I've got some serious leading in the barrel of my M4. How do you like Kroil? I've read soak the barrel and let it set overnight.

Thanks. Will do.

To summarize. Bolt in battery. Insert snap cap/shell into magazine. Depress cartridge release lever. Sometimes the shell is moved into the magazine loading port. Then I cycle the bolt and the shell inserts into the chamber. But, sometimes, with the bolt is in battery. I insert shell into mag. Then depress cartridge release lever. Then, sometimes, the shell remains in the mag, and when I cycle the bolt, the bolt simply locks open. I can follow the same procedure but get two different results. I tried to edit my OP but can't seem to find that option.

I bought it used but it looks new. I fired a few rounds just to prove the weapon. But I seem to be having some issues with it. For example, I can cycle the bolt a few times. Then, with a snap cap in the mag, I can depress the cartridge drop lever, hear a small "snap", pull the bolt back, and the bolt locks open. But then again, I can cycle the bolt a few times, insert a snap cap in the mag, depress the cartridge drop lever, and instead of a small "snap", I hear some substantial mechanism snap forward. Then when I cycle the bolt, the shell carrier moves the snap cap into the receiver and the bolt seats it into the chamber. I can perform the exact same procedure any number of times and I have no idea which of the above movements are performed. What am I missing? Is it a malfunction? Or am I doing something I don't realize? I'd like to consistently be able to depress the cartridge drop lever, have the internal mechanism snap forward, pull back the bolt and load a round.

Two posts above yours: "My friend put one on his MAC clone and likes it. I was avoiding it solely because I don’t like how much work it takes to take it off for cleaning and put back on." You have no problem with the above inconvenience?

This one from MidwayUSA for $183?

It's for a metal "tab" that extends from under the forearm to cover the bolt release button. It makes it easier/faster to close the bolt. thnx

It's got this stock and slip on recoil pads won't work.
