All on A3 16 inch with carbine handguards..
ARMS #40 BUIS, ARMS #38 EX Sleeve, ARMS 22M68
ARMS #40 BUIS, ARMS 22M68, Cantilever spacer
ARMS #40 BUIS, ARMS 22M68, KAC RAS II FF
What is the placement of the Aimpoint with repsect to each of these configurations
(height and forward)?
Pro's con's of either?
Does the RAS II FF provide more or less effective FF than the 1 piece FF M4 RAS?
Thank you sir..... TR
