M4A1 Block 2 FSP Upper Receiver, Military Special
This is top shelf. You might not need top shelf, but if you want it, this is it. Charlies's Custom M4A1 with the FSP / front sight base and all the bells and whistles. Period correct. Dope !
We held nothing back with this upper receiver group. Colt "C" marked upper receiver, Colt SOCOM 14.5" barrel with Surefire 4-prong flash hider, Daniel Defense M4A1 FSP rail in FDE, Colt BCG, and Tango Down Scar Panels and Vertical Forward Grip in FDE. The Block 2 is a great rifle, and some like the flattop rail, but there is just something that says classic about the Front Sight Base rig.
Ready to pick your optic and rear back-up sight of your choice. Charlie's likes the Matech 600 meter for iron sights, and your choice of a tan EOTech or Aimpoint M68 sight with a Wilcox mount, or maybe an Elcan with RMR. You can even put a Trijicon ACOG on if you wish. Just be sure to match this up with a Colt lower, laser-cut ID sticker and B5 SOPMOD Coyote stock and a sling for your rig.
