OK, so i have read all i can find on Pneumags, but i still need some advice. I have a y framed mag that i want to make pneumatic. I know it can be done, but i have read that it can be more challenging. I have an EP milled rail already and i want to run my lpr up front under my barrel, hints the milled rail. Do i have to drill and thread the extra hole in my veritcal asa myself or do they make ones with a front hole in them already? Also, which LPR should i use, i want something on the smaller side but also good for a pneumag. Also any advice for the y frame setup would be awesome as well. The info on this set up seems to be limited. Thanks in advance. I look forward to soaking up all the knowledge of the experienced maggers on this forum.
