View Full Version : MR1 Upgrades

11-18-2010, 01:48 PM
I'm working on upgrading my MR1. I just replaced the stock trigger assembly with an electric from a Spyder Pilot ACS, and replaced the stock bolt with an ACP Delrin bolt. I haven't chrono tested the gun yet, but it seems a little fast, so I'm also about to get a spring kit. Are there any other internal upgrades I need to make in order to take full advantage of my new automatic capabilities? New striker, valve, anything like that?

I would recommend a regulator and valve, but these are necessary.

Are you running co2 or HPA?

Right now running CO2, but was considering making the switch soon due to winter moving in...

CO2? maybe you can get some new o rings. CO2 broke my internal o rings, and i had to dissasemble the whole thing and replace all of my rings. do that, and a spring should make it good.
