Survival JP introduces the updated Essential G custom series (versions 2.0 to 2.1) designed for GHK CO2 gas blowback rifles. It begins with a demonstration showing the rifle hitting targets at distances of 20 and 40 meters. He notes that continuous firing causes a slight drop in gas temperature and velocity, which may require minor aiming adjustments, but highlights that the overall accuracy remains solid.

Survival JP shows the "Spectre" custom tune for the M110A1 AEG, designed to operate as quietly as a bolt-action sniper. He explains that this modification is specifically for large rifles that provide enough internal space for advanced soundproofing. Beyond just being quiet, the build is tuned for long-distance accuracy, capable of hitting targets at 50 meters with heavy 0.33g BBs, making it a specialized tool for stealthy players.

Survival JP does a detailed comparison between gas guns powered by HFC-134a (Freon) gas and those using CO2 cartridges, specifically focusing on two Glock 17 Gen 5 models from Tokyo Marui and Baton Airsoft. The comparison covers several key aspects including cost and fuel efficiency, muzzle velocity, recoil performance, grouping (accuracy) at 15m, and initial purchase price.

Survival JP shows his custom electric airsoft gun, a modified VFC MK18, with insights from airsoft enthusiast Morohoshi or more known as Mister Moro. The gun, built on an affordable E&C model, features a robust metal exterior and impressive trigger response. Morohoshi's testing reveals flat trajectory and accuracy at various distances, including a direct hit at 40 meters. The full-auto mode demonstrates a tight grouping of shots, indicating high control.
