AK standard rear sight vs. Krebs Custom peep rear sight

Have two AKs, an Arsenal Inc. of NV SAM-7 and an Armory USA/Global Trades AMD-63.  Both came with standard AK rear sights.  At 25 yards, the sights are easy to use, at 50 yards it gets pretty blurry after about 5 minutes of use, and at 100 yards it is blur city from the get go.  I can get decent accuracy even with the blur (2-6 MOA).  I would called it a “managed blur”.  The managed blur being I have to work harder and squint more than say an AR-15 sight to get the accuracy required for COM shots.

I put a Krebs custom fixed peep rear sight on the Arsenal to see if I could get rid of the managed blur.  Ordered it online from their web site for $49.95.  Received it a couple days later.  No issues, no problems.  Putting it on was tough but got in on after 5-10 minutes.  It did come with good instructions.  Is just as sturdy and rugged as the standard rear sight.  

I have shot the Arsenal (rear peep sight) and AMD-63 (rear standard sight) together at both 50 and 100 yards.  

At 50 yards with rear peep sight…

- did not experience any blur what so ever, even after 2.5 hours of shooting
- was able to keep tight groups longer than rear standard sight  
- did not see any increase in initial accuracy

At 100 yards with rear peep sight…

- did not experience blur after 2 hours of shooting until the very end last 30 mins
- was able to keep tight groups longer than rear standard sight  
- did see some increase in initial accuracy perhaps 2-3 MOA vs 2-4 MOA from standard rear sight.

Bottom line, very happy with the purchase, it helps light years with the “managed blur”.  Plan on getting one for the AMD-63 for X-MAS.
