A G&G GR4 G26 for trade is available. The only issue is that when I got it from the company a screw keeping the outer barrel in place was missing and I used a cold and heat resistant guerrilla glue to fix it. And it cause no performance issues and has worked great. Pneumatic blow back works great and can be disabled if desired to do so. The laser and LED in the handguard do work but I no longer have batteries for those. But it comes with iron sight, battery, and two hi cap mags. One of which is custom to the gun. Holo can be included if the gun offered for trade has a sight with it has well. holo works great and put fresh batteries in it. Red and green.
