Failure to Feed Last Rounds on LWRC M6

[SkinnyGrey]

I am having trouble with the last few rounds of my LWRC. Most of the time the third to last, second to last or last round fails to feed. I have used several different magazines ACS and Bushmasters. I have had more luck with the Bushmaster mags but the problem has even happened every other magazine with the Bushmasters. I used two different ACS magazines and I believe it happened every time with them. I am using 6.8 Remington ammo (110 gr I think). the gun fires flawlessly until the last rounds of the magazine. I did have a new stock put on recently, but I'm not sure that would make a difference.

I am thinking of sending it back to LWRC but I'd appreciate to hear people's thoughts on here first.

Many thanks in advance.

you have not spent enough on your AR (joke) you must not buy such a cheap one (joke). sorry to hear that you spent plenty on that rifle and it should cook you breakfast. when you say failure to feed how do you mean? if the round is not going in the chamber after numerous shots it sounds like chamber might be to tight heating up and expanding. it sounds like something is heating up on you and changing dimensions. no one can blame that on the non existent problem of lacquer melting off "cheap" steel cased ammo. ltry gently cleaning up the chamber with a drill and brush.like to know how it works out
