[Set] Strike Industries Licensed M870 shotgun replica - Black [EMG] + Mini Pistol / Carabine Red-Dot Sight - Black [JJ Airsoft]

Had this on a Shark full-auto pistol for a while and it worked fine until one day while shooting the glass just flew off. It wasn't damaged or anything just detached from the frame - managed to put it back with superglue and clean any mess on the glass with acetone, hasn't moved since (over 1000 rounds since then). To be fair, I had dropped it a few times before that, and the full auto blow-back on that pistol is quite violent, maybe on a NBB or at leas a semi-auto GBB it would be fine.
Apart from that it is decently build, and I haven't had any other major issues.
Overall quality is not amazing but not bad either - for the price it is decent.
The buttons are easy to access and it even remembers your brightness setting once you turn it off and back on.
The lowest brightness setting is still too bright, but sadly most red dots are like this.
The protective cap is made from clear plastic and if it is clean you can use the sight without removing it. It has an ear at the back for a string, but it is also a zeroing tool.
Comes with mounting plate for a pistol. Just remember to use the shorter set of screws when mounting it to the plate and the longer ones on the rail mount (comes with two sets). The screw that holds the plate to the pistol needs retightning once in a while. As long as it doesn't get too lose it keeps zero.

Spectacular external design! Nice shots on the field, very happy to all!
Marui cartridge compatible.
Little heavy weight but acceptable….
Fast shipping and top service

It's a pump action shotgun, and it does exactly what the box says. As with all guns it has been test fired before shipping so you know it works when you take it out of the box.

The front bit of rail was a nice addition, and the heat shield on the barrel gives it a distinctive look.

The only thing I noticed was the rear sling mount is a bit narrow, but 30 seconds with a circular metal file fixed that. This could also have been that the particular sling that a chose was on the larger side!
