Angryrhyno Posted July 5, 2010 Share Posted July 5, 2010 Hi everybody, I'm putting an m4 long barrel on my old tm mp5 to give it a little more range and acuracy. M4 barrel fits, just need to find a nice "silencer" to cover the excess length sticking out the muzzle. Does anyone know if i need to uprate the piston/spring etc when i do this to make up for the longer barrel length? Let me know please. Cheers.

My mate has lots of fields we have built bunkers and stuff in. Played at the Jersey site but wasn't impressed with the way its run. Will be playing in the Guernsey site soon hopefully which is why i'm adapting the MP5. Link to comment Share on other sites More sharing options...
