I was wondering if someone could guide me in taking down the  MP9 bolt. I have a large crack in my cylinder and to replace it, I have to remove the pins at the back of the bolt, so it seems. However hard I hammer on the pins, they won't budge at all.. Any tips from anyone .. Info is really appreciated.

Thanks guys.

You need to remove the little reset block with a 1/16in punch before the two tension pins can be removed.  The solid pin that holds the reset block has a spline and must be removed from one directly only.  So you need to find the correct side before you drive it out completely.

Any chance for some pictures? My cylinder just completely blew apart, not sure why, though I have a feeling it was because I was dry firing it a lot. Still snow here so I was screwing around. I assume this is not a good practice.

That's what you get for dry firing it in your living room instead of playing airsoft with us!

Alright alright Dobes...

If it's still crappy on 3/5 I'm still coming.... I can't take this anymore.
I was unaware that I had to have the gun cocked to insert a mag. I thought that was only the case with the M11.
I ordered 2 cylinders just in case.

Just with the Mac, it's a carry-over problem from the first generation design.

:P but do avoid dry firing, it's a poor practice in general.
