EMG Zero Trigger for Barrett Fieldcraft and Tokyo Marui VSR-10 Airsoft Sniper Rifles

"Installed this on a CYMA VSR-10 (the CYMA 701) with an Action Army 90 degree piston. Fantastic trigger for half the cost of many others, but you may need to do a little bit of work to make it fit.
There is a part sticking up from the casing that prevents you from firing when the bolt handle is up, and it is too big to fit into the gun. (In the photos, it is the short nub right above the trigger itself.) It's a pretty pointless safety lock and everything works perfectly fine without it. In order to get it to fit, I just removed it. You need to open the trigger up to do this, and I would take pictures before you take anything apart in there. You may also want to get some sort of spacer to take its place so the tiny parts in the trigger don't wobble around with it gone.
Another issue when installing this is the CYMA trigger guard also does not fit with this trigger installed. Other trigger guards (without that fork in the front that fits into the trigger) will probably work, but may fit a little loosely. This trigger seems a little smaller than standard and it looks like you would end up with about a 1/4" gap between the trigger casing and the guard. I ended up 3d printing a new trigger guard.

The trigger casing and all the parts in it are well built and made of steel (except for the trigger itself and the safety, which are plastic). The trigger pull and the bolt pull is smooth and the 90 degree/zero degree system is much better than the stock 45 degree trigger. The price is half that of other 90/zero triggers (at the time of writing this at least), and while I don't have any of the premium triggers to compare, this one certainly does its job. Modifying it to fit was easy (and I'm by no means an airsoft technician), and certainly worth saving 50+ dollars.

"this is an amazing 90 degree trigger, perfect for low budget upgrade. i installed on my echo 1 m28 that as you know it's a vsr 10 disguised as a m24. to fit it the only thing i did was to drill the mounting holes from 3mm to 4mm diameter as the m28 uses M4 screws, and must enlarge the cocking safety lever window under the receiver.

and for the trigger guard you must use a file or a dremel bit to cut a bit of a corner so it wount bind with the cylinder take down pin

overall the quality of the trigger it's better than spected. sears and pins are steel, and the body seems to be a good quality pot metal. the feather trigger it's incredible, the entire pull up to the shot it's very smooth and doesn't hardens at any point.

"OK first off I'm new to sniper mods but if your buying this for a JG BAR 10 (vsr10/clones) you'll need to modify the trigger to fit ( I had to cut down the bolt catch/nub significantly and it's made of decent metal/not super easy to do with basic tools) but once modified it works perfectly and to save you time you must use a 90 degree piston with this trigger setup.
I highly recommend this for a vsr10 build as long as you don't mind modifying it out of the box.
