine bolt sticks open issue

What the fvck gave you this idea? The manual says to put a little Slip 2000 on the bolt and let it dry before assembling. So, perhaps this is why mine has run flawlessly and you're having problems.
Edit: Quote from page 19, Assembling the bolt:
Before inserting the bolt into the receiver, spray a coating of Slip 2000 gun lubricant on the exterior of the bolt and allow it to dry completely.

After re-reading the manual online, they recommend EWL and not using gun oil. Weird.
Still haven't had time to dismantle and fix it up.. most likely the oil on the bolt was causing it to be stuck in back position.
I agree with an earlier statement though, I'd never buy the JR Carbine if I knew then what I know now about it.. it's seriously going to fail after 2000+ rounds.
I have put lil under 3000 rounds through my jr-45acp and I'm not getting any problems of the bolt sticking in the back position while firing, but sometimes if I pull the bolt all the way back and hold it there for a second or two it will stick, until I nudge it so it flies back forward.
My main issues with the Jr45 is the constant stove piping issues, I even bought the glock mag springs that just right makes for the glock mags, to make it work better. They are not helping and with the new springs you can only fit 9 rounds in a mag, and it didn't solve the problem. Also don't buy the cheap norinco 45acp ammo it doesn't work well every time.
my bolt begins to stick after about 1000 rds, cleaned it when I first got it and decided to see how long I could run it before I got a stoppage, required about 3 trips to the range and at around the 1000 rd mark the bolt began to delay closing and eventually stayed open. cleaned, oiled and wiped dry, ready to shoot again. stopped counting after 5000rds, had 2-3 stove pipes in total ,all on last shot during rapid fire, have not had any real problems, love the jr. p.s. mine is in 9mm.

My JRC in 40SW will stick if I pull the handle all the way back with a bit of force. I've never had it stick open like that when firing, as I'm pretty sure the bolt does not go back that far when actually firing. I keep it lightly lubed with G96 and it runs pretty well. I had a problem earlier with a few ftes in the winter and I found I was oiling too much and the oil was getting a little thick in the -10C or below temps. I also had an issue with light primer strikes and a phone call got me talking to Tom and after a brief discussion he sent me a new firing pin and spring.
I try to not pul th bolt back much beyond the hold open slot and it all works beautifully. Prolly run around 3000 rounds thru it and most of those have been since I got the firing pin sorted with zero problems since then. I also gave up cleaning it every time I went shooting, as it's a bit of a pain, and it seems to run perfectly without stripping each time out (maybe 200-300 rounds each visit). About all I do is run a snake down the bore and spray a little g96 on the bolt and wipe off any excess. Definitely not running dry, but not super wet either.
