"The cylinder head threads are too long; it bottomed out on the cylinder threads, so I had to use my stock CH. On a positive note, the polymer bushings on the piston are great and removed the tough bolt push I was having with my old Angel piston. "My Ctac vsr-10 developed the slam fire we all know and hate. So this unit looked to be a decent choice as I wanted to upgrade my piston as well. I still don't think 5 days to pick an order is acceptable, but what have you.
This unit came shipped with everything I needed to back into my vsr-10. Took apart my rifle, removed the old trigger and the Alpha fit directly on without any issues what so ever. When it was time to drop in the piston I did have to sand away a decent amount to the delrin bushings to get the piston to slide freely on my cylinder otherwise the piston would stick. Once sanded it went together perfectly. Put it all back together and presto, time ti try it out.
I am using a 130 sprint and was getting about 420-430 stock, with the new piston and same spring I'm now getting about 440-450. The cylinder head seat into my bucking better and I guess thats where the increase in fps comes from.
My only complaint is the trigger itself. It's really sharp, at least this one is, it tore through my gloves after 40 or so rounds. I've since dremeled to to a smoother profile. I would have to say, other than the unit costing 50% of what my gun cost it's a good upgrade and a must have over any stock trigger for a vsr-10. "Good trigger, does what it is supposed to. I'm currently running mine on a m190 spring.

The Angel VSR-10 Cylinder Head and Piston Head:
The inherent design flaw of the Tokyo Marui VSR-10 is its original 45 degree piston head. When a M150 or higher power spring is installed, the piston sear will start to stress the piston and moving the piston forward. As a result, the piston will experience a large amount of friction with the cylinder when you pull and push the bolt. The complete Alpha Pro Trigger System allows provides a Piston featuring a 90 degree aluminum piston with steel end cap and a new concave front end design as well as a stainless cylinder head with concaved rear end design.
Normal Trigger: Angel Custom Alpha Pro Trigger System:
The 90 Degree Cylinder Set is also a great upgrade for existing PDI and PSS10 Zero Trigger Sets performing a higher gas output than the originals.
