Beavertail Expansion for EVO Glock 17/19/45 Gen 6 Chassis Systems

If you picked up one of the new Gen 6 Glock 17,19 or 45 and want to run it in your MCK EVO, this is the piece you need.

The MCK EVO Conversion Kit already works great with Glock Generations 3 through 5. This MCK EVO Glock Gen 6 Beavertail Expansion brings the Glock 17 Gen 6, Glock 19 Gen 6, and Glock 45 Gen 6 into the same chassis with a solid, factory-tight fit.

Just swap the beavertail on your existing EVO and your Gen 6 pistol drops right in. No modifications, no gunsmithing. In seconds you’ve turned your handgun into a stable, carbine-style PDW platform.

Key Features

• Built for Gen 6 Frames: Precisely matches the updated frame and beavertail of the Generation 6 Glock 17, Glock 19, and Glock 45.
• Expand Your Existing Kit: Upgrades any current MCK EVO (originally made for Gens 3–5) to accept the newest Gen 6 models without buying a whole new chassis.
• Solid Lockup: Contours perfectly inside the MCK EVO chassis so your Gen 6 stays locked in during rapid fire and hard use.
• True Drop In Install: Swaps onto your existing EVO in seconds. No gunsmithing, no permanent changes, and no special tools required.
• Duty-Grade Construction: Made from the same high-impact, temperature-resistant polymer as the rest of the EVO chassis for long-term durability.

Compatibility Note: Designed specifically for Generation 6 Glock models 17, 19, and 45. Requires the base MCK EVO chassis system (sold separately).

Assembles the same as all previous EVO beavertails. Uses 2 mm Allen Wrench (included in polybag)
