is anybody using these?

I can't say much about that mount. My Experience with no drilling mounts is only with pistols, and they work ok on those, but make the sight a lot higher then I like.

As far as red dots, you get what you pay for. I've played with quite a few brands, and the two best in my opinion are the Vortex Razor, and the Leopold Delta point pro. The only down side to these is the battery, but both can be changed without removing the sight from the gun. There are a few that work with rechargeable batteries and a solar panels but the battery life on these micro dots is really quite impressive, even turned all the way up, and extra batteries are cheap and don't take up any room in a pack.

If it was me, I would go with a Vortex because their VIP warranty is second to none. And I would look for a mount that fits that sight directly instead of using the rail and adaptor because it will make the dot much higher, more like a scope, where as mounted on a mount designed for the sight it's much lower and will feel more like shooting with irons.

My first choice for a cheaper dot would be the vortex Venom followed by the burris fast fire 3. Both of these dots are a lower profile and smaller then the Razor or DPP. A small window is fine on a rifle, but with a pistol the bigger window is better because it is easy to lose the dot if you do not get your indexing right, and it's hard to shoot fast and accurate. With the rifle, indexing is not as much of a issue. The Venom and the FF3 both have batteries they can be changed without removing the sight from the gun.

well, i would sell it but it was my first rifle(sentimental  ) and i put way back in the safe about 25+/- years ago. i retired her but as i (you) get older, i remember me, buck knife, rope, couple of bullets and my win m94, dancin' around the woods tryin' to get a buck or a doe  . 
i don't remember how many deer i killed but i remember my first buck. i have a 30-40 krag(1898 spr armory, given to me by my late grandpap) that i use. a 165gr ranch dog and h4198 that goes 1930fps will sure make the deer's day. but i don't have any 35 caliber and i do have a "donor" rifle!!! i know i shouldn't do it, but dang it......i want it!!!!!  besides, i can tell everybody that i have 35-30 winchester!!!

Greetings gentlemen, you too Hombre! Wanting to be part of the conversation but having nothing to contribute please allow me to ramble a bit on a subject remotely related a 35 cal lever gun. First I have to in shame confess to not having a 30-30 in any form and for this I hang my head in shame. I am a big fan of the cartridge and have great desire to spend time with one but still the pairing evades me. Many times have I begun the 30-30 purchase fund and reached the green light amount only to be distracted by other desirable examples of my weakness. This situation has repeated itself many times over and still the opportunity to devote some of what is left of my time to the pursuit of knowledge of the intricacies of the 30 WCF cartridge. So be it !
Now gaining .050" in caliber I have had great opportunity to explore the cast bullet possibilities of not only one but two fine lever action carbines in 35 caliber. These are both Marlin model 336 rifles but of different vintage. One is a waffle top 50's vintage woodsman carbine in 35 Rem and the other is a newer pre Rem 336 that was a 35 Rem but has been re-chambered to the standard 358 Win (not rimmed 356 Win) cartridge.
Both these guns give immense pleasure shooting because of their willingness to cooperate in placing shots in small clusters on target.
The 35 Rem was provided to us by a friend that wanted to gift it to us and was quite insistent that he be allowed to do so. Being a true friend I expressed that I just didn't feel right about accepting such a precious gift as it would make me feel as though I was taking advantage of our friendship. He asked if I would be more comfortable buying the Marlin which I was. He then set his maximum price at $1.00 and since it was obvious the situation called for some compromise I relented and now still have a tangible connection with a good friend.
The other Marlin in 358 Win provided by our own Jr. while he treks the globe in search of his calling. This is an impressively potent rifle but has issues. Those issues have nothing at all to do with performance but instead an issue of safety. In my testing of the re-chambered rifle it consistently lets me know that it has pressure limits somewhat less than published data for the 358 Win cartridge. The rifle always says ENOUGH !!! well short of published max loads for the cartridge. This for me is not at all an inkling of a problem but if some future owner ever decides to use factory ammo in it there could be a problem. I have not tried but 356 ammo may chamber which would be good and a simple re-stamp of the re-stamped caliber designation would be a simple matter to keep it safe. As is basically it uses 356 load data but in the rimless 358 case.
Well that is likely enough of an I hope pleasant distraction from the subject matter of this thread. Its a good example of "" if you cant impress them with facts then dazzle them with BS"""
