[SHOT Show 2020] Marrying 2 Platforms! NEW ATI Milsport AR .410 Gauge Shotgun

When it comes to shotguns the stalwart cartridge that everyone uses is undoubtedly the 12 Gauge, but there is another round that has been creeping up the rear in popularity in recent years and that is the .410 Gauge. With mild recoil, light noise, and more unique firearms being created as of late to shoot .410 Gauge , it has found a new resurgence of use by many shooters. One unique firearm to come from SHOT Show 2020 chambered in .410 Gauge is the American Tactical (ATI) Milsport AR .410 Gauge Shotgun.

This shotgun melds some of the best properties of the .410 Gauge shell into the common and versatile platform that is the modern sporting rifle or AR-15. You have the ability to shoot 2 1/2″ .410 Gauge shells out of a rifle that can have its upper switched out and be blasting 5.56mm NATO moments later; talk about utility! The specifications for the ATI Milsport AR .410 Gauge Shotgun can be read below as presented by American Tactical:

USA Forged Aluminum Upper and Lower Receiver
Proprietary and Patented Magazines that fit into a Mil-Spec AR15 Lower Receiver (5 and 15 Round)
18.5” Barrel with Dull Hard Chrome Finish
13″ M-LOK Free-Float Handguard
Gas-Operated, Short-Stroke Adjustable Piston System

Mil-Spec Fire Control Group
6-Position Rogers Super Stoc
Metal Front and Rear Flip-Up Sights
One (1) 5-Round Magazine
Includes 1 Proprietary External Choke Tube

The MSRP for this .410 Gauge hybrid is currently set at $719.95, and it is manufactured in South Carolina, USA by ATI. So, this is truly an American product! It comes with just the one 5-round magazine and one proprietary external choke tube, but additional chokes and magazines can be purchased separately on ATI’s website. An even more in-depth explanation of this AR-shotgun can be read below as presented by American Tactical:

“American Tactical is proud to release the Milsport 410 semi-auto shotgun!

Built with our patented 410 gauge modular upper receiver, this 410 is the perfect shotgun for small game, large game, home protection and target shooting. Chambered for 2 1/2″ .410 ga shells, this 410 is a must have multi-purpose shotgun.

Featuring an 18.5″ barrel with a custom 13″ keymod rail, the Milsport 410 runs on a gas operated, short stroke balanced piston system.

Each Milsport 410 comes with one 5 round American Tactical polymer magazine. Additional 5 round magazines are available for seperate purchase. The Milsport 410 will only operate with the patent pending American Tactical polymer 410 magazine.

Every Milsport 410 is built on our Milsport lower receiver and can be converted to 5.56 or 300blk just by changing the upper receiver! Every Milsport 410 upper receiver is built to regular AR spec and can be installed on most mil-spec lower receivers!“

As if the ability to fire 2 1/2″ .410 Gauge shells from an AR-15 platform is not cool enough, you still have the ability intact to remove the upper assembly and shoot common rifle cartridges like 5.56mm NATO and 300 BLK through it as well!
