Well I got the M4 today and opened the box and noticed all the oil had leaked out of the container. I was a little surprised that it was all broken down, I thought it was going to be complete. No big deal, it actually made it easier for me because I added a factory collapsible stock and then had to make the dam thing 922r compliant:rolleyes:
The installation of Kip's full mag tube was fun (seriously). Placed the receiver in the bench vise with rubber guards, fired up the old heat gun, put on my work gloves and it came right off. I was surprised how "little" heat was needed to melt the factory locktite . I'll bet I didn't even get it up to 130 degrees if that. I thought you had to really get them up to 250-300 degrees. I would heat a little then try it and keep doing that till it came off. I liked that little tool he throws in there to get that red cap off too. Piece of cake.
Now for my stupid questions. I noticed that it came with a factory "choke" in the barrel. What the **** does the choke do? Do I really need it in there?
The manual shows different ones with numbers on them but my has no numbers on it. What's up with that? Is it supposed to have numbers on it?
