I like guns that are different but functional. I had a Bushmaster XM-15E2 that wasn't committed to any other project so when I found the TAC2 website and looked it over I ordered their kit and put it on the Bushy. It resides in a briefcase and there is room for a red dot/laser sight with a QD mount or you can leave a holosight on. It is very quick to assemble and fits well. I had a chance to take it to the range and it runs like a dream after a few minor adjustments and tightening evolutions.
I can say this is a neat setup. Regards, Al
