Over the past few years, you’ve probably seen a massive resurgence of the pistol caliber carbine, most notably the 9mm carbine. Stability is the most significant advantage of the pistol caliber carbine over any sidearm.
You’ve probably also seen some crack shots at the local shooting range who can shoot the wings off a fly at 25 yards with their sidearm. However, for the majority of shooters, handgun accuracy tends to begin dropping off around 15 yards, especially in kinetic situations where the adrenaline is surging and stress levels are through the roof.
The pistol caliber carbine gives you added stability to hit your mid-range targets more accurately and consistently. Maxim Defense recognized this demand in the industry and answered with the MD9 9mm pistol caliber carbine. The Maxim Defense MD9 offers a PDX-like platform chambered in 9mm.

MAXIM DEFENSE MD9
What Sets the Maxim Defense MD9 Apart?
The package weighs in at just over six pounds unloaded, and 20 inches collapsed, adding to the small footprint. The MD9 also boasts an ambidextrous magazine release, Radian charging handle, and selector. It accepts all Glock 9mm pattern magazines, G19 or longer. Rounding out the set-up is a modified Maxim Defense HATEBRAKE muzzle booster and ALG Combat trigger.
An issue seen in previous pistol caliber carbine designs is that the shooter would use the magwell for their support grip, which would cause the magazine to move just enough to cause failure to feed malfunctions. Maxim Defense recognized this issue and mitigated it by extending the length of the magwell, giving the shooter a full support hand grip without interfering with the function of the magazine.
The Modified HATEBRAKE emulates the back pressure of a suppressor. So not only is it directing the blast forward and away from the shooter and those around the shooter, but it regulates the cyclic rate. The advantage of this is whether you’re running the included HATEBRAKE or a 9mm suppressor, the cyclic rate will be consistent and not over-gassed.
Maxim Defense went with a barrel length of 5.8″ to maximize the velocity and hence accuracy of this PCC. The optimal barrel length for the 9mm cartridge is roughly 6″, so with the MD9, you’re getting optimal performance out of the 5.8″ barrel. In addition, the MD9 was tested with 124gr FMJ, which resulted in a muzzle velocity of 1,150 feet per second.
When it comes down to defending your home and keeping your family safe, stack the odds in your favor with the Maxim Defense MD9 pistol caliber carbine.
Faxon Firearms’ recently partnered with RE Tactical to write up what they refer to as the definitive guide to finding the best AR-10 barrel. Buying after-market barrels can be a hassle; maybe this might help. We figured you might be interested in a little less suck in your life.
A Definitive Guide To Finding The Best AR-10 Barrel
The purpose of the AR-10 platform is to get more power and long-range precision out of the AR platform. Who doesn’t want more power and precision?
To capitalize on that power and precision, it makes sense to get the best AR-10 barrel you can find. The right barrel will allow you to maximize the benefits of using the larger 308 round in a semi-automatic AR-10 battle rifle.
Faxon Firearms’ high-quality, affordably priced AR-10 barrels are all manufactured in the United States and ready for reliable and accurate long-range shooting. So whether you’re shooting 308 WIN, 6.5 Creedmoor, or the new 8.6 BLK, Faxon has the right barrel for you.

Faxon AR-10 barrels are also available in Big Gunner, Heavy Fluted, and Pencil profiles. They are made with the finest 4150 Chrome Moly Vanadium or 416R Stainless Steel and rifled for the best possible velocity and accuracy.
Before we get into finding the best AR-10 barrel, let’s answer some of the most common questions about AR-10 barrel selection.
AR-10 Barrel Length Considerations
There is more to consider about the barrel length than its effect on velocity and accuracy. For example, your barrel length will dictate your choice of accessories, such as handguards. Do you want something that just goes past the gas block or something that runs the full length out to the muzzle?
This can be important for aesthetic or practical reasons, such as ensuring that a suppressor or other muzzle device has enough clearance between the end of the muzzle and the handguard. In addition, a longer handguard provides more real estate for accessories like optics, sling mounts, and bipods. Finally, keep in mind that the length of the barrel will play a major part in the rifle’s overall weight, which is something to consider if this is a hunting setup.
What is the optimal barrel length for 308?
Barrels lengths for AR-10 calibers range from 16″ up to 24″. Although 20″ seems to be the sweet spot for the 308, with the right barrel, you can get away with using a 16″ barrel.
How accurate is a 308 16-inch barrel?
A 16″ barrel will do you just fine until you get out to and past 600 yards. Unfortunately, the 308 round will drop significantly past 600 yards, so if you’re going to be engaging targets at distances past 600 yards, you’d be better off with a 20″ barrel.
Is an 18-inch barrel good for an AR-10?
Most 308 WIN loads get full powder burn at roughly 18 inches of barrel length. So for a general-purpose AR-10 build, an 18-inch barrel will do you just fine.
However, even in 18-inch barrels, the profile and gas system length can determine weight. 18-inch barrels can range from a Faxon pencil to a thicker Big Gunner profile and come in both mid and rifle-length types.
What is the most Accurate AR-10 Barrel?
The Faxon Match Series AR-10 barrels take renowned performance and value up a notch.
Manufactured in-house from gun-barrel-quality bar-stock, the Match Series barrels start with 416-R in 5R rifling. 5R is a hybrid rifling with lands opposite grooves and reduced sharp angles that reduce jacket deformation, increasing velocity, and easy cleaning.

The extension is coated in a Nickel Teflon coating that maintains incredible dry lubricity and corrosion resistance. The Nickel Teflon coating also tightens up the fit between the extension and receiver, further improving accuracy. As a result, the Faxon AR-10 Match Series barrels are ready for when duty calls with unrivaled performance.
