Brigade BM9 problems

1. Feeding Problems

Feeding issues with the Brigade BM-9 are problems with chambering and cycling of ammunition during the firing process. If your gun wont feed, then you’ll obviously have issues firing consecutive rounds.

Several factors can contribute to feeding problems including using the wrong ammo, damaged magazines, or a broken extractor. The most common culprit is the use of improperly sized ammo. The BM-9 is chambered in 9mm and random sized ammo should not be used.

To fix feeding issues with a BM-9 AR pistol, you should first make sure you are using the correct ammo that meets Brigade’s specs. It is also a good practice to regularly inspect and clean your magazines to make sure they are in good shape. If your new BM-9 is having issues, it is likely from manufacturing defects & you should contact Brigade Manufacturing to get it sorted.

2. Gun Jamming Issues

A gun jam is when your gun fails to cycle properly & prevents the discharge of the next round. In other words, the gun won’t fire.

There are several factors that can cause jamming problems including use of the wrong ammo, built-up debris, or excessively worn magazines. In my experience, the most common culprit of hamming issues is a built-up of dirt & debris in the pistol’s chamber, barrel, or internal parts.

To fix gun jamming issues with your Brigade BM-9 AR pistol you should clean your firearm properly. Clear out all excessive debris build up & lubricate the barrel and surrounding parts. Regular maintenance and attention to detail can fix most jamming issues. Find a qualified gunsmith if you need more help or specific parts replaced.

3. Barrel Problems

Barrel issues with the Brigade BM-9 are malfunctions related to the pistol’s barrel (barrel thread or barrel nut). These types of issues can significantly affect your guns accuracy, reliability, and overall performance.

An excessive fouling and carbon buildup inside the barrel is the most frequent cause of these type issues. You’ll know you have a worn-out barrel if you see issues like pitting, erosion, or excessive wear of the rifling.

Focus on regular maintenance and care to address barrel issues with a Brigade BM-9 AR pistol. Although it can be annoying for some people, cleaning the barrel thoroughly after each use helps prevent dirt and carbon buildup. Using the correct size and high-quality ammunition to prevent undue stress on the barrel and further extend its lifespan.

4. Damaged Bolt Catch

A bolt catch is the mechanism responsible for locking the bolt carrier group (BCG) to the rear position after the last round is fired. When your BCG is locked back it’s a clear indicator that you have an empty magazine. When your bolt catch is damaged it can be difficult to insert a new magazine during reloading.

Several factors can lead to damaged bolt catch issues with a BM-9 AR pistol including wear and tear over time, excessive force on the bolt catch, or poor-quality magazines. Forcefully slamming the BCG to the home position is the most common cause of broken bolt catches.

To fix damaged bolt catch you’ll likely have to replace it altogether. Unless you have done this before, consider finding a local gunsmith to get it sorted. Shooters should also make it a habit to regularly inspect for signs of wear, breakage, or deformation in the bolt catch & other components.

Can Accessories Be Mounted On The BM9?

Yes, additional accessories can be mounted on the Brigade BM9 AR pistol depending on the shooters intended use case. Shooters can use the Picatinny or M-LOK rail system on the handguard just about any accessor they can think of.

Here are 3 of the most common types of accessories that are used with the BM9.

  1. Optics. Red dot sights, holographic sights, and scopes (not common).
  2. Lights. Tactical lights can be attached for low-light shooting.
  3. Lasers. Great for close-quarters & tactical situations.

BM9 Accessories

These accessories can greatly enhance the performance and adaptability of the Brigade BM9 AR pistol. However, some shooters have issues installing or deciding which accessory is best for their needs.

Is It Hard To Mount Gun Lights On The BM9?

It is easy to mount a tactical gun light on your BM-9 for experienced shooters. Certain types of tactical lights can be more challenging than others to install successfully. We recommend that shooters use a dedicated mounting system like the Trex Arms Lightbar, to mount their tactical light like the Streamlight TLR7A or Streamlight TLR7.

Is It Challenging To Attach Red Dot Sights On The Brigade BM9?

No, attaching red dot sights on your Brigade BM9 is a more straightforward process. The BM-9’s receiver rail provides a stable platform f& makes it very simple to mount a new pistol red dot to your gun. Two excellent options for red dot sights compatible with the BM9 are the Vortex Venom and Vortex Viper.

Are Magnified Scopes Too Big To Be Mounted On The BM9?

Magnified scopes can be mounted to your Brigade BM9. Just like we red dot sight, the rail makes the mounting process easy for new and experienced gun owners.

However, mounting a magnified scope on the BM9 is probably not be the most practical choice for most people. The BM9 is designed as a compact and lightweight AR-style pistol, and throwing a large scope on top will add significantly to the weight & balance.
