I've been reading a book ("Lone Survivor") by Marcus Luttrell about the battle battle in Afghanistan that took the lives of his buddies. It's a great read (although very sad) and it's not geared about the weapon systems in detail but he mentions his "MK 12" rifle in a number of places. I've done some basic googling on it and it appears to be a hot-rodded AR. The question I haven't been able to answer is what type of gas system it has on it. Does anyone have any info on that? (is it a piston system or just an AR with a non-standard barrel length and free float handguard?)


Anyway that's my question. If anyone's interested in our Seal teams the book is a good read. I know that even in my prime I couldn't have made the first day of their training I don't think. :)

Have a good one,
Dave

The 'interweb' is your friend (well sometimes).

It's a standard direct impingment AR gas system.

Yup, been there read that . ..I don't see any mention of the type of gas system on that page. Am I missing it somewhere?

It is a rifle length direct impingement gas system with an 18" barrel.

It looks very similar to several civvie offerings out there...I know Sabre is making 18-in barrels....

Like Mr. Roberts said, the SPR (what we Army folks call the Mk 12) is a conventional AR in terms of its operating system. Impressive range and accuracy with 77 grain Mk 262 ammo running through it.
