I'm considering the purchase of the LMT Enhanced BCG to upgrade the stock BCG on a Colt SOCOM - 14" barrel, etc. But I was confused by the option of choosing a full auto over a Semi? I should mention that I am planning on a suppressor for it and wondering if that makes any difference or would impact my choice.
More generally, let me also ask if a LMT Enhanced BCG is a wise move to assure additional reliability of the M4?
Thanks.
What do you mean by "to ensure additional reliability"? Are you having problems with the Colt bcg?
Get the "full auto" M16 version. There's no reason to go with the "semi auto" AR15 version.
This. Because I think the extra weight is a good thing. But I’ve never weighed them both to see the weight delta. Also, I’m. Not sure if the BCG’s have changed since this time.Quote:

It’s possible to come up with an original inquirer based on a new product but for age-old questions like yours - there will probably be a thread to two.
There is some time and effort spent in developing that BCG. I use the enhanced carrier and standard or Sionics bolt in my SBR’s.
However did you search M4C??
If you didn’t your question is addressed here:

I have an M4A1 SOCOM. I have an LMT enhanced BCG.
You MIGHT see a small improvement by installing the LMT. You might not.
Having put both the SOCOM and the LMT BCG through their paces, I would not put an LMT BCG in the SOCOM. The SOCOM doesn't need it.
If you did put the LMT BCG in the SOCOM, you would also need to adjust the gas port to see any advantage the LMT BCG would give you.
Take the money you would spend on the new carrier, buy ammo and go shoot it up this weekend on Veteran's Day.
Before I get into LMT, if you are not opposed to spending $330, then maybe look at the new Surefire bolt/carrier kit:Quote:

I have a few LMT E-BCGs but I am not an expert. I ended up with both a Full and Semi. And they weigh almost the same, I think. My S/A was 9.00oz but I cant find what my F/A weighs. If you are buying new, then get the full auto.
Remember this is a system, if you add the LMT enhanced carrier you will need to address the faster bolt speed. If you add the e-carrier AND suppress, then you are adding 2 things to speed up the carrier. The faster carrier speed caught me out, I thought years ago that it slowed the carrier.
I use them on suppressed setups with heavy buffers. One has an adjustable gas block 11.5 and the other 12.5, has a smallish port.
I have a Colt M4A1 F/A for 10 years and thousands of rounds and have never had a failure. Not sure why you would spend additional funds.
For your application, the LMT E-Carrier Group isn't going to do much.
What’s wrong with the Colt BCG? The answer is nothing. You’re literally wasting money. Spend that on ammo, optics, mags, or training.
I thought the LMT EBCG was designed specifically for the 14.5" M4? Not that the Colt BCG comes up short or anything, just that the OP's barrel length is what LMT designed it for.

Is it overkill? Perhaps, and certainly pricey. I have two in carbines and two more in storage. I like them, and if you have the $$$ go for it. That said, if your budget is tight the Colt BCG should do just fine.
