Jaeger Precision comparison of three recoil springs: the stock Marui, BAVTAC 115%, and Bow Master 130% for the Tokyo Marui AKM/AKX airsoft guns. Through firing demonstrations with different AK models, he notes the variations in cycle rate and overall feel each spring offers, helping his viewers select the best option for their preferred performance.

Jaeger Precision conducts troubleshooting of a VFC G36C V2 GBBR, which initially underperformed due to internal restrictors. Despite removing these components and significantly increasing the gun's power, issues like magazine choking and double feeds persisted. He points out the internal bolt components, including an unusual plastic restrictor, and seeks community input to determine if the gun's setup is standard or modified, aiming to resolve the remaining problems.

In this episode of Jaeger Precision, the Northeast Airsoft Mini Uzi GBB is subjected to the "Jaeger Test," firing multiple magazines to evaluate its performance. According to hims, whilst the Mini Uzi has a cool aesthetic and mostly steel construction, its performance is lacking. Semi-auto fire experienced issues, and full-auto, though rapid, isn't efficient. Magazines don't hold much gas, leading to gas expulsion and the need for frequent re-gassing.

Jaeger Precision reviews the VFC G36C GBBR, a licensed gas blowback rifle from VFC and Umarex. He starts with an unboxing and examines the rifle, showing its licensed markings, polymer construction, ambidextrous controls, and easy disassembly. He tests its performance, noting consistency in dry firing and chrono testing, but also issues with full-auto performance and gas dumping. He expresses skepticism about VFC's full-auto reliability based on comparisons with his other gas blowback rifles. 

Jaeger Precision shows the installation of the KPYK Ukrainian handguard unto a Tokyo Marui AKM GBBR. Initially, he encounters fitting issues because the handguard, intended for GHK and LCT models, requires significant modifications for the Marui AKM.

Jaeger Precision walks us through the conversion of an Ares M45 X-Class airsoft gun to use a Polarstar Jack HPA engine. The conversion faces challenges due to the unique gearbox design, particularly the ambidextrous fire selector and hall effect sensor system. Modifications include adapting the Polarstar's trigger board, reassembling the gearbox, and modifying the pistol grip and stock. After assembly, the gun successfully fires with a faster rate than before.

Jaeger Precision chronicles the customization of a new Tokyo Marui AKM, focusing on the detailed installation of a KPYK stock. He disassembles the rifle, comparing it to his previously modified AKM, and showcases the new stock's features like its adjustable cheek riser and folding mechanism. He expresses satisfaction with the upgrade, setting the stage for future modifications.

Jaeger Precision uploaded a video to help guide in upgrading a hybrid AAP-01 airsoft pistol with a HPA lower kit, enabling it to use ARP9 magazines. He demonstrates the assembly process, including converting a spare upper receiver and noting the need for additional parts. A power test is included, showing the upgraded pistol's performance and discussing plans for an upcoming airsoft game.

Jaeger Precision does a "Jaeger Test" of the Well Pro AK-12 gas blowback rifle. He puts it through its paces in a 10°C room, using propane and various BB weights. Despite a minor "sticky bolt" issue, the AK-12 impresses with its smooth firing on both semi and full-auto, reliably feeding rounds and detecting empty magazines. He praises its realistic sound and describes it as a modernized, joy to shoot AK, strongly recommending Wellpro continue developing this platform.

A look into the guts of the Salvo Precision Spear LT 11.5" MWS gas blowback rifle by Jaeger Precision. He guides viewers through each step, offering advice on detaching components like the stock, handguard, barrel, receivers, bolt, trigger box, and quick-detach points.
