So here is my MR 1 with lots of DIY stuff - its pretty much awesome. still in the mail is a laser that attaches to the barrel and I am thinking about a G2K hopper - i don't want to go electro and it is the best looking gravity hopper out there. also i am thinking about getting an air-thru stock of some sort. question for those who have the RAP4 flex air stock - does it interfere with your mask?
