I just got one of the new Trijicon 1-8x scopes for my .223 SPR, and I'm thinking about going with some nice rings instead of a one piece mount, hoping to save some weight. The rifle's already on the heavier side, and the scope is adding another two pounds to it.

The rifle has a monolithic upper on it, so that's probably a consideration. I also do not need or want a QD mount, as I don't plan on removing the scope once it's mounted. I also realize I will need to lap the rings, and I'm perfectly willing to do that. So the question is, am I giving up any accuracy potential going from a one piece mount to rings?

And if so, will that make one lick of real world difference for a .223 with an 8x Trijicon on top?
 
As long as its properly installed (and of quality construction) it won't matter, For a 1 piece setup, check out the Larue SPR mount, For rings, the Larue 123 rings.

Those are all QD aren't they?
 
I was thinking about going with these: https://ads.midwayusa.com/product/173014/leupold-mark-4-picatinny-style-rings-matte?cm_mmc=pf_ci_google-_-Optics - Scope Rings, Bases, Mounting & Accessories-_-Leupold-_-173014&gclid=Cj0KEQjw2fLGBRDopP-vg7PLgvsBEiQAUOnIXHbNSPAU9I2G0brl80KLGspqtn0zJd2AT73lOmpl0-QaAvY_8P8HAQ

The 34mm ones are on sale with free shipping!:)

I wish they were a little wider, though. That's one thing I really like about the Spuhr rings is that they spread the force out over a wider area, but Spuhr only makes low mount rings, so I would need a riser, in which case I might as well just use a one piece mount and be back where I started. It's frustrating...
 
Yes, I believe ALL Larue rings and mounts are QD. Also, the tension is adjustable- not all rails/bases are created equal.

I'm probably going to go with just the standard screws, whether it's a mount or rings. I don't need QD, and it's heavier and more expensive so I just don't see the point.
 
As ridiculous as it sounds, I may just go with a Spuhr 1 piece mount. To get a set of quality rings and the lapping tools would put me in the ballpark price wise, and still not be as solid. The Spuhr mount also has a cantilever and still has four cross bolts on the base, so it's a more solid setup than rings and will keep everything mounted to the receiver (even though it's monolithic, I'm sure the rail still has more flex than the receiver portion). It's slightly heavier, but I've learned in the past few days that six screw rings aren't exactly light to begin with, so I think the weight difference will be largely unnoticeable.

It's either that or a simple pair of Leupold rings. The Leupold rings would definitely save me some weight. But I do like the idea of having more surface area touching the scope on the Spuhr mount. Above all, I don't want to leave marks on the tube. I know it's not a S&B, but it still wasn't cheap and I'd be pretty bummed to take it off in x number of years and find a booger on it.

Decisions, decisions...
 
Looked at the Trijon web page because I didn't know anything about this scope. They have the scope mounted with two rings. My guess is the none standard tube size limits the choices. I'd give Trijon a call and see what they use. I'm betting you won't have to lap anything if your upper is machined correctly..

Trijicon has their own line of rings, so I'm sure that's what they would suggest. They're about the same price as the Leupold and appear to be more or less the same thing. Neither set though claims to be matched or made to any degree of precision, so I'm assuming lapping is probably indicated. In any case, I don't trust the upper to be 100% flat. The handguard is actually a separate piece from the upper receiver and is then welded on. The result is a monolithic upper, but the continuous top rail isn't machined in one piece like the LMT ones.

Note that the scope body itself is 34mm, so pretty much everyone makes mounts and rings that will fit it.
 
Aero Precision makes a mount that fits 34MM. I did a quick google. Surprised at the amount of choices.
My Aero works fine on my Aero upper with a Vortec 1x6. Have shot several run and gun type matches and its holds zero.
I mounted it once with loctite and its a none issue. Scope lapping is a fairly recent service. IMHO its a service that only rarely is needed.

I had a scope get boogered by unlapped rings. Wasn't an expensive scope, but I will never put a scope into unlapped individual rings again without checking for alignment first.
 
I went with the Spuhr 4026. By the time I got a set of six screw rings and the lapping supplies I was looking at the cost of the Spuhr mount and not much in the way of weight savings. The way the scope is set up with the erector assembly so far forward, the front ring also would have been way out on the rail, and there is still some flex in the rail itself. I think the Spuhr mount was just an overall better solution for me than rings.
