Just replaced the handguard on this to the Midwest Ind. 9.5" Combat Rail...Figured I would share...

3-4000 rounds and not a single hiccup using the cheapest, dirtiest Russian ammo, all the way up to fancy Winchester white box

Work ammo is Winchester Ranger, 64gr Bonded Soft Point.

Andro Corp "Crane Spec" 10.3 Upper
ToolCraft Phos. BCG
PRI Ambi CH
Colt FCG
Geissele H3 buffer with braided buffer spring

And well, the rest should be obvious.
