Home Forums Hunting & Shooting Hunting Optics Burris Signature Dual Dovetail rings with offset

Looking at a set with the the 20 minute inserts for my 308.

Upsides and downsides?

Looks like a simple, robust solution to mounting a scope to a "tactical" rifle.

A superlative way to correct receiver issues(be it windage or ele),or to pad capability of a glass with modest initial ele ability(Burris comes immediately to mind).

You can stab 40MOA into a system,by going .020" fore and aft,or correct some windage,to yield a mechanical center within a glass to grant optimal erector travel.

I can like the system much,but assuming a concentric receiver,I prefer the LW's...........................

thanks for that.

I'll give it a go

Keep in mind that you can locate the eccentric offset,at any location within the ring.

So you can reap a comb of both windage and ele correction,at the same time.

Slicker than hell and I'd love to see it offered within every ring type,LW's included........................

understood

Just musing aloud,weren't an attempt to slight your savvying the premise...................

An added bonus ; They don't mar the scope tubes, in fact, you can't tell the scope has ever been mounted. A nice feature when switching scopes around on rifles...

That is never a bad thing.

My PosiLign bitch is the teeny fasteners and narrow ring cap surface area.

The LW's in comparison,do much more for me in the warm/fuzzy department.................

Have one of the old original Vari-X II's that had minimal ele. adjustment. It was beat and the adjustments no longer worked when I got it. Sent it off to Leupold. Immediately repaired as per usual, but still not enough ele. once it was workin' emailed leupold about options. They strongly recommended the burris posilign. Went that route and no problems since. They work great. As stick said, I prefer the lightweights, but when it's called for the posiligns are great.

stick,

no offense taken.. thanks for the insight

Optical performance is best in all aspects (abberation, distortion, and light transmission) when the optics are centered. Using the pos-align inserts to keep the optics as close to center as possible improves the performance of the scope, regardless of whether other problems (like limitations in internal adjustments, misaligned bases, etc.) exist.

For example, even a "light magnum" Hornady 270 win load with 130 gr bullets has about 7.8" of drop at 200 yds (from boresight) Add in the mounting height of the scope, and you're looking at about 9.3 inches. That translates to about 5.8 thousandths offset if the rings are 4.5" apart. And that's on top of any adjustments for mounting misalignment to the bore.

You can also use a pair of equal-offset inserts front and back to "dial in" any offset, from zero up to twice the individual offset of the inserts used (i.e. a pair of .020" inserts will give you any amount from 0 to .040").

Recenty Burris changed the design of the signature rings by using two screws per side versus one. I have the old style on two rifles and I think that they are great. With two screws per side the new style should be even better. The 30mm rings also come with the 0 and the .020 offset inserts. If you are using the 1 inch rings you will have to buy the offset inserts seperately.

Just got a pair with .025 offset (0.020 fore, 0.005 aft), can't wait to shoot it!

Thanks, guys!

I think you'll be very pleased. I'm a HUGE fan of the Burris rings w/inserts. Last year I was able to sight in a vx-III 3.5x10 on my abolt 270 without even touching the adjustments on the scope. Granted, it took a bit of time to get the proper match of inserts and to rotate them properly to adjust for windage, but it was dead nuts on @ 200 yards, which is what I wanted.

As others have mentioned, an added bonus of these rings is that they leave no marks on the scope, and I have yet to have a pair slip once I cranked them down.

Exactly....the teeny fasteners and narrow rings make me a bit worried as they needed to be installed on my 300RUM holding down a Conquest.

They did as advertised, won't mar my scope, rifle shoots lights out with about 70 rounds through it with the Burris's onboard, but.........still have that little bit of concern that they could bust loose at any shot. Powerful recoiler, seemingly not so skookum hardware....but the only way I had to turn.

Maybe alot of worry for no reason. New product for me so that's where the hesitation comes in. It was a "have to" situation whereas before I've only used L's DD and T's Steels.

Did they double up the screws on 1" rings, or just 30mm rings?

I believe it is only the 30mm rings that have been upgraded to the two screws per side.
