Airsoft Canada - View Single Post - Hi capa Standard Division build problems- Weak blow back, not cycling completely

So i recently started to build a standard vision Hi capa from the the ground up using Airsoft Masterpiece complete SAI slide kit and frame. However i'm running into weak blowback issues. The gun only cycles half way and doesn't allow the hammer to engage all the way.

Its definitely not the upper assembly since i tried it on another frame and it works properly(there isn't much there that could affect it honestly other than the nozzle and blow housing assembly and piston). I've checked the inner parts and the sear, valve knocker, hammer, valve reset, and disconnector seem to all work properly (as in it does engage when i manually pull it back and releases, as well as resets the trigger). It just doesn't cycle all the way when its actually being fired.

Any ideas what could be the issue?

Currently using a guarder 150% recoil and hammer spring with shock buffers. Frame, valve knocker and sear and Airsoft masterpiece and the hammer is UAC with a nova hammer strut.

Any help would be much appreciated. Thanks!
