V2 6mm oil bushings
« on: December 06, 2006, 11:27:08 PM »
What would be the best bushings to change out my 6mm oil bushings in my m15a4.  Any help from people that have used different kinds.  I can read ads on the internet, but would like first hand opinions.

From what I know oil-less are the way if you are changing from plastic bushings to metal, but I also have heard that you dont need to change that on a CA m15a4 becuase it already comes with metal bushings.

The bushings you have are fine. If it aint broke, dont fix it. Did you get that spring put in yet?

Yeah Pilz when you said that I figured that different CA guns use different sized busings, I just remembered 6mm because I use an AEG similar to Ocho's.

how does a 7mm bushing gear box affect performance in contrast to the 6mm one?

the 7mm bearings can take a higher level spring yet still maintain a fast ROF.  Using 6mm BEARINGS is suggested for springs less then M100's (330 FPS)  However with 7mm ones I believe you can go up to M130's w/out worrying about htem bursting.  However you can use any spring with BUSHINGS which contain no bearings whatsoever and are basically a peice of metal with a channel in them for oil.

Whoo, I had to read that one a couple times.  This is why I'm afraid to do any upgrades on my gun, I know I'll mess it up in at least one way.
