Solid (almost 8oz) and very durable- my friend used one for his build and now uses it as a spacer between his floor jack and truck frame! You could give it to mom or a female family member to put in a gym sock as a personal defense weapon to whack somebody over the head with (just sayin’, but not 100% guaranteed)
Note: this does not work on the AR-10 platform. I have vise blocks coming shortly which I will be keeping in stock.
I have upper/lower vise blocks that I sell for $18 but the “vise block combos” sell very quickly.
