Question: Can u use this for a crosman airmag C11?
Document: This is not a bad sight. It does have the battery bobble in side the sight but it is great for wars I do wars but over all it is Perry good u should get it
This sight makes my shotgun look so good. I sometimes forget to turn it off and I still haven't want there the battery they give u in the sight. For the price and you get a new battery I would go for it
Doesn't work for all models. But it was fun and he was able to use it on his friends version.
looks good before you try to use it,cheaply made, very flimsy, can't be adjusted, absolutely useless, had to return it.
Amazing one of the bests scopes ever works great with any gun i use it wit UTG Everblast CQB Special Ops Airsoft Shotgun
This sight is so accurate. i bought it and it came in five days. I put it on my Crosman Stinger R39 and it is now the most accurate gun that i own. its really cheap for what the product really is. i recomend this for backyard airsoft rather than like proffestional and stuff because it is only plastic. i love this sight and i hope you do too!
You can even use it on a real rifle!But anyways , the swiss arms sight (with an m4 w/ front sight) cant look over the front sight of my m4 , tried adjusting it and everything !Hope this helps!! !
Worked as a toy pretty good, use on airsoft. Then one day it wouldn't turn on in the 30-60 day range. Just quit, checked everything, just dead. I'd skip this unless you just need cheap external prop
Exterior: This is made primarily of cheap feeling plastic, and I'm always afraid I'll break it if I bump it against something. The adjustment dials are very loose and I keep having to recalibrate it, as they get turned accidentally just from normal use.
I got this for an airsoft M4 just to give it some extra detail. The crosshair optic does light up and it came with a battery already in it as well as an extra battery. I don't shoot airsofts I use them as props. A little paint or silver sharpie and this thing works fine.
Answer: yes
