Video from the Geometry and Vector features the VFC P320 X-Carry that comes with a distinctive aluminum slide. The video captures a demonstration of the gas blowback pistol’s rapid-fire capabilities, highlighting the mechanical cycling of the slide and the distinct auditory feedback with each shot. For those who enjoy the clatter of metal on metal, the aluminium construction seems to provide a crisp response that keeps pace with a fast trigger finger.

Geometry and Vector recently put a Tokyo Marui Glock 17 Gen5 through its paces, featuring a full steel conversion kit. This build integrates a Guarder steel slide and frame components with internal upgrades like a TTI TDC hop-up chamber, a PDI 6.01mm inner barrel, and a 4UAD bucking. The result is a sidearm that replaces the standard polymer construction with a heavy, metallic finish and reinforced steel internals.

Geometry and Vectors assembled a TTI Pit Viper Gas Blowback Pistol using a selection of high-performance and durable components. Key parts of the build include the foundational 5KU CNC Aluminum Pit Viper Kit designed for the Marui Hi-Capa GBB Airsoft platform. Internal components for enhanced reliability and longevity feature several Army Armament steel parts, specifically the hammer, knocker, and sear, complemented by a Guarder steel Knocker Lock and Disconnector.

기하와벡터 (Geometry and Vectors), does a quick shooting test of the Archwick APC9K SD² made for B&T Air. The B&T Air GBB APC9K-SD2 is an officially licensed airsoft replica of the B&T USA's APC9K, which was selected by the U.S. Army for its Sub Compact Weapon (SCW) trials. 

In a video, Geometry and Vectors showcase their GHK Airsoft MK18 HPA system, operating at 300psi. This custom build features a GHK MK18 base, upgraded with a Samoon 7075 forged receiver, an ArtArms 140% reinforced buffer spring, an RNL improved hammer, a 202g RNL stainless steel buffer, an RNL mil-spec buffer retainer, and an EAR enhanced auto sear, all complemented by a RA-Tech SAI steel bolt carrier and the original nozzle.
