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.

Probably many of you have heard of this by now since it was introduced early this year. For owners of the Tokyo Marui AKM Gas Blowback Rifle, they can check the Real Power Airsoft Tokyo Marui AKM GBBR AK Steel Kit if they want to uprade the metal parts of the rifle. The package consists of a full metal receiver and barrel with a muzzle device and sight. This is available at reputable sellers, mainly in East Asia, right now.

Another look at the HFC M11A1 Ingram which is a good airsoft machine pistol that uses Green Gas as power source. This spits out 20-21 BBs per second and has threaded barrel for M11 style airsoft barrel extensions. Hedis got one that has G&P Steel Kitt for a video review done in Korean.

Jeidanten show the mod kit made for the SIG Air Pro Force P320/M17 Gas Blowback Pistol made by VFC... "This video uses a simple and clear way to teach the disassembly and assembly of the SIG SAUER P320 M17 GBB TAITAN steel kit. If you have friends, you can buy the goods seen in the video on the official website of Jiedantian and open auctions."
