The Ruger® Mark IV™ 22/45™ is a widely popular rimfire firearm, and for many good reasons. The fully assembled Factory Ruger® Mark IV™ 22/45™ Lower is true to all factory specs and configurations as these frames came from Ruger® and have not been used or modified in anyway.

Made of lightweight polymer, these factory Ruger® lowers boast textured frontstraps and backstraps with checkered 1911-style grip panels for a firm grip, a one-button takedown for easy cleaning and maintenance, and your choice of a black or gold, curved trigger.

All Ruger® Mark IV™ Standard and Mark IV™ 22/45™ pistols share the same, one-button takedown feature. As a result, this factory lower will support virtually any factory or aftermarket Ruger® Mark IV™ Standard or Mark IV™ 22/45™ uppers. This means you could now easily turn your Ruger® Mark IV™ into a Mark IV™ 22/45™. No need to go out and buy all new Mark IV™ 22/45™ magazines either. Turn your Mark IV™ magazines into 22/45™ magazines by swapping out the factory magazine base pads with TANDEMKROSS’s extended magazine bumpers! Try either the “Tomahawk” or “Mark PRO” Magazine Bumpers that both come in packs of two!

Get the most out of your pistol with great TK parts like the “Race Gun” Kit, “Get a Grip” Kit, “Blast Pack” or “Ultimate” Trigger Kit, or any other quality part or accessory for your Ruger® Mark IV™ 22/45™.

Get this fully assembled, genuine Ruger® factory lower today and make your good gun GREAT!

True to order very pleased with delivery and product. Disappointed in price since getting all other necessities to create complete gun cost are way mor than it’s worth.
