View Full Version : LMT Enhanced BCG w/ 14.5" mid length question
Question for those who have used this combination. I have read on several forums that these carrier groups are meant for 14.5"/16" carbine barrels and that you shouldn't use them on a mid length setup. I'm not going out of my way for one but I already have one from another upper that I was planning on using with my 14.5" BCM upper that arrives tomorrow.
Will I be okay running this bolt in my new upper? I really don't want to sell it and I don't want to spend the money on another bolt carrier. Anybody used this with success or failure? If not I guess I'll try and trade it for a Spikes or Fail Zero NiB BCG.

I'm not sure if it will work but you could just buy a new carrier for 50-70 bucks since you already have a kick @$$ bolt.

Edit: Sorry. Responded before reading your link.
Swapping the carrier is a great idea that I didn't think of. I didn't realize that one little extra port made all the difference as far as the gas goes.
It's not just the port. The cam pin track is different to delay unlocking. The LMT enhanced bolt carrier is intended to offset the long dwell time of a car gas 16" gun. A 14.5" middy is a more delicate balance than more conventional combos. BCM has theirs worked out. I think it would be best to use the parts they chose.
I didn't get that memo. The AR on my avatar has a Noveske 14.5" middy running LMT enhance BCG. Two tac classes later and many trips to the range, all good.
Good enough for me WETP!
Thanks! Thats why I was looking for first hand experience with running it on a middy.

Stay with the lightest buffer possible and only use full power 5.56 ammo if you are gonna try an LMT enhanced carrier in a 14.5" mid length upper.
I can just about guarantee problems with that setup if you use wolf or pmc ammo and a heavy buffer.
