I've been unable to find an LMT S/A BCG to complete my build but have found a retailer with a F/A version in stock. Are there any problems using this in my S/A build?

the heavier F/A M16 BCG is usually preferred over the Semi carrier. I have two BCM F/A BCGs and an LMT F/A BCG in my rifles, not a hiccup.

I wouldn't use anything BUT the F/A... even if I had to wait to get one.

These are the weight of BCG that Eugene Stoner originally designed this rifle to use. Each derivative of the semiauto version became lighter, causing greater and greater compromises in functional performance.

Now that installing one in a non-F/A has been decriminalized they're the only way to go.

Can I ask what the reasons are behind that? I've heard a few people say that, but I'd like to know why. Is it because you can run a standard carbine buffer and get proper operation with most ammo? FWIW, I use the F/A version in all my carbines because it seems to be recommended.

Or...I could search :)

It's the next best thing. It all depends on how patient you are willing to be. LMT now or wait for BCM.

It's the original and correct part for one. The carrier cocks the hammer for two. On the emasculated carriers the firing pin cocks the hammer. You get more retaining pin damage and such.

The weight has nothing to do with it for me. If I need more weight, I'll change buffers. I have guns that run like champs with the wimped out carrier. But if I'm buying/building something new, I always go with the correct and original part.

Looks like I lucked out finding the F/A version of the LMT.

Out of curiosity, why is the BCM more desirable than LMT?

Thanks. That's what I was looking for.

Another reason is downstream compatibility.

While I don't yet own an M16, I will eventually. This way, all my uppers will interchange. Every one is ready to go.

God bless Stag for making a Lefty M16 bolt carrier to go with their lefty upper. ;)
