Airsoft Magazine BB Speed Loader M17/M18

This is an adaptation of https://makerworld.com/en/models/1984569-airsoft-magazine-bb-speed-loader-with-funnel-glock for the Sig M17/M18

Description

An airsoft speed loader for SIG M17/M18/p320 that keeps the magazine spring down while you load BBs into the magazine. I've only tested it on a SIG M18, but it can probably work on other brands of airsoft M17/M18/p320, as they're pretty much copies of one another. There are other versions of this online, but this one comes with a funnel that makes it usable without a syringe style speed loader i.e. you can just dump loose BBs into the built-in funnel. 

Usage

• Pull down on the magazine spring fingernail tab a little bit.
• Insert the magazine to the speed loader from the bottom, making sure that the bump on the speed loader presses down on the magazine spring fingernail tab.
• Once inserted, push down on the speed loader until the magazine spring bottoms out.
• Load BBs into the funnel either using a syringe style speed loader or from a small bottle (as pictured).
• Give it a shake every few rounds to ensure perfect double stacking of BBs.
