AR-15 Vice Block STURDY!!

Print this at 90% infill, print on its side for maximum strength.

Nut and bolt holes included in design to allow crushproof clamping, at lower infill choices.
If printed at the 90% no N/B needed as the print is a solid block, and should not crush at all.

Either way at any infill desired, this design should last the test of time...
