No its an aluminum housing. The reviews mentioned it was blurry to look through.
Mine was. Just out of focus. I started to unscrew the eye piece and it quickly came back in focus.
My remedy was an o ring. Took the eye piece off and put the o ring and then put the eye piece back on. When I tightened it back up it was crystal clear.
4x magnification is just about right.
Ive put a few hundred rounds and it hasn't lost zero or drifted at all.
I think the one i got was around $80. Beats the real one for close to 1000.
I had to get a rail riser and mount it kinda silly far back, but that where it lights up for me. Thats means it right, no matter what anybody says.
Heres the reticle I have against a white wall.
I was ringing the gong at 800yds with 7.62x39.
If you look at ballistic charts, thats just off the far end for that round.
Impressive barrel on that ruger.
Now i just need someone to print me a magwell for AK mags.
Ruger makes one, but always "out of stock".
I could use mini30 mags but they are also hard to find.
