Product description

Easily Convert Your AR-15 Lower to Accept Glock Magazines

The Sylvan Arms AR-15 to 9mm Glock Conversion Block – GCB100 is a drop-in addition that converts your AR-15 lower to a 9mm Lower for use with Glock magazines. This accessory is designed to install in Mil-Spec lowers almost exactly like a standard rifle magazine, without resorting to buying a separate lower receiver exclusively for Glock mags.

This fantastic conversion kit from Sylvan Arms is one of the best accessories on the market today and increases the modularity of your AR-15 pattern rifle.

Takes Your AR Build to the Next Level

The Sylvan Arms AR-15 to 9mm Glock Compatible Conversion Block is designed to fit into the magazine well of your standard AR-15 and reduces all the extra space and allows Glock 17 and 19 pattern magazines to fit. The fit and function of this adaptor are exceptional and genuinely ingenious which makes it one of the best AR-15 accessories on the market today.

It is machined from black oxide steel and 6061-T6 aluminum coated with a black anodized finish for extreme durability and wear resistance. This adapter promotes easy installation and swap-out when needed and takes your AR build a step further to switch that big 5.56mm-sized hole into a 9mm-sized one to fire your favorite 9mm ammo.

  • Easy to install and swap out

Very happy with product works and functions well would recommend this part to anyone
james Verified buyer
I have other conversion blocks but they only accept "Colt" magazines. The Sylvan conversion allowed me to have magazine interchangeability with my SBR and my Glocks and P-80's. ... A pistol / carbine combo and the Sylvan made that happen. So far no issues with the block. It runs as expected...

I loved the piece. Better instructions would have been better. I put it in the lower and it wouldn't go in all the way. Until I realized there was a allen wrench taped to the bottom. When I removed the allen wrench it went right in. Great product overall

Five out of seven Glock mags I have do not fit the mag well. Not pleased with the design. Fits too sloppy in receiver. Will be returning.

james · Some aftermarket magazines (plastic) will bulge when loaded to capacity. Try metal mags only and see if the issue corrects..
