  • Barska SKS Electro Fizzles

    First off, did a superb job in getting this item to me and its price was better than anyone's else so the 2 star rating for this item should in no way reflect poorly on Overstock. Overstock gets a 5 from me. I was a little leery about purchasing a Barska scope as they often have poor reviews. However, I needed a short scope to fit a Choate Side Mount on a Norinco SKS rifle. I like the Choate mount as it allows me to use the iron sights as well as a scope. I wanted a short scope so I could use the stripper clips and I did not want to put a $400 scope on a $100 truck rifle. The Barska appeared to fit the bill. The scope arrived in a new box wrapped in plastic. Inside it was not protected well but nothing appeared to be damaged. A Bikini strap lens covers came with the scope. The lens covers are tinted plastic. The lens covers are coming in handy but after two months the elastic is becoming worn. The covers themselves are getting marred but the lens are still new like. No instruction manual was issued with the scope. There was a Technical Update page regarding parallax view and images of the SKS reticle itself. The images were pretty detailed as far as indicating the MOA's for the various reticle markings. However, there were no instructions regarding its use. I have used the reticles to measure known distance/known size targets and they appear to be accurate. At the bottom there are measuring lines # 2 and ending with 10. I am assuming this to be used for measuring 2 meter high targets from 200 - 1000 yards but I am not positive (no directions included). I contacted Barska directly several times trying to get additional documentation on this scope and they failed to respond to any of my written or e-mailed requests. Likewise telephone attempts were fruitless. Once mounted the first problem was I still could not use the stripper clips. This is not a reflection on the scope's quality -- its shape and the limited rail slots on the Choate mount just prevents it being slide back the extra 1/2" I need for stripper clip use. I can remedy this by adding a rail extension (which will increase the scope's height by about 1/2"). BTW, I purchased a Blackhawk Check Pad from Overstock which fits the SKS nicely and allows good check weld as well as still allowing iron sight use. I have beat and banged this scope around for the past couple of months. I just cleaned the SKS and afterwards did a thorough check on the scope. Everything appears tight. I used Weaver scope mounts and they are still secure. The reticle is not moving about inside the scope. The view through the scope is still as clear as it was on day 1. The scope has a few dings (from 2 months of use and from a homemade shell deflector I placed on it) but appears to be handling it well. The "click values" are not marked on the windage or elevation turrets. This hinders the zero in process. The clicks for the elevation turret are nice and crisp. I routinely run them through the entire spectrum and back just to check them. The windage turret cover cap must be removed and a flat object must to be used to turn it. Again, without click values and having to remove the windage turrent cover makes the zero in process slightly painful. The top elevation turret lock down screw keeps backing out. This is making it hard for the scope to keep zero'd in. Likewise, moving the turret in the up direction indicated on the turret cover makes the reticle move downward. As I mentioned above, I just cleaned the SKS and checked the scope. I bore sighted the SKS prior to reassembly and the reticle was again way off. I have bore sighted and then fine tuned zero'd this scope 4 times over the past couple of months on a 100 yard target. I get it to where I need it. I make sure all is tightened but the very next time I go to use the scope its off the 24" X 24" target and I again have to do the bore sight and fine tuning process. The Barska SKS scope makes a pretty decoration for my SKS but I am able to use the iron sights more effectively than I can this scope due to its not being able to hold zero.
