Home Forums Hunting & Shooting Hunting Optics 1.75-6 pentax lightseeker specs please

Anybody know the weight of one of these? Also, really looking for measure eye relief on 6 power. Hoping it's close to 4".


Looks like a cool old scope.

Should be same as the Burris of the same vintage….they were basically the same scope, IIRC.

I have one that I can dig out. They are not lightweights.

I have one at home I can weigh, but it will be a few days. I don't *think* the eye relief is quite 4" @ 6x, but I honestly can't remember for sure.

Thanks guys, hard to find any specs on this scope

Have you tried looking for the specs on a Burris Signature 1.5-6? It’s virtually the same scope. I have one that I’ll try to dig out this afternoon and check eye relief using JB’s method.

No luck finding specs, looking forward to some info. Thanks.

Just checked, mine is the Burris Signature 1.75-6X that, as measured via flashlight, has a pretty constant 2 1/2" of eye relief. It weighs 14.8 oz. Dug around a bit more and found the original box and all original contents. One item noted in the "features" is the claim of constant eye relief. I have a receipt from Burris dated 1/3/02 where they corrected parallax under warranty for me.

Thanks edm. Geeze, gotta be better than 2.5" eye relief, is that possibly a typo?

Anyhow, this is the actual scope:

I had a Burris Signature 1.75x6 and even on 1.75x the eye relief was not as good as 4x. IF you find some specs consider the stated eye relief is from the rear lens.

Eye relief on my Signature 1.5-6x is 2.89" at 6x. Weight is a hair under 15 oz.

I measured from the scope body (what will bite you) not the lense. To the lense adds ~1/4".

Darn edm, I'll double check it when received, but looks like that pentax is going on the .22.

Those Burris aren’t known for eye relief if it’s in fact the same scope.

Ended up weighing 14.7 oz and the scope was 2.5" from my eyebrow.

It went on a 22 lr

I have 2 or 3 of these scopes. I don't recall the eye relief. I had thought about 3". I used one on a 338 Winchester and 375 H&H for awhile. I recall the 338 off the bench, with a little stock crawling could get close to skin contact. Definitely a compact little scope.
