Input:
Question: How high above the cover is the top surface of the rail? Does the rail touch or sit on the cover or not?
Document: Install was fairly simple (it comes with instructions) and took only a few minutes.Rear "iron" sight on the rail is open top and fairly useless, it should probably be an aperture sight but I'm willing to overlook that fault.
It was hard to install on rear  do to removal of original rear  leaf but it was me since it was my first time doing this removal. I'm sure it would be easy for other guys having done it before.The rear part adjust back and forth to make sure it locks properly this is nice feature.I recommend this product for a budget top rail. You could use TWS system or something else but way more expensive. $74 w/ shipping is great deal.
I recommend this rail system to all AK owners. You can't beat the price vs value on this one.
Even fully secured the rail wiggles too much to be useful for real use. Others may have better luck but I am disappointed for the price after shooting about 100 rds through it.
which I like better because I can tighten them to hell. AND the rail should be 'see through' the middle real dissatisfied with the iron sight. Idk if the bb falling out is an issue for most but after one fix I shouldn't have to do another
If you were hoping for something like the Krebs Rail then I would suggest you look elsewhere. Also, if you want something which will have a usable rear sight then I would suggest another product. I actually did not like this and ended up selling mine. I am going to get an Ultimak instead.
i called customer service and they said it was because this rail was shipped from optics planet. i informed them it was in THEIR list of qualified items, they checked and agreed i was right and said they would issue a $20 credit when all items shipped. i got an e-mail stating a $10 "good faith" credit had been issued. my blood boiled!
If installed correctly and no damage to the AK rear sight holder, it is a very well made mount. It's nice and sturdy and is highly recommended. It places the scope where you want it and has held zero after a thousand rounds and a dozen cleaning. UTG pro rail is a good buy. Get yours now if you want a good AK scope mount rail.
That's why you need to adjust it and make sure it locks up firm and preferably use Loctite. Theres a reason they make this thing adjustable!!! Also don't tighten the allen screws like a gorilla, use common sense its aluminum and strips out. And comparing it to a Krebs rail is just ridiculous, if that's what you want go ahead its $310!! This is $90!
Nice quality product. The only reason it didn't get five stars is the rear sight sucks. If it was a peep sight easy five. I have had to completely take it off and reinstall it on the rifle several times for other stuff, not due to the rail itself and its still SOLID. Not sure how many times you can do that due to it being aluminum. But regular opening and closing via the button, no problems. I expect this thing to become very popular.
Answer: no
