Frequently Asked Questions

The Geissele Super Duty AR-15 rifle is chambered in the 5.56x45mm NATO cartridge. This is by far the most popular cartridge for AR-15 rifles, as it offers low recoil, tons of versatility and wide accessibility to available ammo types ranging from inexpensive plinking ammo, match grade competition ammo, and soft point hunting ammo.

The forward assist on an AR-15 is a device that allows the shooter to close the bolt quickly if or when a cartridge does not sit correctly in the chamber. If a mis-seated round occurs without a forward assist, the bolt is held open, and the firearm is rendered inoperable until fixed. The forward assist feature is a short-term fix for the problem.

A semi-automatic weapon can fire one round for each pull of the trigger, while a fully automatic weapon can fire multiple rounds with each trigger pull. Fully automatic firearms are also regulated through the National Firearms Act (NFA).

Geissele Nanoweapon is a family of Durable Solid Lubricant coatings which was developed by ARDEC. It is available exclusively from Geissele Automatics. Its level of corrosion, wear and abrasion resistance is currently unmatched among firearm coatings. Nanoweapon coating has a surface hardness roughly equivalent to synthetic diamond. This makes it harder than sand, easily rejecting carbon and making cleaning a breeze, on top of allowing the firearm to operate normally with less lubrication.
