Geissele Automatics

The Geissele Enhanced 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 our facility in North Wales, PA. Made from proprietary Geissele designs out of Stainless Steel, the Geissele Enhanced LPK ensures a much longer life-span and a much lower chance of rusting or failing in extreme conditions and heavy use. The Geissele Enhanced Lower Parts Kit includes our Maritime Bolt Catch, famous for its aggressive texturing and extended paddles; and our Ambidextrous Posi-Lock safety, which features a satisfying and positive tactile feedback when engaging the safe or fire position. Rounding out the Geissele Enhanced LPK is our Geissele Trigger Guard, which features a wider opening to ease operation while wearing gloves. The Geissele Trigger Guard is machined out of 7075-T6 aluminum and Type 3 hardcoat anodized.
