I "need" / want a tree for rimfire, I have a AR 500 3/8 x 6" paddle tree but the .22 doesn't budge the paddles.. I figure I can pull the paddles on the tree and drop in a thinner paddle.. Question is should I go with the A36 mild steel at 3/16 thick or gamble and go AR500 1/4" thick ? My brain cells say go with the mild steel 3/16 for the lesser weight factor.. Will a .22 even budge the 1/4" ??
