Geissele Stressproof Bolt® Assembly with Extractor
Geissele Stressproof Bolt® Assembly with Extractor
The Geissele Stressproof Bolt® is proudly featured in our Reliability Enhanced Bolt Carrier Group. The Forged Stressproof Bolt® is made from Carpenter 158+, directly developed with Carpenter Steel metallurgists to create a material that is cleaner and has less impurities. This makes the Stressproof Bolt® stronger and more fatigue resistant, capable of 5 times the life of a mil-spec bolt.
Each Forged bolt is rigorously inspected, high pressure tested, mag particle inspected and Nanoweapon® coated.

What is Geissele Nanoweapon®?
Geissele Nanoweapon® (also known as Picatinny DSL) is a family of Durable Solid Lubricant coatings which was developed by ARDEC. It is available exclusively from Geissele Automatics. We continued the development of Picatinny DSL so that its level of corrosion, wear and abrasion resistance is currently unmatched among firearm coatings. Nanoweapon® is applied at low temperatures so that the underlying metallurgy of the part is unaffected by the application process. Our coating also has a surface hardness roughly equivalent to synthetic diamond. This makes Geissele Nanoweapon® harder than sand, easily rejecting carbon and making cleaning a breeze, on top of allowing the firearm to operate normally with less lubrication.
