I ordered this part from Bushmaster (www.bushmaster.com/shopping/gunsmith/imp-1.asp) and it arrived today, but I absolutely cannot figure out if it's made out of delrin plastic or not. It feels pretty light so I assume it's delrin, but does anyone know for sure?

Thanks

My new Oly 9MM upper is such a tight fit with my MEGA lower, the rear pin can only be inserted flush if I use a punch and hammer! Getting it back out is the same thing.

I may need one of those until it "works loose(r)" I've got a couple uppers that fit extremely tight. Only one can the pins be pushed in/out with ease using only fingers.

ammo works as well to push the push pins.

The push pin is not complete until you also get some of those really long pipe cleaners for your gas tube.

It's a niftly little tool, but as long as you're careful you can do it without the tool. It wouldn't be a bad idea to make sure that you've got it pointed in a direction so that you can find the spring and plunger just in case.
