Designed, manufactured, and field-tested specifically for law enforcement personnel who require an AR-15/M16 dedicated to 9mm ammo using Colt and modified Uzi-type magazines. Integral leg hooks over the top of the lower receiver to prevent accidental fall-out during actual combat situations where reliability is paramount. Two-piece, aluminum body features extra tight, mating surfaces to minimize the collection of carbon and brass buildup; scalloped hold-actuator allows unburned powder and other debris to pass through for uninterrupted cycling. Hold actuator is wire EDM-machined from high grade, 01 tool steel and functions with the standard 5.56mm bolt hold-open, which is strong, reliable and more readily available than the 9mm version. (Last round hold-open feature functions with Colt magazines only.) Ejector is of standard, Colt configuration for easy replacement by any department armorer. Funneled magazine well ensures smooth entry for rapid mag changes and limits rotational movement caused by variances in magazine taper. Spring-loaded roller maintains constant tension against the lower receiver well to prevent free play. Steel, feed ramp is heat-treated for extra strength and superior wear-resistance; provides consistent round delivery with most bullet types. Armorer installation recommended.

Brownells USA Worked perfectly 14/11/2016

This conversion block worked perfectly. This was my first 9mm AR that I built. Was a little worried about not getting a dedicated lower/upper kit so I did not want to skimp on a cheaper conversion block.



The quality of the block is very high. Feels tough and fit perfectly into the AR lower with no wiggle room. I did have to install it prior to installing the mag release button but that's not any different than any other build I've done.



The Brownell's Colt style magazines fit perfectly again very precise and no wiggle or sloppiness at all. The bolt held back every time the mag was empty. I put around 200 rounds through the combo with zero defects at all. No misfeeds, misfire, or anything. I am very pleased with this item and I know that it'll perform well for anyone.

Definitely recommended

Brownells USA Great Product! 17/10/2016

This is the ultimate 9mm conversion block. Simple installation and flawless performance at the range! Three 32 round mags without a hiccup. Worth the extra bucks!!
