Bcl102 failure to feed and apparent undergassing issue.

For my own knowledge can you list a few things that you have seen wrong with the bcl bcg? Have you had any experience with po2 or po3 bcg? What would be a decent upgrade ?? Is it worth keeping the carrier and replacing the bolt?

well... my gen2 rifle has exactly these issues. I just put the factory trigger back in, I will let you know when I shoot it this friday.
I am expecting that the trigger was not the issue
 
The other issue I have is that when the bolt is locked back if you tap the stock it slams the bolt shut. Doesn’t make me too confident about sticking my fingers in there
 
Send it in, sucks that a 2k rifle doesn't work.

Kinda glad I skipped the hype about the "almost 2k AR" and just bought a Browning BAR .308, brand new for 1350$
Im 100% happy with my rifle. Its unfourtunate that some people are having small issues. What im not understanding why your here? You dont own a BCL and you're not adding anything constructive. Happy shooting with whatever toy you pick.
 
That is the wrong test, that is a method not necessarily for an AR-15. The test for an AR-308 is different.

Will test it again as per Mallice's recommendation:

No. This is completely wrong. :)

The actual test is to remove the firing pin retainer, firing pin, and cam pin, and then hold the bolt carrier with the bolt facing downwards. If the bolt falls out under its own weight, then the rings should be replaced, and that's only assuming your are not using mcfarland 1 piece gas rings (they have less friction than 3-piece rings).

ETA new vid....yanked the firing pin retaining pin, the firing pin and the cam pin as per Mallice's post.


The bolt didn't exactly fall out of the carrier without some shaking.

I have a feeling it might not have been cycling properly because the thing was bone dry? Anyway, lubed it up with some CLP and will try again this weekend.

I meant for a peak and poke. Lol �� the point was made to illustrate the hazard
Being new to the ar platform I wasn’t sure if this was normal or not?

So I took my Black, 2nd pre order, SN about 480ish, out to Range on Monday night for first time ever. I put 40 rounds thru it, seemed to work fine, with nice tight groups (indoor range, so no teaser pic) Loaded mag prefers to be inserted on an open bolt and one FTF, but otherwise shoots pretty good and consistent. I can see a more beefier stock in the near future, but nothing else was troubling.

I used Hornady Steel 155gr BTHP I had kicking around, next time I'll use Norc surplus.

Finally took out the bcl to test it out. Shooting hinterberger (spelling?) Ammo. Feeding out of a pmag and an ASC 10 rounder magazine. Couldn't go through one mag without at least one failure to feed where the round ends up as you see it. Pull back on the bolt a bit and let
go and it chambers and shoots fine.

Also, rounds are basically dropping at my feet, maybe a foot or two to the 3 oclock. But half the time I can bend over and pick up the brass without moving my feet. I mean it's an awesomely soft shooting gun but that seems to be too soft.

Thought?

I am testing a carbi e spring and buffer tomorrow, I will let you know
 
Take the BCG out and stand it on end and if it will not stay up on its own weight tbe gas rings are toast. My rifle has functioned perfectly on all types of ammo. Not 1 FTF or FTE but i bought some good gas rings from wolverine ($15) and changed them out. The rings are compmete junk that come from factory when held against a set from DD. Its to bad all tbese small issues are giving this awesome rifle a bad rep. And it loves to be ran wet!!!
I don't know where the internet got this one from, but this is absolutely not the proper way to test gas rings.

The proper way to test gas rings is to take out the cam pin and firing pin and to hold the BCG in the air with the bolt facing down. If the bolt stays there, the rings are good, if the bolt falls out, the rings need to be changed.

Wayyyyy too many good gas rings get changed out because of the improper method.

An AR will run on one lone good gas ring.
 
Some of their AR's had this issue too, not very positive contact with the bolt catch, removing a mag would be enough for the bolt to drop... suckage....
The other issue I have is that when the bolt is locked back if you tap the stock it slams the bolt shut. Doesn’t make me too confident about sticking my fingers in there
