The Chinese RWS scopes have tubes of two pieces. Apparently they are glued into the cross-hair adjustment turret. A heavy recoiling rifle can break the glue seal and cause the tubes to separate.
This happened with a new RWS 450 scope on a new Diana 350.
The NJ based DNRWS folks told me explicitly that the 450 will hold up to the heaviest recoil. They replaced the broken scope. Will see if the new one can take the heat.
Well my tuned Model 350 arrived yesterday from Russ Best. I strapped on a new RWS 450 scope and proceeded to test pellets for best group.
After 30 shots, the lens in the eyepiece broke loose. I took the ocular portion out (just unscrewed it), tightened the tension ring thing that holds the lens in place, replaced the ocular portion into the rest of the scope. After two shots, it broke loose again.
I sent a note to www.dnrws.com about replacing the scope. Will keep you posted on the result. This is the third time an RWS 450 scope has broken on this rifle.
....I was looking at an older Diana rifle the other day - and noticed its' RWS 3x9x32 scope looked exactly like an old Bushnell Sportview - except it had different labeling - otherwise near identical - are these two scopes the same Chinese item under the skin? - HV
I've been testiong a Diana scope 4X32, non AO, simple, very robust scope in my 350.
After 300 shots, no sign of breakage yet. Nothing loose, nothing coming undone.
Very favourably impressed with this scope. Dunno what scope it is or where it was made. It is slightly less luminous than the BSA 4X32 (my other favourites in hard-kicking rifles), and both are less luminous than the old Swift 2-7X32, but then we should not compare US$70 scpoes to US$250 scopes.
Try to find out if the RWS scope is the same as the Diana scope as sold in Germany.
