If your rifle is the newer production model, check the front/rear ring alignment, misaligned rings can put sideway pressure on the scope tube and cause it to fail faster.

I don't think the problem with the Mini-Guns eating scopes is the op-rod moving back and forth. I think it is harmonic vibrations from the whole firing process.

I also think if you put a Mo-Rod on your Mini-Gun you will see much less damage to scopes from harmonic vibration.

When I worked in the Aero Space industry (TRW) I had the opportunity to watch vibration tests on various electronic and electro-mechanical devices.

The devices being tested were powered up and instrumented for the tests.

When the viration table started operating, I thought the items being tested would fly off of the table, or surely stop working, as they started violently vibrating. It didn't ever happen that way. The devices would fail when the vibration was invisible to the eye, but could only be heard at a high amplitude pitch.

cheap Bushnell Banner 3-9x40 still solid after around a 1000 rounds on my 14. Great optics too.

I find this stuff very interesting, I don't really care if my mini 14 kills the Weaver 1-3x I have on it someday, but I'd like to understand why.

wahoowad, interested to see how well Weaver customer service takes care of you.

I've had an EOTech sight mounted on an Ultimak rail on my Mini-30 for about a year now. No problems so far....

My Mini-14 and Mini-30 both wear Burris scopes. They are the only manufacturer who claims that all their rifle scopes are sturdy enough even for air rifles.

Good info. So basicly you are saying get a rubber hogue stock, accu strut, buffer, and muzzle break? anything I missed before I get out the blue money card? lol

I think an op-rod buffer and a barrel vibration dampener, seen mounted on many Mini guns, on this forum, would suffice...

I have both the Mo-Rod and Mo-Reaper installed on to my Mini 14 as well as a .050 bushing and Hogue Overmolded stock. Currently using a Vortex Crossfire II 2-7x. Hopefully it won't break down too soon.. if so, there's a lifetime no questions asked warranty on it. Me, along with several other people has noticed that my Mini definitely feels like its got a softer recoil than the ARs we've brought to the field.

I've only put about 400 rounds through her so far and there hasn't bee any issues with the scope yet. Too early to tell. I think if my scope does die out though.. I'll send it back for a replacement as mentioned, sell it, then get either a shotgun scope (I don't shoot that far out anyways), or just run it with irons.

About the op slide slamming into the gas block, I read an article in which the author said the most accurate Minis he tested at the Ruger factory were ones where there was a slight gap between the op slide and gas block, so they never contacted each other while cycling. This could make a scope last longer by removing at least on source of vibration and shock.

I was joking. Im not really interested in turning my mini into a bench rifle. Mobility outways (slightly) accuracy for me. I have not yet shot my tacticle 580 series mini, but I hope that it does not chew up the nikon P223 point blank I got for it. Luckily lifetime warranty comes with it.

If you are going to put a scope on a Mini-14/30 you need to spend the money on quality built scopes. I also use UltraDot red dot scopes made in Japan.
Have you had good luck with Ultradots on your Mini? I use them on two of my 10/22s.
