SFL and barrel fit

[Rob @ DNR]

If you own an SFL or extreme E Mag, I just wanted to let you know to look at the module to make sure the barrel you use fits into the groove correctly. I was using an aluminum freak back on a SFL, and had quite a few ball breaks. I removed the module and checked to see if the barrel fit correctly. It didn't. The barrel's OD was greater than the modules ID, causing a gap between the module and barrel. Boomsticks, CP's and every other barrel I can get my hands on fits perfectly. I have yet to try a stainless freak back to see if it fits. If anyone is having problems with balls breakage and is using an aluminum freak, please check your module to barrel fit. Hope this helps anyone that is in the same boat as I was...
Also, if you have a stainless freak back, let me know if it fits correctly. Thanks.

Wasn't AGD or Shocktech offering machining for barrels that don't fit in the breach?

When I was on the phone with Shocktech, I mentioned it to my sales rep. It was the first time he had heard of any fit problems. We concluded that a stainless base may fit correctly, or to remove some of the aluminum on the other base to make a good fit.
