The $200 Tax Stamp only pertains to the transfer of a registered short-barrelled rifles, short-barrelled shotguns, suppressors, or full-auto firearms. It will not apply to you building your own AR15 rifle as long as the barrel is at least 16" long. You will not be able to buy a select-fire capable receiver.

This tax was established by the National Firearms Act of 1934, and the amount has never gone up. Hope they never catch on to that...

If you can wait a couple of months, we will be rolling out our AR15 lower receivers which are machined from an aluminum billet.
