I have read the opinions and i have a genuine no4t, my veiw is a bit different, using a repro for feild use so an original doesnt get damaged.

I also have two of the repros both in brackets, both had problems with turrets. One for use on my no4t the other an L42a1 replica.

After repair no issues with either with 100's of rounds downrange. In fact the 308 has close to a k or more, they are clear and also have backlash issues. Apart from that my experience is they are ok.
