CMMG Banshee Mk17: A Versatile Gun For A Happy-Go-Lucky Marksman!

Named after the M17 used by the US Army, the feature-filled, super-compact AR pistol, CMMG Banshee Mk17 has entered the market with a bang (pun intended!).

Featuring a 5-inch barrel, this bad boy weighs only 4 pounds 10 ounces and – to the delight of gun enthusiasts with a budget – comes in three different series: the 100, 200, and 300. The number of excellent features increases with the price range, making the 300 series the most premium option (it has ten different Cerakote options!)

After going through this review, you should be able to decide which one you want to get your hands on from Eagle Arms serving Lake Harmony, PA.

What Makes the CMMG Banshee Mk17 a Versatile Gun?

The below-mentioned factors make the CMMG Banshee Mk17 a versatile gun:


The Banshee Mk17’s precision is one of its most outstanding features. The 9 mm round is still a handgun round, and it isn’t built for pinpoint precision. With a red dot and a hasty fighting position, it can shoot a 2-inch group at 50 yards. You can make sub-1-inch groups all day long inside 25 yards.

It’s a PCC with remarkable accuracy. The trigger is a basic Mil-Spec model, but it doesn’t make it less effective. Not all ‘Mil-Spec’ triggers are created equal, and we think this one is rather crisp. The trigger reset is a big chunk that’s hard to overlook. This is top-tier accuracy in terms of PCCs. Since 9 mm isn’t a long-range round, you can’t compare it with specialized 5.56 rifles, but it’s still a fantastic platform round.

Highly Shootable

The delayed roller action considerably decreases recoil, making it a soft and pleasant shooter. The muzzle rise and recoil are minuscule, making the gun a total joy to shoot.

The best thing about the delayed rotary mechanism is that it eliminates the recoil that blowback PCCs are known for. The recoil of many straight blowback PCCs is comparable to that of a 5.56 rifle. The Banshee Mk17 features an incredibly light recoil, similar to the MPX’s light-recoiling gas system.


Both the safety and charging handles are ambidextrous and straightforward to use, so whether you’re right-handed or left-handed, you’re going to be comfortable shooting it. The charging handle, in particular, is large, making the rifle simple to rack.

The magazine release is cleverly-built to fit a pistol magazine into a AR 15 platform. It’s easy to reach with your trigger finger and light enough to be accentuated with only a little pressure.

Final Verdict

This pistol is ideal for use in the home and would be a fantastic weapon for folks who cannot manage a full-sized rifle or shotgun.

All in all, it is undoubtedly a high-end, expensive PCC, but we cannot call it overpriced because it boasts some really attractive features for gun enthusiasts.
