I plan to compare this weekend. I'll start a new thread.

I just found this ARFCOM video from Shot Show, nice look at the FSO and reticle details:
GRSC FSO Full Spectrum Optic - SHOT Show 2019

A couple of comments:

I live not too far from Ed, so I met with him a couple of times over the last several months to take a look at the prototypes of this scope.  The scopes I saw are not the same as the production ones will be, but what I saw looked quite promising.  I will most definitely test the production scopes thoroughly.

The reticle is unique, but I am reasonably used to it (I still have one of the prototype 1-4x24 scopes from back when Ed tried working with Millett) and it works well.  I've shot out to 1000yards with the prototype and  I think it is good general purpose solution for AR platforms.

There was a question earlier in the thread whether there may be enough space in the market for two tiers of this design.  I think that there is, but there may be some interesting designs out there that could serve as a platform for Ed's reticle.  However, honestly, I would rather have Ed focused on this one for a bit.  This is a different way of thinking about reticles and I think Ed can reach a lot more people with a $550 Chinese scope and sorta raise awareness that this thing exists.  After that would a good time to explore additional platforms.

Also earlier in the thread there was a question about exit pupil diameter.  Exit pupil calculation of objective divided by magnification is not valid for the entire magnification range of the most scopes, especially of the LPVO designs.  The exit pupil of this scope is indeed 3mm on 10x.  However, on 1.1x it is most definitely not 27mm.  At lower magnifications, the objective lens is no longer the field stop and the effective objective diameter is smaller.  In practical terms, when I looked at a bunch of FFP 1-8x scopes last year, their exit pupils ranged from ~8mm (NX8) to ~12mm (XTR II).

I have not had a chance to measure the exit pupil on Ed's scope, but it should be in that same approximate range.  We can probably assume 10mm for now and when production scopes are here, I'll measure it.  If my guess is correct, the exit pupil is 10mm between 1.1x and 3x.  Between 3x and 10x it can be calculated by simply dividing objective diameter by the magnification.

Thanks, that's why I asked since in the real world, exit pupils are always all over the map when comparing optics and a bad exit pupil is usually a deal breaker for me, ie. the primary Arms 1-6 and 1-8.

Bump - with question.

It was rumored that an offer of "if you buy the 1-6x, then we'll give a 1.1-10x for free" might be in the works/on the table?  Any truth to this?

I'm definitely interested...

Hoping to see a glowing review from LRRFP52!

1.1-10x30 FSO at no extra charge.
This will be a limited promotional if it works out.
I will keep you posted.

I hope to get a sample of the 1.1-10 FSO out to LRRFP52 toward the end of next week.

I'll be buying one of these (the 1.1-10×) even if this deal doesn't happen.
If it does, I'll be one happy camper.

 As I am getting older I'm trying to delegate more of the administrative part of the business to others.
 This will allow me more family time and also more field/trigger time.

Fred has been a very big help to me in the past with other projects and the T&E of CRS and FSO.
 I'm sure he will do a good job in his new role.

Fred will be posting here on AR15.com to keep interested parties updated on the status of this FSO project.
 He will also handle the GRSCINC website, social media, and individual internet sales thru the GRSCINC website.

I will continue to post here on AR15.com as needed.

Update on delivery status for the 1.1-10 FSO:

At the Shot Show I was told by my manufacture that we would have the first batch of production scopes by the end of February.

I am now told that there was/is a delay and I will not receive scopes until the end of April. Disappointed? So am I, but there is nothing I can

do about this. I just hope we get the scopes at the end of April as stated.

Also I was told by my FSO manufacture that if we wanted daytime bright illumination we could only have one color, red or green. Therefore the FSO illumination will will be green.

I will instruct Fred to start a list of potential buyers at the end of this month. We WILL NOT take preorder deposits or payment for scopes we do not have.

Thank you all for your interest in this product.

@GRSC

Ed - thank you for the response and clarification on the potential promotional deal.  I'm very interested and I'm in no hurry, so the Feb-Apr setback is not a concern to me.  I know it's disappointing for you, but I believe others here will be patient as well.

What made you decide on green over red for the illumination?

@GRSCfred as well

Any more updates? Patiently waiting.

Wow, what a coincidence-I was trying to look at the GRSC site this morning but it was basically non-functional-didn’t know if It was my IPad or what.

Ed-I’m really interested in this 1-10x scope for a 2 gun/all around build I’m finishing up. I have to say that i’m somewhat put off with the reticle being a rifleman’s best option but it’s calibrated for .308........ like most guys in the military, I’m shooting 5.56, not 7.62..... maybe I’m overthinking this as a consumer but it doesn’t make a lot of sense (to me) to buy a scope for my rifle that is intended to make hits out to 1000-1200m but is not calibrated for my rifle at that distance.... I would bet that the trajectory with the .308 load your reticle was developed for starts to deviate from 5.56 ammo around 600m. And at that distance a 3x BDC ACOG like a TA33 is not far behind in potential for getting good first round hit probability.

Maybe I’m not looking at this right-I’d love to have the capability this scope would offer if it were calibrated for 5.56........ hardly anyone on the consumer market shoots battle rifle cartridges anymore.

I like everything about this scope, except the reticle doesn't fit my use very well. I'd want to use it on a competition rifle for 3 gun and a crosshairs reticle with an illuminated center dot would be more useful on bay stages where the targets are closer and a lot of times have no shoots covering g part of the target and I'd need a smaller aiming point than the horseshoe. I will keep tabs for possible future reticles though.

When the GRSC 1-6 came out I bought one for 3 gun. Same thing the reticale just did not work well. About 6 months after I bought the GRSC the Razor came out and I bought one and never looked back. The GRSC was on EE the day I got my Razor.

After some of atibal's recent actions I prefer to spend my money elsewhere. My current plan when I eventually move up to Tacops is the Vortex viper 1-6 but I'd much prefer a FFP scope like yours.

I’d be all over this but sorry, don’t care for the reticle. If you had a ballistic dot similar to the Burris 1-8, then I would hold off buying the Burris. I have a vortex scope with Chinese glass that’s pretty good so will assume your will be better. The other manufacturers will have to step there game to compete with yours. Good luck.

Just watched all of your vids you posted. Suggest anyone complaining on the horse shoe reticle watch the videos. Am now reconsidering a purchase. Curious though about price with current trade fighting between USA and china. How are you able to offer at that price? Tariffs not an issue? Since am wanting a new scope for my Grendel, will wait for LRRPF52 review before deciding.

Here are some pics on 1x and 8x:

This was with an ARD on the objective, so the glass is actually pretty clear.

The box of dots are Mils with 5 mils marked with hashes.  The reticle is very fast for getting on-target without breaking sight picture and your windage tracks are already there.

I would like to put a reticle in this 1-10 scope for use in 3 gun competition. I am open to ideas.

In the mean time if this scope seems to fit your needs, Atibal has the same scope with a different reticle and different W/E  turrets that might suit your needs.

You ask a valid question. How can I sell this scope at  $575.00?  I run a very very very small company with very low overhead. Also I have been working directly with the OEM company to develop/ produces this scope, no middle man. Also look at my videos. To say they are amateurish would be a generous compliment. That's me, Fred and my kids doing the videos website etc. Point is, the more I spend on development and advertising will add to the cost of the scope. I work very hard to keep this at  a minimum. $575.00 does not include a lifetime warranty. You will
have to pay extra for that. I have worked very hard to develop a good product that I can sell at a very competitive price.

The scopes are supposed to ship today. I will be sending a scope to LRRPF52 as soon as get them.

For what it is worth, I have the Atibal scope here and I will borrow one from Ed as soon as he gets a few in.

I am not crazy about the Atibal reticle and I really want to see how these two reticle designs look side by side.

There really aren't a whole lot of decent FFP scopes out there in the sub-$1k range, but that competition is heating up now that Burris has announced its RT-8.

With the existing options, I am baffled by some reticle concepts out there.  I do not agree with Ed on everything, but his reticle is intelligently designed and he can comfortably articulate why every feature of it is there.

I swear a bunch of the reticles I see out there look the way the look because they wanted it to look different, not for any functional purpose.

Thanks for the heads up on the Burris RT-8. If they stay with the same reticle as the RT-6, they can keep it. I’m holding off until reviews are posted about this scope before deciding.
