This lot consists of one UTM RBT Target Shooting Kit designed as a specialized conversion system for AR-15 style rifles chambered in .223 UTM CTA. The kit features a bolt carrier group conversion unit with a black finish, a prominent blue side insert, and a yellow polymer rear component. Technical markings on the carrier are transcribed verbatim as S/N 000172388 U, followed by a crown logo and M16/M4 UTM AMMO ONLY. Accompanying the conversion unit is one Magpul PMAG 10 AR/M4 GEN M3 ten-round polymer magazine, which is clearly marked 5.56 x 45 and MADE IN USA. The collection includes a lot of fifty individual .223 UTM Target Ammunition cartridges housed in a blue plastic tray; each cartridge is composed of a silver-toned casing and a blue polymer projectile tip. Also included is a dedicated cleaning and maintenance tool with a threaded brass end, the original Owner?s Manual For CTA Conversion AR-15 Style Rifle, and the factory product box. This kit is intended for short-range target practice and training using non-lethal munitions.

The bolt carrier group conversion unit is in very good condition, showing only minor surface dust and light handling wear to the black finish. The action appears to function correctly, and the bolt face is clean. The Magpul PMAG 10 magazine is in excellent condition with no visible structural damage. The lot of fifty cartridges appears factory-new and live, with no signs of corrosion or casing deformation. The original cardboard box shows moderate shelf wear, including some fraying at the edges and a few small punctures, while the manual and cleaning tool remain in good, serviceable condition.
