This video highlights two significant drawbacks of the BC Nine firearm: its failure to reliably lock back on an empty magazine, even with multiple Glock magazines, and its non-standard 1/2 x 36 thread pitch. The speaker, demonstrating experienced firearm operation, notes the inconvenience of sourcing compatible muzzle devices for suppressors due to the unusual thread pitch. These issues impact the firearm's practical usability for everyday carry and suppressor integration.

This review compares the Zastava M85 and M92 pistols to the popular Romanian Draco, highlighting Zastava's superior fit and finish, factory-installed optics rail, and better suppressor compatibility due to improved thread concentricity. While the Draco is more affordable and offers broader furniture options, the Zastava models are presented as a more refined choice for those prioritizing these specific features. The comparison also touches on barrel length differences and their minimal impact on velocity for 7.62x39mm ammunition.

This video demonstrates how a single 9mm suppressor can be adapted for a variety of firearms, including pistols, pistol caliber carbines, and even some rifles. The key to this versatility lies in using the correct accessory: a booster for tilting barrel firearms and a solid mount for fixed barrel firearms. The presenter, Deuce, emphasizes the importance of matching thread pitches and using appropriate ammunition, particularly subsonic rounds for rifles, to ensure safe and effective suppression across different platforms.

This guide details the process of timing muzzle devices using the Precision Armament Acuasher shim kit. It emphasizes using the correct shim thickness, understanding thread pitch, and applying proper torque for secure installation. The method is applicable to various rifles, including AR-15s, and is suitable for flash hiders and suppressor mounts.

This video from CMMG explains HUB compatibility for their Zeroed line of suppressors. It details how to remove the included direct thread adapters and install aftermarket HUB-compatible mounts, such as quick disconnect systems. The primary thread pitch for CMMG's Zeroed suppressors is 1.375x24 (1 3/8" x 24 TPI), a common standard in the suppressor industry.

This guide details the process of installing a muzzle brake on an AR-15, emphasizing the critical step of verifying thread pitch compatibility. A professional gunsmith highlights a common mistake where a 5/8" thread pitch brake was presented for a standard 5.56 AR-15, which typically requires a 1/2" x 28 pitch. Proper identification and matching of thread specifications are crucial for safe and effective installation.

This review of the Grand Power Stribog SP45A3 in 45 ACP highlights its PDW/PCC suitability for home defense. The firearm features a roller-delayed blowback system, ambidextrous controls, and a monolithic rail. While generally reliable and accurate, the non-standard 5/8x24 thread pitch on the barrel is noted as a significant drawback for suppressor compatibility, requiring an adapter.

This video introduces the Banish 9K, a new 3D-printed titanium 9mm suppressor from Banish Suppressors. It highlights the suppressor's exceptionally light weight (2.7 oz) and compact size (4.1 inches), making it suitable for both PCCs and semi-automatic handguns without requiring a booster. The Banish 9K is rated to bring 9mm down to 132 dB and is limited full-auto rated for subsonic 300 Blackout. It is available in 1/2x28 and 13.5x1 metric thread pitches.

This video provides an initial unboxing and overview of the Zastava Arms ZPAP M85, a 5.56x45mm AK-pattern rifle. The presenter highlights its features, including the last round bolt hold open, wooden furniture, and a unique 26x1.5 left-hand thread pitch. He also discusses the benefits of 5.56 AKs due to ammunition costs and praises Zastava Arms' quality.

This review of the Kriss Vector SDP Enhanced in 45 ACP highlights its unique Super V recoil system, which effectively mitigates muzzle flip and recoil, making it fun and fast to shoot. However, the video points out significant drawbacks including limited customization options on Gen 2 models, a proprietary 1-10 RH barrel thread pitch causing suppressor compatibility issues, and most critically, recurring reliability problems, with jams occurring approximately every 100-200 rounds, primarily attributed to Glock magazine feeding. While a cool range toy, these issues question its suitability for serious self-defense roles.

This guide details four primary suppressor mounting systems: direct thread, proprietary muzzle brakes, Hub industry standard, and Trilog. It explains the installation process for each, highlighting thread pitches, compatibility, and potential impact on firearm zero. The video also touches on pistol suppressor mounting and the use of boosters.

This guide provides expert instruction from Randy at AT3 Tactical on installing muzzle devices on AR-15 style rifles. It covers essential tools, understanding thread pitches (1/2x28 and 5/8x24), and detailed techniques for using crush washers, lock nuts, and shims to achieve proper timing and secure installation. The instruction emphasizes matching the device to the barrel's specifications to avoid critical issues.
