Well it's ugly, cheaper than a 9mm AR. Olive green stock, And uses glock mags, it has ghost ring with nightsite front and have had fun breaking it in on groundhogs 50yrds or less.
I really want to use some of my 125 penta hp/135 gr flatnose from my coveted miha 9mm mold. ACWW lubed with tac-1 sized @.3575. My bore is .354 I am considering using a plain base gas check with Blue dot or Unique. Made a dummy up and it feeds from the mag. Could not find any ruger specific posts in the search. Am I going too far or will it shoot without the check and not lead? I wonder if it has enough lube groove volume for the 16 inch barrel and 200-400fps higher speed without a plain base check? You folks always are a big help !
Thanks
