GUERILLA POLICE MAGAZINE VALVE BODY W/ O-RING

Valve body assembly for the KWC PT92 / GUERILLA POLICE that does use this valve body setup. Here and there, there are POLICE models that uses the assembly that the SNORRE and GANGSTER uses.

These are original KWC drop-in replacement parts and requires no modification to your magazine.

Just use an O-ring pick or its likeness to remove the O-ring inside - use a flashlight to spot it inside if it might appear concealed.
We recommend flushing the valve chamber out w/ BALLISTOL universal oil and swabbing it out by way of a twisted piece of cloth. Twist said cloth in hard and keep pushing in whilst rotating to swab out as much foreign debris / dust as possible.

We also recommend dabbing rubber grease on your O-ring and you can apply some to the white PTFE seal on the valve assembly too. 
Be sure to install the NBR O-ring in properly by assisting it w/ your O-ring pick as appropriate.

As for the valve - you'll need to modify a sizeable flat drive screwdriver. This will be to thread the old valve out and to thread the new one in. Tool tight is the way to go - don't tighten to the extreme and run the threading out.
