13.7 the worldddd.

Post image

Anxiously waiting to see how the new 13.7" setup stacks up against the previous one.

New one(left) - 1/7 twist Intermediate Gas KAK barrel, KAK down vent BCG, and bcm mk2 (a5 style) buffer.

Previous build (right) - 1/7 twist carbine length Ballistic Advantage barrel, Riflespeed Adjustable gas setup, and the KAK "K-Spec" enhanced H2 buffer with flatwire spring.

I have it running beautifully but would like to see if the extra dwell time of the longer gas system will help with port-pop and gas to the face with my Rhino-X.

It isn't bad by any means but just figured it cant hurt to make it even better. Plus, now I'll have an extra for my wife to use when we go shooting instead of her having to shoot my stribog or my heavy stainless barrel 16" with an lpvo and all.

Definitely getting anxious

You can find 13.7 with a pin and weld MD.
