View Full Version : DSA ZM4 20" fluted?

I have the DSA 16" m4 upper and am impressed with the quality even though it was not very much money. I was wondering if anyone can attest to this 20" fluted model with a 1:7 twist? Sounds like everything you'd want out of an upper and I'm not intrigued by bells and whistles. That being said, anyone got a review for me? Been searching the web for a bit now and no one has a review on this specific model. Thanks.

I have a 16-in version, the fluting is very shallow. I think I have 350-ish in the upper w/o BCG.

Got the 16" too. Like it a lot!
