IFC AR-15 410 Upper w/5rd Mag & Flip Up Rear Sight

The gas-operated upper is fitted with an 18.5" smooth bore barrel, dust cover, forward assist, charging handle, bolt carrier assembly, and a flash hider. It also includes a set of "Magpul-ish" flip up sights. It comes with one single stack 10 round polymer magazine which is about the same size as a 30rd 5.56 mag. In addition 5 round (similar size to 20rd 5.56mm magazine) and 15 round (similar in size to 40rd 5.56mm mag) magazines are available for under $20.
While the manufacturer claims a 4lb weight, our example came in at just over 4lb, 12oz.

Due to inconsistencies in the length of .410 shells, the following parameters are recommended:

• Use .410 shells with a minimum of 1200 FPS
• Use shells short enough to be easily loaded into the magazine
• Do not try to put more shells in the magazine than it's capacity
• For best results use shells 2.25" in length

Recommended ammunition that has been tested:

• Remington Game Loads 2.5"
• Remington Express Long Range 2.5"
• Remington Premiere STS 2.5"
• Hornady Critical Defense Ammunition 2.5"
• Monarch 2.5" ( Available from Academy )
