The Agency Arms magwell is ideal for those looking to up their Glock game. The magazine well provides an extra "bump" to rattle the magazines as they sit in the pan. The smooth interior also allows the installation of an Agency Arms sound suppressor or can be used in conjunction with an external sound device such as an ECR suppressor. The smaller overall footprint of this magwell also allows it to be installed in conjunction with any Agency Arms sound device (e.g. ECR, ECU, etc) without being oversized. The product is machined from stainless steel and is TIG or machined from hardened tool steel.
