Hey guys, was wondering if any one is at a range and could snap a pic of the bcg while in battery (loaded chamber). I’m wondering cause i cant remember if the bcg is fully foward (like when chamber is empty) or is back 3/8" or so. I honestly can’t remember but would think fully forward when the chamber is loaded. I noticed this morning while coyote hunting about 10°F that the bcg appeared to not be fully engaged. Tried the forward assist but no luck. I won’t be able to get to the range till this weekend to check myself. Thanks
Huh?
What are you trying to ask?
When i loaded a round the carrier sat back about 3/8" from the reciever “window”. As if the bolt isn’t locking into the lugs.
Then your bolt was not in battery.

The bolt will be in the same location… loaded or not.
That’s what i thought. Thanks. I run Slip 2000. has about 100 rnds since last cleaned. prob needs to be cleaned again. Never had her out in that cold of an element.
Last weekend I was out in 14* weather.
The FrogLube I had on my BCG thickened up considerably.
It barely made it into battery and I had light primer strikes.
I had to warm the BCG in my car and wipe off the excess.
It had me rethinking running my BCG so wet.
I run Hoppe’s gun Elite oil with just a light coating. I was out in -5* this weekend and didn’t have an issue at all. But cleaning your gun will definitely make a difference.
My uncle lives in Fairbanks Alaska and he swears by Fireclean for cold weather firearm use. Fireclean seems to stay slick even in cold weather.
Yep. I’ve done Fireclean testing down to -25F. I do not apply excessively, though. I imagine Froglube would work fine down to those temps too if not applied excessively.
Paste vs. liquid might come into play as well, right? 
100 rounds, even 1,000 rounds, would be hard-pressed to make the bolt fail to go into battery.
Did you ride the charging handle forward when stripping the first round from the mag?
Actually, I doubt it. Paste application should be rubbed in and the excess wiped off. There generally isn’t enough goo to stop an AR unless you REALLY layer it on. Too much lube inside your firing pin channel or your trigger group are not needed, even in warm temps . The nice thing about paste is that it doesn’t migrate to those places.
The best thing about good lubes is that there is no reason to run the gun SOAKED in lube. Once treated with Fireclean or Froglube you don’t really need to run them as wet as some other lubes.
Make sure you manhandle your gun. Rip that charging handle back and let it go. I have had similar stuff happen when hunting though. Get out of truck, quietly load gun and then have to push on the cut out on the bolt or FA to get it to seat. Best bet is to load it at home where you can do it properly and loadly. Why people (hunters especially) are scared to have loaded guns in cars is beyond me. Being in a car doesn’t make them any more dangerous. Just dont be a retard and you’ll be all set.
No sir, i let her rip. I know better than to ride the CH. As far as the low round count and not going into battery im assuming i just didn’t lube the bolt good enough in key areas?
What is the brand of the BCG (or individual components, if you assembled it yourself)? Usually the bolt itself has some thicker lube on it and the interior of the BCG that holds the bolt is chrome-lined, so it takes a really, really dry bolt for it to be affected by a lack of lube.
Just for additional info, what brand/make of rifle is it? And what type of barrel does it have?
Bcm BCG and lower, Rainier arms 16" 1/8 ss barrel.
Just make sure to check your local gun laws concerning loaded rifles or magazines in a car as it is illegal in some states.
Do you have any usual wear or contact between the cam pin and the cam pin notch on the upper receiver?
Barring anything unusual, both should be in-spec. I’d break down the BCG, ensure that it’s clean, and lube it as necessary. I’d also lube the cam-pin and just put a light sheen of lube on the inside of the upper portion of the upper receiver (where the cam pin moves). Cycle the action a few times and see if the bolt goes into full battery. If it does, then try it again at the range this weekend and see if it exhibits the same problem.
Yea I’m defiantly gonna check that and the bolt lugs and magezine tonight. Thanks again
