Just posted this in the pistol thread, but thought id expand a bit here.
First attempt at building a glock, thought I'd go with a more..."stock" approach first. Got it tuned to fire 43 shots from one gas fill of propane, shooting about 300-310. Almost everything has been swapped, running:
TK Twist inner barrel
Nine ball hop up
PGC slide and threaded outer barrel
Guarder frame
UAC Day/Night sights fiber optic/tritium
Airsoft Surgeon hard Nozzle
Guns modify lightweight bbu housing
Guns modify STD trigger
Guarder parts thrown in for good measure, recoil spring, slide lock, slide release, hammer spring, base plates ect...
Shooters design parts such as hammer sear ect...
Sequential Airsoft's Silent Fill Valve o-rings
So far she runs great, and honestly its one of my better preforming pistols, even tho I was reluctant to get a brick shaped gun at first
Wasnt as much modifying as I thought it would be, some filling had to be done to the hammer sear and front sight, and I had to spend a bitch of time getting a screw to connect the piston head to the piston in the bbu housing.
