Just got two lowers from PSA. Im gonna start a a mk18 clone first. Any tips on the build for do's and dont's. I'm looking at going with a 11.5 in barrel instead of the 10.5 I heard of problems with the shorter barrel.

I know the reason is because of the problems over read about with a shorter barrel

I have a 10.5" barreled pistol and it runs 100%. the 11.5 will give you better ballistics over the shorter barrel.

I have an old factory Sabre Def 10.5 SBR with upwards of 40k on it. Runs like a sewing machine

Good to know I will post pics as the build comes together, I think the 10.5 will look better due to wanting a rail that ends just short of the end of the barrel.

10.3 is the correct length for mk18.

Is it a clone if it's not really a clone?

I did a MK18-ish build using a 10.3" DD barrel with a H buffer and a SpringCo blue spring and it ran great.  I then switched to the Ultra Compact stock set up with proprietary H and Spring and it runs just as good.  IMO for a CQB rifle, 10.3" is where it's at!!

BCM doesn't make a 10.3 (or 10.5) barrel but they do sell the Daniel Defense 10.3 bbl. BCM doesn't like going any shorter than 11.5" and here's why.
