Heavy duty for the $ - Falke LE 1x33mm 65 MOA Circle/2 MOA Dot Reflex Sight

I bought two of these. one had to be exchanged. would not brighten or darken. the replacement is good. the only thing about this thats a deal breaker is I have not seen it go to sleep. Thought its suppose to. second thing is it firgets to go back to last setting after you shut it off. you havebto brighten it each time. ither than that it takes a beating and keeps.on woeking. no loss of zero when dropped rifle and it kanded right in the sight. bent the cover protector a little takingnit off to reshape it was a pain as it was not made to take off. you have to just about dismantle the sight. on e straightened out. gap is good all the way around. works great no problems..great price on sale and a coupon.. whats not to like. good for my 450 Bushmaster 10.5" pistol!! takes the recoil fine. held zero and I shot three boxss in a row while testing upper.
