RE: Marbles Bullseye Sights

Awhile back I picked up a CBC R92 SS 16" 357MAG, great carbine, nice wood, great trigger, butter smooth action, but I'd like to replace the buckhorn sight. I like the Marbles Bullseye sight but I've heard they tend to shoot high, especially on the 16" bbl. If that is the case, one should be able to remedy it with the right front sight height.

Anyone have the Bullseye sights on their R92? If so, what is your experience with them in regards to shooting high?

I tried one, very nice sight, same carbine also. I just couldn't get it to work with any front sight. To make problems worse, the dovetail cut for the front sight was so oversized that no front sights would fit. The factory Rossi front sight just fell off somewheres. I got tired of trying different sights and wrapping tape on the dovetails to get them to fit so I bought a Skinner
Picatinny rail made for the Rossi 92 and a Sig Sauer Romeo 5 red dot and called it good.

Jack,

Have you looked at Steve's Gunz? He bills himself as a Rossi 92 specialist. When I was shooting Cowboy, I found the sights I needed for my R92 there. I ended up with a full buckhorn rear and a large ivory bead on the front. The buckhorn served almost like an aperture. And you're right, that action is like butter. I've never seen a smoother action on any lever, even my Win 1866 (copy).

If there's nothing in his products that looks like it would work, you might try sending him a message.

In any event, mechanical sights are all about geometry. Once a rear aperture is mounted, it's a matter of raising or lowering the front sight until the point of impact is where it needs to be.

You can use a pinched loop of electrical tape as a temporary front sight for testing purposes. Clip the top of it to raise the POI, make it higher to lower POI, etc. This will give a ballpark idea of the necessary height for the front to order or modify.

The above is suggested at the risk of telling you what you already know.

Jack, been to Steve;s sight many times, order some parts from him.

I like the Bullseye sight, just heard they tend to shoot high, even with the fiber optic front sight Steve sells for the R92. I think I'll have a chat with Marbles to get the right front sight height.

Also looking at the X-sight peep sight, but I need to D&T the receiver for it. I thought about the set up you have, just need to make up my mind. LOL

I love this R92!

Thanks

I have 2 rossi's 45 colt and 357 both 16" barrels . I put williams fiber optic sights on both red front and green on the rear I got the sights from midway usa rear part # 354276 and front part#517699. The rear comes with a front but is to short. I tried the williams bullseye but didn't care for it. My eyes can pick up the red and green fiber optic sights really fast and work great for woods hunting

I've had several chats with Steve, he sells what is listed on his site, has no other recommendations, regarding the Bullseye sights. Other than admitting, he's heard the tendacy to shoot high on 16'bbl R92.

I plan on calling Marbles directly and asking them what gives. Otherwise, I might just go with the X-Sights. Don't really want to go with a red dot on this carbine.

Good to know, John. Can you provide the particulars of what peen you used? I don't want to damage the X-sight.

I know this is an old thread. I have 8 lever action rifles with the Bullseye sight on them. It is my favorite sight. To get the rear sight low enough to hit point of aim is a struggle if not impossible with the Bullseye sight. I always replace the front sight, I usually end up putting a .5 front sight on most. Gives me the adjustability I want. Here is my 18" Big loop Rossi in 357 Mag with that front and rear sight combo on it.

Is the 18" BL a new model? I don't recall seeing one available before I bought my 16" SS 357MAG.

Regarding the front sight, did the .5 front sight require any dove tail work or does it fit the factory dove tail? That seems a tad tall but not much one can do to lower the rear bulls eye. Wish there was.

No, it is a 16" barrel. Brain Fart moment. As far as the front sight, it fit the dovetail pretty good. If any work was done it would have been filing the front sight it's self. I have out so many of these sights on front and the Bullseye sight that I forget exactly how they went. But have only had to file the sight it's self. Ordered three more bullseye sights yesterday.

Appreciate the response as I can now stop scratching my noggin. LOL
Is the .5 front sight the shortest one can go for the Bullseye sight to make it work well? I really like the Bullseye sight and wondering whether a front sight measuring .425 or .45 would work, if available.

Jack

Probably depends on the rifle's barrel length. I would imagine the .45 is fine. I have a 20" Winchester I putting a .45 on today because the .5 has the Bullseye sight ramp second from it's highest setting. I want to bring the ramp down a little.

I have two R92's, a 16" and 20". I'd like a fiber optic and question whether Marbles has them in .45. Might need to call them.
