Lonewolf McQuade Posted July 4, 2021 Author Report Posted July 4, 2021 Out of curiosity, why oil over the use of grease? To thick, collects too much crap, temp issues?
Lonewolf McQuade Posted July 4, 2021 Author Report Posted July 4, 2021 (edited) Alrighty then, got the little sucker swimming..... knew I'd find a use for that old rotisserie chicken container Edited July 4, 2021 by Lonewolf McQuade
Belt Fed Posted July 4, 2021 Report Posted July 4, 2021 Grease hardens over time, also in cold temps it hardens. Oil is better. don't throw that oil away.lol what i like about mobil 1 is don't get rank over time. some oil will and i have used some gun oils that smelled like crap. far as storing it. don't apply a ton of it to put it up. but when you go to the range crack it open and pull the BCG and apply it generously.

Good tips, thanks Rick👍. Gonna let the BCG soak overnight. Heading out hog hunting again tomorrow (boss actually called me today & said to take tomorrow off, fukr must be sick or something 😂) so I'll probably just put BCGin a Ziploc bag & install when I get out in the field. Ill report back tomorrow night when I get home if LUBE deficiency was the only issue with the gun.
Armed Eye Doc Posted July 5, 2021 Report Posted July 5, 2021 Be sure to wipe off the bolt face before shooting. You don't want the oil getting in the chamber.

Lonewolf McQuade Posted July 5, 2021 Author Report Posted July 5, 2021 I been running the rifle with less lubrication than I should have, but not sure that's the issue I'm occasionally having with stuck fired cases. BCG is cycling, resetting trigger, just not extracting case. We'll see tomorrow
Armed Eye Doc Posted July 5, 2021 Report Posted July 5, 2021 Can you get a close-up picture of the bolt face. A squared off extractor can cause problems.

A squared off extractor can cause problems. I posted some on page 19 of this thread. I can take more if you need a better shot. If you look at the brass, the one that got stuck in the chamber isn't shiny like the rest that worked properly. It has black marks as if possibly a little hotter of a load?

shooterrex Posted July 5, 2021 Report Posted July 5, 2021 This is the ejector I went with. https://www.kakindustry.com/kak-bcg-ejector-308 The also sell extractors and you need a new one.

Thanks. These parts are the same for all AR 308 , including Armalite?

That's a bad piece of PPU brass. Is that the only one that stuck and then had the rim ripped off? Do me a favor, if you will - remove that extractor and get a few close-up pics of that thing, so I can see the groove that grabs the rim, then an additional pic of that extractor hooked up to a piece of brass, with the hook sitting on the rim. That extractor is definitely effed. That ejector has a very tiny raduis to the edge, but it's pretty square-faced. You could definitely remove it, chuck it in a hand drill, and round that edge off pretty well.

Yesterday, I had fired about 30 rounds (not rapidly, 1 here-1 there) before I got a stuck shell. Cleared that case, also got a broken off rim. Fired 6 or 7 more and yotv1 more stuck also broke off piece of the rim. This ammo is all from the same case I ordered a year or 2 ago,. Ive shot 300-400 rounds out of that same case of PPU without issue out of the Tavor 7, RPR 308 bolt action & the AR10. Never an issue till tast Saturday. 42 minutes ago, 98Z5V said: Do me a favor, if you will - remove that extractor and get a few close-up pics of that thing, so I can see the groove that grabs the rim, then an additional pic of that extractor hooked up to a piece of brass, with the hook sitting on the rim I've not taken one apart yet. Just drive the pin straight through? Edited July 5, 2021 by Lonewolf McQuade

Push down on the tail of that extractor, and compress the spring, makes getting the pin out a little easier. Use the tip of the firing pin to get it started moving, then you can grab it on the other side and pull it right out. Was this gun ever fired before you bought it? How many rounds through it so far?

Correct. I can swap some parts, if you want, and test fit. They both look the same to me, I've never noticed differences in those two parts, between Armalite and DPMS-based. Keep track of the firing pin spring when you take that BCG apart. Edited July 5, 2021 by 98Z5V
shooterrex Posted July 5, 2021 Report Posted July 5, 2021 The extractor yes just push the pin through. The ejector take 2 45acp cases. Put 1 on the tail of the bolt. Put 1 on the face of the bolt w/the head of the case against the ejector and clamp the whole thing in a vise. The cases keep everything from getting screwed up. You will need to drive the pin holding the ejector out w/a punch. An extra set of hands would help.

Very low rounds through when I bought it, I saw almost no wear signs anywhere other than some brass dust on the bolt face. Damn near looked brand new inside. I've put at least 150 -200 rounds through it. 17 minutes ago, 98Z5V said: Keep track of the firing pin spring when you take that BCG apart. Ive had the bcg apart & clean it every time i shot it, i just have not disassembled the extractor or ejector & wasn't sure if it was any different than an ar15 or not.

I should be able to follow your instructions easy enough.

Thanks For me, getting the pin out for the extractor was easy, it’s the ejector that I spent an hour or two with. Had to make a jig to hold a case in line with the bolt to get that spring under pressure for proper pin slippage, driving that pin out with a tiny 1/16” punch. I even ground that punch skinner for that ejector pin. Extractor is a breeze, however. i see now shooterrex es 45acp comment. That sounds better than how I did it with one 308case.
