Product Description

The Geissele Super Duty Lower Parts Kit includes all the internal parts necessary to complete or rebuild your lower receiver. All key components on this kit are manufactured in-house at Geissele’s facility in North Wales, PA. Made from proprietary Geissele designs out of Stainless Steel, the Geissele Super Duty LPK ensures a much longer life span and a much lower chance of rusting or failing in extreme conditions and heavy use. The Geissele Super Duty Lower Parts Kit includes Geissele’s Maritime Bolt Catch, famous for its aggressive texturing and extended paddles; and Geissele’s Ambidextrous Posi-Lock safety, which features satisfying and positive tactile feedback when engaging the safe or fire position. Rounding out the Geissele Super Duty LPK is our Super Duty Trigger Guard, which features a wider opening to ease operation while wearing gloves. The Super Duty Trigger Guard is machined out of 7075-T6 aluminum and Type 3 hard-coat anodized.

Great LPK for a SOPMOD AR build.

This is a high quality kit for SOPMOD builds. It features many enhanced parts that are of high quality and fit well. I am a repeat buyer of this kit with purchasing three of them so far and will continue to buy more for high end future builds. Mil-Spec Retail is a good place to shop because of their accurate running inventory , good prices and fast free shipping. I am happy with both the product and dealing with Mil-Spec Retail who sold it to me.
