Thread: Nightforce Atacr Problem?

No it is internal - outside as new of course...cos basically is. Perhaps just caught right light. 99% sure not fungal.

I'm picking it will have to go back to nightforce mate I have never seem anything like it, deadeye dicks might help by sending it direct to wherever they get repairs done?

From experience you will fine dead eye less than helpful unless you purchased the scope through them.Just go direct with where you purchased it from or deal with nightforce direct.

looks like fungus, a problem with non sealed camera lenses...

Oh well, You get the odd lemon with the entry level stuff.

Helpful as ever?

Just because your gun room is bone dry doesn't mean the inside of the scope is.

True...hasn't been wet though, but of course may not have come to me dry.

You had better swap over to that big Zeiss and get cracking on the ELD-X load development. I need some free load data for the 260AI

Kahles or vx-6 now...

Sometimes when a lens (if multilayer) for the likes of sunglasses comes apart the first sign you get of delamination in either a tide line if its from one edge or these crackly lines as the adhesive is coming away from the two layers equally. Its much more usual to come away from one side than all sides at once unless the internal ring has let go. So no sounds or rattles when shaken?

Yes looks more like that than fungus to me...not having seen fungus before (on a scope lens).... but no rattles.

All it needs to do is compress the buffer its against to give it play to reverberate against so it's ok on one side and adherred on the other. Tell tale is it doesn't change in the safe but becomes more pronounced (compare photos) after firing a number of shots. what cal is it on currently?

260AI, round count just under 20. I read there have been issues with the new F1, will have a google.

OK good info with that round count I'd say given they are gas sealed with metal rings plus o rings etc what you may have is a partial lens failure due to a vacuum or similar force trying to suck the inner side of the lens off and this wouldn't have been viewable until after firing, so would have passed inspections at factory - and any other parts not cinched up against the lens had moved to their final resting place. As you say if its a machine issue at point of manufacture there'll be a few of these whilst the machine was out of tolerance. google and other forums will be your friend with this I'm sure...
