I have heard that doing this is difficult on the Colt because of the metal the use, I hear it cracks easy.. Anyone shine some light on this for for me or am I just being a wimp.
New owner of the Colt M4 OPS! I got a bunch of 20 round mags for it, cause those 30's are too big and in the way! so far I have a Bushnell TRS-25 on there with some Magpul extras..XTM covers, MBUS rear sight, MS3 sling with ASAP, and I have the MIAD grip coming in today actually! (gonna get my dremel on).
