This 18" 5.56 upper is 1/2 MOA with factory ammo. It features an 18" Douglas barrel made by Compass Lake Engineering before they stopped selling to civilians.

The barrel and gas tube are cerakoted Magpul FDE. The barrel has some scratches from installing the gas block, as shown in the pictures.

Parts:
Compass Lake Douglas 18" barrel with CLE chamber
Superlative Arms adjustable gas block
Geissele MK4 rail
Mil spec BCG with headspaced bolt
Mil spec charging handle
Expo upper (tight fit, now wiggle, barrel had to be thermal fit)
FDE dust cover
Rifle length gas tube (fde cerakote)
ASR muzzle brake (can probably swap for something else if preferred)

I’m $1500+ into it.

Asking $1050 or trades involving:

USP 45 Tactical
P226 XFive Legion
Holosun IRIS
P365 FCU
CZ P-09
Quality 300BLK ammo
Open to LMT, KAC, HK, B&T, Langdon, etc.

Can add cash for the right trade. I have FLDL and CWP. Meet in Volusia County.
