|Hands Down, This is a Superior Quality Produxt, My Gun Is Stainless so I have the Stainless Version of these Mounts which lock up secure/tight & look highly polished, just like the entire gun for that matter with the exception of the more dull/plain stainless magazines but theyd polish up easily to match if i hit them with some Mothers Polish & a Rotary Tool loke yhe ones used yo restore headlights commonly or the type that helps polish wheels made by Mothers- i do believe its calked the Powerball, i suppouse a Dremel would be fine if you stay patient & dont burn itburn the metal & it usually turns black or some level of distorted color especially when you turn that dial up & let it spin by trying to go too fast. To the Point- When using on my .223 Ranch Rifle 196 Series, 2002-2003 Mfg., i mounted my new 3-9x40 Top Name Brand Scope and Everything is Perfect EXCEPT, I swear it never fails, nothing is simple the fact that when mounting the Scope and Securing It I seen that the Raised Round Area on the Cented Heatguardi guess? was sticking up just enough to kerp tge scope from being perfectly level- this is nothing some minor filing, sanding, or something like that wont cure- I wouldnt break out anything electric like a Dremel or Sabder Because You Can Ruin Your Heatguard by sanding a hole through it in a few quick monents with a Dremel or Similar Tool. You guys know nothibg is ever simple with gun parts, car parts, computer parts, the dryer orcwhatecer but its nothing to worry about- patience will set you free, just be careful & take it slow! And, If anyone us thinking, Hey Dummy, Get a Set of Large Rings & You Wont have that Issue. Maybe do, but a scope should be as close to the barrel as possible, with nedium rings its 1/8-3/16 or 3-5mm away from the barrel so id trim it because itll be perfect & extremely close to the barel, nobody will ever see itre-paint it black if youre worried, but if you use Tall Rings Vs. These Medium Rings The Scope will Un-Necessarily be about 7/16-1/2 Too Tall If Not More, Perhaps this would allow you to use your iron sights with a scope mounted too buy i kinda doubt it, honestly if so, Id scrap my Argument & go with that as i find nothing more comforting than my sights zeroed for 75-100 Yards & My Scope Zeroed to About 200 Yards so I have the Ability to make quick shots at closer targets & a magnified scope at about 6Z-7X at a bitclonger Range If Possible, It may work out, well have to check out the Forums, but I do have a bit of lingering doubt, well see, if anyone has done this to your Mini 14, Mini 30, or 300 Blackout Version Please Educate Us! Thanks Guys, I hope I could help someone somehow, but i realize that wasnt exactly my most brilliant display of expertise, but its good food for thought, come on- give me that much!
