Combloc GAT BATTLE! RPD vs PKM! 💥

This video from Shot Show 2026 provides an in-depth look at new and surplus firearms from Zastava Arms USA. Key highlights include discussions on M70 parts kits with differing receiver thicknesses, the historical significance of trench art on surplus rifles, and the functionality of Zastava's grenade launching spigots. The review also covers the M57 surplus pistol, a new M90 configuration with a pinned and welded flash hider, a .300 Blackout M85 variant, and the highly anticipated semi-auto M84 (PKM). The information is presented by Ranko, a representative with deep knowledge of Zastava products and history.

This review compares the Soviet RPD and RPK light machine guns, highlighting their shared 7.62x39mm caliber and bipod features. Key differences include the RPD's belt-fed, open-bolt operation versus the RPK's magazine-fed, closed-bolt system derived from the AK platform. The RPD is noted for its dedicated LMG feel and heavier weight, while the RPK offers more AK-like handling.

This video provides an expert look at the semi-automatic Zastava M84 PKM, a firearm based on the Russian PKM design, chambered in 7.62x54R and featuring a heavy barrel. It also highlights the Zastava AK Suppressor, claimed to be the lightest and quietest in the U.S. based on Pew Science testing, with compatibility across several Zastava models. The firearm is currently awaiting ATF approval for the U.S. market.

This review of the Chinese RPD at the range highlights its surprisingly high rate of fire and manageable recoil, despite significant vibration affecting sight picture. The RPD's design prioritizes short bursts with a heat capacity around 300 rounds and a fixed barrel. While controllable with its intermediate cartridge, off-hand shooting is hindered by ergonomics, and the weapon may feel over-gassed.

This review delves into the RPD Light Machine Gun, highlighting its lineage from the DP-28 and its role as a belt-fed weapon in 7.62x39mm. The Polish-manufactured model features a flapping lock system and a fixed, chrome-lined barrel, but lacks a quick-change barrel and has small, overheating handguards. Its 100-round drum-fed belt system is compared to other historical weapons like the BAR and MG42.

The KvKK 62, Finland's squad automatic weapon counterpart to the RK 62, is a rare 7.62x39mm light machine gun. It features an RPD-like push-through belt feed but a Bren-style tilting bolt. Despite a high rate of fire, it suffered from reliability issues and was eventually replaced by the PKM.

This video demonstrates the proper loading technique for the M1 Garand's unique En Bloc clip, emphasizing the step-by-step addition of .30-06 Springfield rounds. It highlights how the clip functions like a magazine's feed lips once partially loaded and concludes with the iconic 'ping' sound upon ejection. The content is educational, showcasing the mechanics of this classic WWII rifle.

This video showcases a Beretta-made FKF M1 Garand chambered in 7.62x51mm NATO, featuring a modification to prevent the 'Garand Thumb' injury. The host demonstrates the rifle's unique safety feature, its semi-automatic firing at steel targets, and the ability to manually trigger the iconic 'ping' sound of the en-bloc clip ejection.

The C96 'Broomhandle' Mauser is an iconic pistol known for its unique wooden holster that doubles as a shoulder stock, making it NFA exempt. It features a 10-round internal magazine fed by stripper clips and fires the 7.63 Mauser cartridge. Select-fire variants exist, and its tangent rear sight is graduated to an impressive 1000 meters.

The GM6 Lynx, nicknamed the 'Handheld Howitzer,' is a bullpup rifle chambered in .50 BMG. Its unique long-recoil operation is demonstrated through mechanical sounds as the barrel extends, bipod deploys, and a 5-round magazine is inserted. The rifle features a compact design for transport, with a visible 'LYNX' logo on its muzzle brake.
