I just picked up an ATN 2-6X40 scope for a up coming new build.  I got it at a very nice deal and it seem like it will work out quite nicely.

I am now looking for flip up covers for it.  Anyone know where and what size to get.  It has a 40mm objective but the OD is 1.965" (49.911mm).

Also, any comments on the ATN's in general (is it a decent scope, pro/con)?

Try www.atncorp.com  and look in the accessories dept.

ATN  Daytime scopes, in my opinion, are an excellent value. You get many features for relatively little money. They are solidly built. Glass is good. Etched reticles and so on.

The only thing I don't like is that the larger variable scopes can add considerable weight to your rig.

The ATN scopes I own , I've bought from a local authorized dealer, to take advantage of the lifetime warranty that he personally offers if I would ever need to .
