CaliPCC Posted February 9, 2019 Share Posted February 9, 2019 Current build parts: - QC10 receiver set and bolt (weight not removed) - Taccom 3-stage PCC Buffer assembly with rifle spring (spring it came with) + Short stroke kit - Standard mil-spec buffer tube carbine length - KVP 16" barrel and KVP linear comp - Taccom CF handguard - Strike Industries Viper CQB stock - Hiperfire Reflex trigger - Using factory ammo (currently winchester 9mm 115 and 124gr, will experiment with different types soon) - Using 10rd (California) Glock OEM and ETS magazines Issues: - Castle nut gets loose after about 50 rounds even after proper torque - Quite a bit of recoil and muzzle rise, would like to shoot flatter. Double taps are far apart. - Out of the ~400 rounds fired have experienced a handful of failures to feed, I'll blame the new stiff magazine springs.. Considering: - Changing the buffer spring to a Taccom 308 Carbine spring - Replacing the buffer tube (need suggestions) - Replacing the compensator with Taccom 2 port short compensator to direct gasses upward - Wondering if the lightweight CF handguard is contributing to the muzzle rise - Wondering if the stock is not gripping well, experiencing muzzle rise no matter how good of a cheek weld, grip and stance I have. Various shooters also experience issue. Wondering where I go from here, overall its a very fun gun, just trying to optimize it for competition and maximum enjoyment and hoping for some good feedback from the community. Many thanks in advance. Quote Link to comment
