Bolt grinds when pulled back

I recently have upgraded my UTG L96 with

Angel Custom Type-96 MAX Stainless PTFE Cylinder
Action Army Specialized Trigger Kit for Maruzen Type 96
Angel Custom Advanced PSS2 APS Type 96 Precision 100% CNC T7075 Aluminum Piston
Angel Custom APS2 Type 96 First Factory PSS2 Stainless CNC Steel Spring Guide w/ Ball Bearing (7mm and 9mm)
Angel Custom PSS2 Power Accuracy Piston Head
and a M150 AA spring

After installing it all, my trigger box pin was very hard to get in and out. Now when i pull the bolt back it grinds and is not smooth like it should be. Everything has been properly lubricated using the correct oils. I was wondering if anyone else has had this issue and if they know what the grinding could be.

My guess is the trigger box pin is not gliding in the cylinder correctly, but im unsure. Any thoughts or advice would be appreciated

I agree, itīs probably a triggerpin - cylinder issue.
Open it up again and you should be able to see wear on these pieces.
Maybe your pin is not perfectly perpendicular to the cylinder, or it is just to wide.

Also, donīt buy anything from angel custom!!

what would be the best way to fix the issue if that it ? to sand down the trigger pin to have a better fit ? or something along those lines?

Also what is wrong with angel custom ? im new to airsoft and still trying to learn/tech guns and ive been going off other peoples recommendations on parts.

The trigger pin I guess you are talking about is the spring guide stopper and also the trigger sear as that will most likely have the same issue.
Either dremil the slot that they fit into a little wider or file the sides of the spring guide stopper and the trigger sear just the smallest amount. You should be up and going then.
