What length barrel for CASV 10.5"

[panda86]

Does anyone know what inner barrel length is needed for a 10.5" barrel going into a CASV conversion?

As a general question for inner barrel length requirements, do you just add like 1/2" or something to the outer barrel length? (ie: a standard measurement always goes into the hop up?)

Thanks in advance.

300mm, or 285mm if you want to be on the safer side(300 might stick into the flashhider).

there are no standard way to find the inner barrel length based on the outer barrel length. Alot of guns differs.

300mm is the perfect fir for 11.5" barrels (M733), so if you don't want to see the barrel poking through the flash hider, go with 285 (which is MC51-length).

Cool, thanks guys for the info.

Just to over- confirm, I have a 285mm in my 10incher. Fits flush with the barrel before the flash hider.
