In mine, semi auto isn working(
And i have low quality details you can do a building kit for this gun

a very nice collection, works well, easy to follow and precise.

Amazing building kit. I pre-ordered this and got free shipping to New Zealand! The shipping didn't take very long either. The only downside to this kit is that the rubber band for the bolt breaks after a little while and I'm up to my last one. Overall the building process was fun, the functions of the rifle are great and incredibly accurate, as well as looking great as a display piece it is always fun to set up some targets and start shooting. I would recommend this build to anyone unsure of buying it.

It works moderately well, sometimes it gets a little stuck and fixing it is a little scary, but it usually works out. Also some of the bricks in the set were incorrect, but they're only decorative so it doesn't make that much of a difference, it just doesn't look as great as it could. Also it could just be my set that got messed up. Finally some of the rubber bands I got for the mechanisms aren't the same as the ones in the instructions so setting it up took a little bit of investigating but once again, that might just be my set that's wrong, but at the end of the day, the building process, which I'd say is the ultimate goal of buying this, was still really fun ^^

Had trouble building the, got a broken part, blow back kept jamming along with the trigger double checked every thing and nothing worked. When using the slide lock the whole back part just lifts up and the whole gun jams. The skin looks nice otherwise.
