Double Bell Metal Slide Lock Kit for M1911 GBB Airsoft Pistols, Black

Worn slide locks and plastic internals are the first things to go on a high-round-count M1911 GBB. This Double Bell parts kit replaces the most stress-prone components with full metal versions, so your pistol keeps cycling when the factory plastic starts to slip.

What's in the box. You get three pieces: a slide lock, a hammer, and a magazine release. All three are full metal, which matters on a gas blowback where those parts take repeated impact every shot. The stock plastic equivalents can wear smooth or crack after a few thousand rounds, especially if you're running hot loads or CO2.

Fit and compatibility. This kit is built for standard M1911 GBB platforms — the Tokyo Marui dimension that most aftermarket parts follow. If your pistol is running a full metal slide and frame, these internals are the logical upgrade path. They're also a straightforward swap if something broke mid-skirmish and you need a field fix.

Weight and feel. At 1.05 oz for the set, you're not adding noticeable mass. The difference is in the action: metal parts seat more consistently and don't deform under repeated hammer strikes. The mag release and slide lock should feel crisp rather than mushy.

Before you install. You'll need basic gunsmithing tools and a clean workbench. M1911 disassembly is straightforward but precision work — take photos as you go, and keep track of small springs and pins. If this is your first internals swap, watch a teardown video specific to your pistol model first.
