LWRC M6A2 FTF

I just got a new M6A2 and when I hit the bolt release on a full magazine the round doesn't feed properly, locking up the rifle completely. The bullet sits partially in the chamber at an angle while the bottom of the brass is still in the magazine. It then is almost impossible to get the round free. The charging handle and the magazine release are both locked up, takes a lot of muscling to get it free. However, when I load a magazine with the bolt closed and charge it there are no problems. Anybody had this problem and/or know a solution? Thanks.

It really sounds like a mag issue, what kind are you using?

I second the mag problem. with the round in contact with the feep lips (as in a bolt open) the round failed to feed. I assume you mean with ONLY a full mag. The spring tension and friction of the feed lips is enought to grab the rim of the case. But when the rounds are pressing against the bottom of the bolt carrier there is some movement of the top round that lets everything go right.

Check for notices at the end of the feed lips inside the mag.
Are the feed lips bent open, shut or worn out?
Is there enough lube in the upper?
How old is the buffer spring?
Is the buffer the correct weight and style for the rifle?
Is 29s round good every time?
Are the rounds at the back of the mag?
Is the chamber free of problems?

Other FTF problem areas.

I'm using P-Mags. And yes, the magazines were full. I only ran 90 rounds through the rifle (my first and only time I've had it out). I'll try it with 20 rounds loaded next time and see if that makes a difference.

Did you try several different magazines? Run the gun some and see if the situation improves. The bolts in my LWRC were a little slow for the first 100 rounds. They wouldn't chamber my reloads properly, although they made it into the chamber 90%. After 100 rounds or so the bolt seemed to break in a little and I had no issues. Just another thing to try.

1. Cleaned and lubricated rifle? CLP, not grease? The bolt needs lubrication as does the cam pin.

2. Magazines can sometimes have an extra round jammed into them and that condition will produce the failure to feed you're experiencing. Skip the plastic magazines and get some USGI magazines until you're confident the rifle feeds properly. Top round should be on the right. If it's on the left the magazine is either under or overloaded. Ya can't get two extra cartridges in there.

3. Tripping the bolt catch (note this is not a bolt "release") does not give you a full spring stroke for feeding. Rarely has problems, but retracting and releasing the charging handle gives just a little more stroke.

Someone recommended to me to use P-Mags with 28 rounds. Always have and never had a problem.

30 round magazines that only function well with 28 (or 29) rounds are not good magazines...

Magazines are expendables. If they're not working discard them for working magazines. While not normally available in designer colors, the aluminum USGI magazines have provided me decades of reliable service. For easier handling I strongly prefer the USGI 20-round mags.

The only reason to download good magazines to to carry less ammo....

I have three LWRCS. The magwells are tight. Try using the M version of the PMAGS, the ones that the top clip can clip on the bottom of the mag. Those are good to go and can be loaded to the maximum. The older PMAGS were too tight in the magwell and had to be downloaded a few rounds.

My Magpuls also work fine with 30 rounds. Unless its a zombie apocolypse, 2 rounds shouldn't make a diffence between me living and dying, If it does, I need alot more range time.

My comments were intended for folks who carry and depend on these systems, not plinkers who can carry as much or as little ammunition as they want.

Damn those hobbyists!
