Upgrades Req'd for KSC USPc on Propane

I've done some searching, and most threads ssay metal slide, but stop there.

What else should I do to get the gun ready for propane?

I was thinking Metal Slide and a stiffer (possibly 150%) recoil spring.

Anything else?

Thanks in advance.

You don't need to get anything. Just do this mod and you're good to go!

Mine's been going strong on propane ever since!

Edit: if you read the whole thread you'll see that you don't even need to buy an O-ring, just flip the piston cup around and voila! Propane ready!

Accepting my stupidity, which part number is the piston cup/seal that I am reversing?

And thanks!

I forgot... I think it was #28 but basically when I did it I just took it apart and it's pretty obvious which one when using this site as a comparison:

Thanks man!

Got it flipped. The kick on it now is insane. It keeps knocking the litte clip on the right of the gun off!

The FPS is up (as far as I can tell...going through material it couldn't before), and MUCH more accurate.

Still feels like it kicks too hard for a plastic body, but if others have been okay, I can only hope for the best.

Plus, (one of the reasons I bought this gun), there is many replacement parts available.

Thanks again.

Here's the best upgrade you can do. Find a HK retailer/distibutor and replace that friggin cheap cheap cheap ass monkey metal garbage trigger with a REAL USP Compact trigger.

Takes minor fitting to install and it WONT BREAK! Unlike KSC's el cheapo crap.

I personally advise trying to fit as many REAL parts as you can to your guns, as airsoft companies make generally piss ass quality crap.

Glad you found it.
Yeah the kick scares me all the time but its also one of my favorite points of the gun

Thanks for hint BC.

dontask:

How many rounds have you put through it with propane like this? Still no plastic slide breakage or anything?

I've used propane from day one even before I flipped the piston cup.
I'd say upwards of 1000 rounds have been put through her and as far as I can tell it's in the same condition as when I received her.
