Multiple NFA questions

[Pappabear]

I have a friend that just bought a BCM lower and is putting on a SBA brace to make it a pistol. Can you do that or do you have to buy it as a pistol lower?

If it is a pistol lower, can you put a barricade brace on it? Or is that like a VFG? and a no no ?

How heavy would a Surefire RC2 7.62 can feel on a 11.5 BCM? I would think hefty to me but want others thoughts.

Would you just stamp it and say Eff it? Or try the pistol route?

I have stamped all my shit so I have not kept up with this pistol non-sense.

Take this with a grain, but my understanding is that as long as the lower has never had an upper put onto it (meaning, not sold as a complete rifle or assembled into one) at the same time as a stock, you can rip the telestock off, slap an SBA3 or SBA4 on and you're ready to rock. Until they ram the "rules change" through anyway... generally it's recommended that you add length-of-pull limiters to match how the SB A-kit tube has position 6 either blocked or completely unmachined.

If the lower was sold as a rifle, it will still be a rifle even with the brace. If used with the 11.5" it would be a SBR. If it were me, I'd just save the rifle lower for future use and buy a braced pistol lower.

I don't find a RC2 on an 11.5" SBR objectionable.

how the SB A-kit tube has position 6 either blocked or completely unmachined.

I think the SBA4 shipped with a standard six position "mil-spec" receiver extension. Are you referring to something else or is this new?

If the lower was sold as a rifle,

A lower is not supposed to be sold as a rifle. This is why you cannot buy one at age 18. There are multiple threads on the subject. Here's a quote from the first one search turned up.

Lowers should be transferred as others. It's been that way for a long time. Once you have said lowers, it may be assembled how you want. Your state may have certain requirements, but as a rule lowers marked pistol are nothing but a gimmick.

Perhaps I'm misremembering, God knows it happens more often than I'm comfortable with especially in a profession rooted in data storage/retention/retrieval--I thought at one time they were talking up how they had cut their tube for milspec compatibility but ATF required some limiter on LOP.

They sell LOP limiter inserts but the brace kit does not come with any as far as I know.

^^^This. It is an "other". Transferred onto their books from BCM as such and out the door as such. Only way it would be a "rifle" would e if the LGS received it from BCM as a rifle and then split it up and sold it separately.

IIRC the standard receiver extension meets the LOP requirement, the VLTOR A5 type are the ones that are too long. But at this point in history how much these petty "rule" interpretations matter is going to be debatable, IMO worrying about coloring a little outside the ATF imposed lines is a waste of time.

+1. There are three types of guns that get transferred; pistol, rifle and other. Other is a receiver or frame.
