YAY for me! Here is my new 9mm build.

[MarineSniper8541]

Colt lower
RRA 9mm upper
RRA bolt (ramped)
RRA mag block with bolt hold-open
RRA 9mm buffer
Brownells chrome silicon buffer spring
KNS Gen2 Mod2 pins in FDE
DPMS type large pin hammer
PRI 9mm Gas Buster
Troy front and rear BUIS
Aimpoint CompML2
A.R.M.S. M68 throw lever mount with cantilever spacer
Tango Down stubby QD vertical grip
Magpul CTR commercial and MIAD
Yankee Hill light weight rail
TROS 5" 9mm 3-lug barrel
Yankee Hill Wraith XL 3-lug

Refinishing on the lower, upper, rail and receiver extension done by LRM Tech with Norrell Finish moly resin in flat dark earth.

This thing holds a 3 inch group at 100 yards with 115 grain FMJ with only about 4 inches of drop from the muzzle.
At 25 yards and in, you can blow the X ring out with ease. There is almost zero bounce and the recoil is VERY manageable.

Yes,

They are Coyote Tan Promags. They work very well and are not expensive.
