Frequently Asked Questions

What are the advantages of an AR 9mm barrel?

A 9mm barrel bridges the gap between a rifle and a handgun and is a great choice for AR rifles, pistols, or SBRs. They are compact, easily maneuverable, accurate, and comfortable. If you want the AR experience without excessive concussion, recoil, or ammo costs, a 9mm barrel is a perfect fit.

Which barrel length is right for you?

The right barrel length for you depends on your shooting needs and preferences. Generally speaking, shorter barrels are best for home defense and maneuvering in tight spaces.

Also, consider that when you add 1 inch of length to a shorter barrel, its foot-per-second velocity can increase by up to 200 feet.

Is 9mm more powerful than .223?

Ballistically speaking, 9mm does not eclipse .223 in terms of foot-pounds of force or velocity. While .223 can move at over 3,200 feet per second (fps) and offer at least 1,300 foot-pounds (ft-lb) of force, the 9mm only moves at about 1,200 fps and offers around 400 ft-lbs of force.

How many rounds will a 9mm AR barrel last?

You should follow your manufacturer’s recommendations for maintaining and replacing your barrel; your instruction manual should state the approximate number of rounds you can expect to fire through your barrel throughout its life.

Can you purchase a complete 9mm upper receiver?

Yes! If you’re looking to save time at the bench or simplify the parts sourcing process, consider purchasing a complete 9mm upper receiver with the barrel already installed. Attaching a complete upper to a lower receiver and stock is a simple installation option for quick assembly time.
