A question for the airgun educated

[JMG]

I was just sittin here thinking and I blew up.... no just kidding. I was wondering if anyone has seen a plastic lined receiver in a spring piston gun? Like maybe a ptfe,delrin,polymide etc. My thinking is if it were used inside the receiver kind of like a low friction slippery deal, then maybe when the compression chamber is sliding back and forth during cocking it would make for a smoother cocking action? I know that us B3 owners have some issues with the sad tolerances between the receiver and the compression tube. We all hone,sand,stone hehe grind the receiver to make the compression tube slide smoother. But wouldnt it be nice to have a slippery teflon surface for that compression tube to slide back and forth in instead of metal on metal? Just a thought lemme know what ya'll think.

Interesting thought... I wonder how hard it'd be to do that?

I was thinking the same thing about the rough feeling/grinding during the cocking cycle on the B3's. I was thinking of using MolyFusion inside the reciever and compression chamber after being honed & polished. Also in the barrel.

There are 2 members at rimfirecentral.com named ToxicSports and Skeeter27Red that have used MolyFusion on rimfire rifles, Airguns, Engines and have nothing but good things to say about it. I believe it was Skeeter27Red that used it in an Airgun barrel and gained something like 15 FPS after the treatment. He shot a full tin of pellets to make sure it wasn't dieseling. He also said accuracy improved a small amount.

Now I figure if I use this in the reciever, the cocking cycle should smooth out a bit. Treat the Piston & Compression chamber, then they'll be slicker than pig snot. Maybe even the spring? And then the barrel. Reduce as much of the friction as possible and hopefully it smoothes the rifle out, increases FPS a bit and makes the rifle an all around better shooter?

here's a link to the MolyFusion:

Sam.. I don't think that is the answer..:) But go ahead and try it out and get back to us..:)

I don't think so either Gene... But, I don't think it could hurt anything though. I figure it's worth a shot!

I went to the Dupont website trying to expand my education a little on teflon. Apparently you can powder coat ptfe. So then I started thinking to heck with the receiver, powder coat the outside of the compression chambers of springers with a heavy coat or coats of teflon. Then the receiver can be prepared for the compression chamber and the 2 could be a nice close tolerance fit. Of course this onlly applies to lever cockers I am assuming. And of course the only lever cocker I have is the B3 so that is what I am basing my thoughts on. Hehe it would be nice if Wally world sold a can of stuff that you could spray on and it would harden and have that slicker than ice on ice glide with good abrasion characteristics.

I remember there was a Spray for fixing Nonstick pans. You sprayed it on and then baked it for 45 minutes at 500 degrees. It was supposedly a black teflon coating. I remember me & my dad talking about using it on Undersized Miniballs for out black powder rifles. We never did get any though.


I wonder if it's still around?

Basically thats the prob Sam the stuff from dupont you can get is in a powder or liquid form but... you need like a powder coating setup to do it. and the industrial oven to cook the junk.
