New 9mm Carbine: the FX-9

Share:

The popularity of the 9mm carbine has really taken off in the past few years. Where pistol caliber carbines were once a bit of an oddity, the 9mm in an AR platform has become quite popular. One of the newest rifles pairing the AR with 9mm is the FX-9.

Developed by Freedom Ordnance, the FX-9 has many of the features that a 9mm rifle buyer would be interested in. Let’s go over a few of them now.

With a few exceptions, there are two basic pistol caliber AR style carbines on the market: those that feed from Colt pattern magazines and those that feed from Glock pattern magazines. The Colt guns have been around a lot longer – back to the 1980s. While newer, Glock feeders have become extremely popular as they allow a shooter to use the same mags in both his or her pistol and rifle.

The FX-9 uses Glock pattern magazines, and it ships with one 33-round magazine. Although the company does not state who makes the magazine, from the photos it would appear the magazine is provided by SGM Tactical. If you are not familiar, SGM Tactical makes a number of extended magazines for the Glock line of pistols. Generally, they get good reviews and come in at a much lower price point than the OEM Glock magazines.

Good news about this gun: it has a last round bolt hold open. That’s not always the case with 9mm AR rifles.

Freedom Ordnance uses a threaded 16” barrel with a birdcage style muzzle device. The thread pattern is ½”-28 which is fairly common for suppressors and other devices. Around the barrel is a 13” aluminum handguard uses M-LOK attachment points for the addition of accessories. A M-LOK compatible 3” length of Picatinny rail comes with the gun.

Many AR aftermarket parts will work with the FX-9. This includes things like drop in triggers. Even so, the company was able to reduce the size of the upper and lower to help keep weight down. Blow back guns can be a little heavier than gas operated guns. However, the FX-9 has a weight of only 6.1 pounds.

If you find yourself enamored with the FX-9, you will find that they are affordable. Where many 9mm AR carbines are selling in excess of $1,000, this gun stands out with a suggested retail price of only $799. Even better, I’ve seen these guns offered as low as $599 online. Assuming these guns run well, that sounds like a pretty good bargain to me.

    I’ve had mine for roughly 2 years and still love it. It remains my home defense carbine. I use three different brands of mags and they all work very well. I do not use any SGM mags, personal choice. I’ve put a couple thousand rounds through it with no malfunctions attributed to the rifle. I had some dirty mags and as soon as I cleaned them up, they ran fine. One thing I did that made it even sweeter is I changed out two of the buffer steel weights for tungsten weights. It is very soft shooting. I also added a Kaw Valley linear comp and that reduced the noise level noticeably. I load 147 grain copper plated rounds at 1050 fps and it loves the heavier bullet.
