NO because:
1. MGL references the Federal AWB for definitions. (Think symlink)
2. Supremacy Clause
Isn’t this the definition of AW pistol?
Semi-automatic pistols with detachable magazines and two or more of the following:
1.Magazine that attaches outside the pistol grip
2. Threaded barrel to attach barrel extender, flash suppressor, handgrip, or suppressor
3. Barrel shroud safety feature that prevents burns to the operator
4. Unloaded weight of 50 oz (1.4 kg) or more
5. A semi-automatic version of a fully automatic firearm.
Assuming this SBR is on a normal lower... won’t it violate #1 and #4 at the very least? And more than likely 1,2,3,&4.
not that anyone really cares, but I find it shocking (not really) that registering it as a handgun is like admitting you are breaking the rules. This state just sucks for clarity on gun laws.
