Mk12 Project

[SPO38]

Finally, after almost 11 months and almost $6K, my MK12 Mod 0 build is complete!

A few years ago, I fired a friend's AR which had been modified for (relative) precision, and I knew I wanted something similar. I did a lot of research, and came to the conclusion that the Mk12 Mod 0 is really the pinnacle of precision ARs, and ultimately right for me.

Cool. The red dot looks funny on top of this build. Do you ever use it?

Yes, when he wants to shoot 6" above the target.

OK so how does it shoot?

This. Very nice build but for $6k that thing better shoot 1/4 MOA at 600 yards lol.

Nice. Whats the weight of that tank?

I never weighed it lol

OK so how does it shoot?

I'm obviously not a super marksman, but I've been landing 10/10 hits on an 8 inch plate at 150 yards in about 10 seconds.

Cool. The red dot looks funny on top of this build. Do you ever use it?

Yep. Its zeroed at 20 yards.

This. Very nice build but for $6k that thing better shoot 1/4 MOA at 600 yards lol.

MK12s with 18" Douglas barrels are typically 1/2 MOA, which is not bad. As I said, the lower is pre-ban, so that adds a nice chunk to the price tag, especially considering it had never been fired or even taken out of the plastic.

My Mk12 Mod 1 with a NF optic ran about 3800 total.
