Easy Maintenance: The ejector is of standard Colt configuration for straightforward replacement by any department armorer.
Quick Mag Changes: The funneled magazine well facilitates smooth entry for rapid magazine changes while limiting rotational movement.
Constant Tension: A spring-loaded roller maintains constant tension against the lower receiver well to prevent free play.
Enhanced Strength: The steel feed ramp is heat-treated for superior wear resistance and consistent round delivery with most bullet types.

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.

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!!

Worth it 27/08/2012

Bought for a 9mm build on a generic CMC produced 5.56 lower, using a CMMG dedicated upper and CMMG buffer and Metalform Mags. Skeptical at purchase--but fit exceptionally well, and flawless in operation/function. The installation is benign--all you have to do is partially remove the bolt catch pin; temporarily remove the bolt catch long enough to slide the Hahn insert into the mag well from the top--then reverse the process. I think I spent 3 minutes on the whole deal. Bottom line: the quality and craftsmanship is recognized best when viewing and inspecting the device after installation. Precisely machined and finished. (Hence the brand name) And, Mag well has great machined tapers for mag fit. If you did not CLOSELY inspect, you might think this was a dedicated 9mm lower.
I like mine--zero malfunctions and over 600 rds.

For the Serious 9mm AR-15 Shooter 04/06/2011

Had not been impressed with performance of bottom loading and plastic blocks used by some of my shooting friends and was somewhat leary of them. This dedicated top loading conversion block is a semi permanent installation in your lower and not a quick change. The block can be removed but not as quickly as the bottom loaded units. Required very minor filing of the inside of my lower's mag well and removal and re-installation of the bolt catch. But, this is what makes this block as reliable as a dedicated 9mm lower receiver and it cannot fall out of the receiver! Functions flawlessly with the Metalform 20 round magazines and holds the bolt open after every last shot. Buy this one first and save money, you won't be disappointed. I am one happy 9mm Carbine shooter.
