This is the 7.5" Mike Rock barrel w/ Nickle Boron plating (1:7) w/ the proprietary lo pro gas block and gas tube that MSTN sold a while back (very limited numbers)
Professionally built up on a CMT flat top receiver (w/ M4 cuts) and a matching CMT B/C/H.
Daniel Defense 7.0 free float rail.
Has seen about 200 round through it - runs 100% flawlessly w/ a H2 buffer.
All NFA rules apply - this must go on a title 2 lower or a pistol lower.
Price $775 shipped for the complete upper only
Optional items w/ purchase of upper only
Noveske KX-3 w/ Fire breathing pig logo: +$110
Eotech 511 A.65: +$250
If you want it all I will offer it at $1100 shipped for the whole upper as pictured (KX3 + Eotech)
Note, KX-3 is timed such as the Noveske logo is at 12 o’clock, and the pig at 6 o’clock, hence not visible in pictures. Could easily be timed to display logos at 3 and 9 o’clock by using a peel washer. I never cared!
