Since it’s a factory SBR, I don’t believe you can just pin a flash suppressor on a 6921, not with the original lower receiver.
It would still be in the NFA registry.
If you guys hate a 16" barrel that much, do what other’s have suggested, buy a 6920 and then get a Colt 14.5" barrel or an entire upper and pin a flash suppressor long enough to make it to 16".
That’s a whole lot of expense to go for and only drop 1.5".
What are the pro’s and con’s of having Adco cut down the 6920 barrel and pining an extended A2 to it vs. trying to find and then pin a 6921 barrel?
What’s the difference in buying a 6921 or buying a 6920 and then sbr-ing it?
You are right. I forgot about the lower already being NFA.
I don’t hate the 16"I have one. I just wanted a real M4. You are right it is a lot of work just for a 1.5".
Thanks for clearing that up.
Correct me if I’m wrong, but while Federal law supersedes State law, just because Federal law classifies it as an “SBR” doesn’t mean that Michigan state law will. For example, Michigan state law classifies PS-90’s as pistols and therefore all state pistol laws apply, not rifle laws. My question is, does Michigan state law expressly prohibit Federally-labeled SBR’s, or simply barrels less than 16" length? If the latter, then you COULD own a Federally-registered SBR lower if you re-registered it with a 14.5" perma-pinned barrel.
Again, that’s simply my conjecture based on logic and it could be wrong. Even if right, that’s still a lot of hoops to jump through.
You’d have to have someone do the engraving work on the receiver when you SBR a 6920. The factory SBR’s – 6933’s and 6921’s, already have this done, at Colt.
I’d highly suggest taking a look in the NFA section here on the board for more in depth answers about Short Barrel Rifles.

I tend to agree. I’ll probably just buy a LE6920 and leave it alone. I do think that the 14.5" bbl looks much better than the 16" though.
It looks like more of a difference than just 1.5 ", but it isn’t.
When comparing the pictures of the LE6920 with the M-4 at the Colt Defense website, maybe the longer magazine in the M-4 vs. the shorter mag in the LE6920 make the bbl. difference look greater.
If the seller is willing to deregister the lower, then yes, you can. That’s what Ken Elmore at SAW does with his LE6921 “Special Edition” rifle. Ken does his “reliability package” as well, so there is some value added. Whether it’s worth it, each buyer has to decide.
I bought one on a whim and I’m pleased with it. Dead nuts reliable, and very pretty to look at. I’m building a small Colt collection, and I wanted the rollmark without the tax stamp, so it met my needs.
But from a purely functional point of view, you can get the same effect for a lot less money.
Clyde Armory sells deregistered 6921 lowers, if that’s what floats your boat.
