Bayonets
Impact Guns carries bayonets — edged weapons designed to affix to a firearm, usually via the barrel or under-barrel furniture. Whether you’re outfitting an AR-15 or looking for a fixed-blade option, the right bayonet depends on your rifle’s mounting hardware and how you plan to use it.

Auto vs. Fixed-Blade Bayonets
An auto bayonet deploys its blade with a button or lever for faster one-handed use, while a fixed-blade bayonet has no moving parts and is generally simpler and more durable. Auto bayonets add convenience; fixed-blade designs add reliability with fewer parts to fail.
Bayonet Mounting: Lugs, Rails, and Compatibility
Most modern bayonets attach via a bayonet lug near the muzzle or a dedicated mounting stud. Not every rifle has one from the factory — confirm your barrel, handguard, or muzzle device actually supports a bayonet mount before buying, since retrofitting a lug can require a barrel or handguard change.
Are Bayonets Legal to Own?
In nearly every U.S. state, bayonets are legal to own as edged weapons. A small number of states restrict specific blade types, lengths, or carry methods, so check your local and state law before purchasing, especially if you plan to carry one outside the home.
