AR15 Carbine and Troy BUIS (Backup Iron Sights)
Brief review of the Troy BUIS (backup iron sights) battle sight system on my AR15 carbine, followed by target shooting at 100 and 200 yards. Shooting segments include PIP; second camera at the target to provide picture-in-picture perspective. The rifle is a combination Bushmaster lower receiver and Rock River Arms upper with a 16" barrel. Typically, I use an EoTech and co-witness with the BUIS, but that product is currently out of commission. I purchased this set of Troy sights from a local gun shop, approx. $220 US retail. Ammo used for target shooting is manufactured by Georgia Arms, .223 Remington, 55 gr FMJ. I have shot a ton of this ammo over the years, mainly with the Bushmaster Varminter, and find it to be reasonably accurate. Targets are 18" x 30", 3/8" thick, 500 Brinell steel, and mfg. by Mike Gibson Targets in Idaho.
