building AR uppers with pre-ban features

[SnakeEye]

Is it legal to build, own, and store an AR upper with pre-ban features so long as said upper is not attached to a lower reciever?

Of course it is legal*, why wouldn't it be? Evil uppers are perfectly legal to own, build and store. Hell you can even install them on "pre ban" guns or registered M16's.

Probably wouldn't be the best idea to have one if you ONLY have a "post ban" lower, but honestly I have never heard of anyone facing a "constructive possession" charge for AW issues.

*just don't build one w/ a barrel under 16 inches, unless you have an MG, SBR, pistol lower, or no lower at all, cause installed or not you could run into "constructive possession" issues.

During the Fed Ban, BATFE position was that it was:

- ILLEGAL to possess a pre-ban upper, IF you ONLY had a post-ban lower (or post-ban gun).

- LEGAL to possess a pre-ban upper, IF you HAD a pre-ban lower/gun, even if you had post-ban guns/lowers TOO (ADDITIONALLY). This was true as long as you did NOT assemble said pre-ban upper on a post-ban lower.

MA has NO SUCH INTERPRETATIONS (above were usually letters from BATFE Tech Branch) and NO TECHNICAL ABILITY to issue such letters to MA Residents! So, you're "on your own" and a frisky DA/PO can make your life miserable. If you hire competent counsel you can probably beat the rap (assuming you fall under the 2nd case noted above), but you'll lose thousands of dollars (or more) to do so.
