Mag blocks in MA?

[greencobra]

My M&P 15-22 came with a blocked 30 round magazine.

yeah, smith uses blocks in their mags. at least they do it in the m&p .22 pistol to make the 12 rounders into 10's. and i don't know if i'm telling tales out of school but the blocks are not permanently fixed, they will come out if desired.

Old thread revival - buddy ordered a P320 to his FFL in Littleton, came with three 17rounders and the FFL 3D printed some mag-blocks for them to limit them to 10 rounders. Did not epoxy the base however. Choose your own adventure indeed, interesting option here since he never possessed them in their illegal 17 round form before they were transferred to him via an FFL.

What store in littleton, would love to see if they can make a sig p365 one.

How hard is it to disassemble the magazines?
