Geissele Ultra Duty Lower Parts Kit, No Grip LPK AR15 AR-15 also available in .308 AR10 LPK Option

The Geissele Ultra Duty Lower Parts Kit is made for the most demanding operators and includes all the internal parts necessary to complete or rebuild your lower receiver. This top-tier LPK features proprietary Geissele designs, machined with great care at our facility located in North Wales, PA. Key components are made from Stainless Steel, which offers a much longer life-span and a much lower chance of rusting or failing in extreme conditions or under heavy use. The Geissele Ultra Duty LPK includes our Maritime Bolt Catch, famous for its aggressive texturing and extended paddles, and our Ambidextrous Super Configurable Safety, which features the ability to easily and securely swap and exchange the safety levers plus provides the end user a satisfying and positive tactile feedback when the safe or fire position is engaged. The takedown pins and mag release button feature the same tank treading as the Maritime Bolt Catch, giving your rifle a tasteful and cohesive look. Included in the Ultra Duty LPK is Geissele’s Ultra Precision Trigger Guard, 5-axis machined out of a solid block of billet 7075 -T6 aluminum and Type-3 hardcoat anodize to ensure that your build stands apart from any other.

REVIEW

***** Quality - jim

Not all parts kits are created equal. This ultra duty kit is a perfect example of this. You can tell this is a quality parts kit. I compared this kit to a run of the mill kit. The springs are spun even and straight. The pins are machined nicer. The safety and bolt latch and mag release are just nicer than any others. Well worth a couple extra bucks. If you building a keeper then this kit is a no-brainer.
