Random thought, tear the rifle down and get out a flashlight and look at the feed ramp and see if it is flush or just below the chamber... if the ramp is jacked up it will ruin the whole thing.....

The feed ramps look pretty good to me. They are M4 feed ramps, and while they don't go very far into the upper reciever, they do. I'll see if I can grab a pic.

Those ramps do not look to good. They look short and sharp.

What ammo are you using?

They are sharp. When just pushing a round over them by hand, it will sometimes 'grab' the bullet. New Winchester white-box 55 grain FMJ from Wal-Mart and some Federal.

These are locking lug issues. The lugs on the end of the bolt are not rotating/seating behind the lugs in the barrel extension.
Other than dirt, SOME of the causes could be;

Improper barrel alignment (check barrel indexing pin)
Improper bolt rotation during chamber **
Improperly manufactured barrel extension

** Hold bolt assembly with bolt retracted and facing away from you. "Flick" the assembly in a downward motion, and the bolt/cam pin should easily extend.

EDIT: The receiver ramps look good, but the left barrel extension ramp appears to have excess material protruding along the right side of the channel, near the center ramp guide.

Sorry, I don't understand...are you saying I would be holding the bcg horizontal and flick the gas key? or, hold the bcg vertical, bolt facing the ground, then flick the back of the bcg (the flick breaking the tension of the rings and gravity pulling the bolt into an extended postion)?

Also,

There is...the copper colored stuff you see on it is, well, copper. Simply running a round through there (manually feeding a round, but mimicking the the natural path of said round) sometimes causes the bullet to 'snag' on that edge of the ramp. My guess is that this resistance is causing enough resistance to slow the bolt down enough to prevent it from fully chambering the round.

C-grunt · 09-04-2012, 03:49 PM

He is saying to swing the bcg in a downward motion to see I the bolt extends out. It also should stay in the extended position if you stand it up on the bolt.

I'm thinking that you might have a problem with your feed ramps if you can feel a ledge and rounds are hanging up on it.

Migh want to send it back to the company and let them handle the problem. What brand is it? I don't know a RMA.

bcg is good...enough tension to hold it up, not so much that it can't be 'swung down.' It is a Daniel Defense. I'm still waiting on the promised RMA (Return Merchandise Authorization) so they can look at it. My guess is that they'll just throw a new upper on it and send it back to me--which I would be fine with. I just want a reliable rifle.

My brother in law has one for his AK74. Works pretty well. I wouldnt buy one as I think its a waste of money and ammo but it does work.

TwinscrollGT35R · 09-06-2012, 02:56 PM

Oh yes its a huge waste of money.. but the fpsRussia guy made it look like a **** ton of fun. So I might pick one up with a 100 round drum. Its not a permanent piece. So even if its a weekend toy then sell it.. should still be a kick in the pants. After shooting bmg so much now.. i gotta get a new skirt for the ar to spice up our relationship.. otherwise I'm going to dump her.. she doesn't have the kick in the pants fun factor anymore. And I already have been sleeping with her sister the hk mp5

Sent it back to them today to have them look at. Thus far, they've not been impressive, but we'll see what they say.

Mine has never had an issue. Even with it sitting in the dirt with the 50 cal muzzle blasts of sand and dirt all over it. I can pick it up and its 100%

TwinscrollGT35R · 09-07-2012, 12:54 AM

I'll get it all clean and post up another pic in a bit. So I don't get burned at the stake for having a dirty tool.

I dont think Ive cleaned my Colt in about a thousand rounds. Many of them being cheapo Russian stuff and a lot being with the can on it. ARs need to be oiled not necessarily cleaned.

Thanks! As I suspected, it looks to be the ramps. On mine, you can see where the sharp edge of the right side of the left feed ramp has a good deposit of copper.
