M4 Upgrade

[boomstick]

I need to get an M4 upgraded to 400fps soon, and was wandering if you guys up at txpb can also do more than spring and metal bushings, like fuse removal, if so reply on what you can do and how much it costs. Thanks

Sure, other upgrades can be done. Contact Obsidian to see if he has the bandwidth.

I don't recommend removing the fuse though. Unless you want the increased chance of frying your motor, it won't do you much good to take it out. It is there as a safety measure for your motor. Additionally, it is a good barometer to tell if you have any problems that are not easily noticeable.

Thanks man, I'll contact Obsidian.
