It started as a Sig 556 Pistol! Easier to mod due to the barrel length.

I looked hard into them and the 552/3 lower was not cheap by any means, but it's the only real way to go from what I saw. Good on you for making it happen. They're lovely guns.
holy cow
I have a few dozen
The MK17 was meant for 13 inch CQB barrels. Studies were done on the SCAR and there was no noticeable difference between the 16inch Carbine and 13inch CQB. with the twist rate 7.62 stabilizes and is still sub MOA. Not to mention that there is specific ammo for this specific weapon, MK319 Mod 0 SOST ammo. I have some boxes somewhere Ill look around.
You will not be unimpressed. 0 recoil. suppresses amazingly well. Hearing safe even out of an SBR
The MK319 SOST is the 130gr Barnes, right? I seem to recall that the bullet isn't even commercially available, but only similar rounds are.

Let me pull some out. They are boxed by Federal. Not sure of the actual bullet.
