I have a M4 that I just ordered. I installed the full length mag tube from SOCOMGUY as well as the skeleton stock. Looks great right? Well, before I went to the range to test fire this beauty, I wanted to see if it cycled properly (figured I wasting my time, but what the heck).
Well, I filled the mag tube with shells. When it was time, I pulled the bolt back in one swift motion and let go in order to load the shotgun. To my suprise, the shell was still in the bottom area resting on the feed ramp that guides it to the barrel. The shell was resting perfectly horizontal on the feed ramp. The bolt "seemed" to be locked back. I was like, what the heck.
Then, with the slightest (and I mean slightest) touch, I touched the bottom of the feed ramp with my index finger and it snapped forward with authority and I was good to go. The gun was loaded. Just like a 11-87.
I tried cycling this shotgun several times and got the same results again and again and again. Is this normal. My M1 Super 90 does not have this problem.
I disassembled the shotgun, wiped it clean, re-lubed it, and reassembled it. Still have the same problem.
Oh, and when I rolled the shotgun to its side, the shell suddenly loaded. Like it is just a hair away from functioning properly. I just can't put my finger on it.
Any answers? I will try to get pics up
