C308 question

[MSOGDAWG]

So I have a Century C308, it has a 18" barrel. Question is - would I be changing very much of the guns operating cycle by chopping 2 inches from the barrel down to 16" ? Would I need to change locking pieces?

Here is a locking piece chart I found...

HK Locking Pieces

Not very helpful I'm afraid

Manofdusk or Ghilliebear would know for sure, what say you guys?

I think that a #18 (45 degree) LP may be in order--- @Ghilliebear would know.

Thanks for the info gents. Curious to see what @Ghilliebear and @Manofdusk have to advise.

I've built some G3's and used 16" barrels on them. I didn't have to change the locking piece and they worked fine. Jeff is the expert though so I'd wait to see what his opinion is before you chop the barrel down.

I would suggest a standard G3 locking piece.. You would not be changing the gas system very much. If you had any type of ejection issues then I would go with a number 18. Or possibly decrease your bolt gap.

You adjust bolt gap by changing roller diameters, correct?

Correct.
