This is an MTC Viper 4-16x50IRS with illuminated reticle which I had on my HMR for 3 years. In very good condition but for a few tiny marks where the black paint has rubbed off around the edges of the turret caps.
The scope works perfectly well and holds zero etc however it has a problem with the lock on the windage turret. The turrets are meant to be locked and unmoveable when pushed in. The elevation turret locks fine but the windage turret doesn't lock... you can still turn it when it's in the locked position.
The clicks are still positive and there is a scale on each turret which can be adjusted so the problem above can be mitigated to an extent as you can set the scale to show zero so it's obvious if it has moved a few clicks. Typically when I contacted MTC it was just outside the old 3 year warranty and the price they quoted to fix it was not viable!
Obviously this issue isn't ideal if you have the rifle slung over your shoulder at night with the turret potentially rubbing against your back, but the scope should still be perfectly good for general target use etc.
Hence offered here for just £60 inc postage
Supplied with box and some other bits that came with it... sunshade, large paralax wheel, flip up covers and instruction book
