Leopold Scope for M1A with Brookfield Mount?
 
I recently picked up an M1A with National Match barrel and sights and a Brookfield Precision Tool mount. I have been trying to decide on a scope to mount on it.

I am looking at the Leopold Mark 4, 3.5-10X40mm LR/T with mil-dot reticle. I would appreciate any experience, advice or caution that any of you can offer.

What about the M1 vs. M3 adjustment knobs? I have read something about the M3 knobs being "mushier" vs. the positive clicks on the M1. Of course the M1 adjustment knobs are 1/4 MOA vs. the 1/2 MOA windage and 1 MOA elevation on the M3 knobs.

Also what about the illuminated vs. non-illuminated reticle?

Thanks,
Cass

Cass, I have researched this a bit and found that for normal
applications the Leupold 3.5x10x40 is the most powerfull
scope you want to have on a 14. The 3x9 is better and the
soon to be released 2.5x8 is even better.

Reticle: An illuminated SPR or TMR is best.

Turrets: 1/2 MOA are best on windage and elevation.

I have a bunch of pictures posted HERE

I am not an expert on scopes - as a matter of fact - I hate variable magnification scopes.
I removed the scope pictured and went back to irons and installed my EOTech on the SEI mount.

Nothing wrong with your selection. Just make sure a competent M14 smith mounts the Brookfield and you will have no problems with that setup. I had the same basic setup but with a McMillan M3A stock. The M3 scope is an excellent piece of glass even with the 1MOA elevation. You can always put it half way between clicks for 1/2MOA changes. If you want to play benchrest shooter get the M1. Otherwise the M3 is good to go. Illuminated vs non is your choice.

Thanks for the replys! Both of you have some nice looking hardware.

Moe, what rings do you have on your rifle and what height are they? It looks real nice. Do you have the mil-dot reticle?

Sunrise, I definitely agree about not going overboard on the magnification. I do want the 30mm tube, but at 10X it can sure waste a lot of time on orientation. I remember years ago shooting jack rabbits at night with my friends .222 with 10X weaver. You could totally lose a jack rabbit in the middle of a hayfield with no cover.

I would think there are very few conditions where the illuminated reticle would help. Is it mostly for reticle contrast in low light?

Thanks,
Cass

I had a Mk4 M1 on my M25 for a while, then got rid of it and put the M3 version on. Tremendous step up, and I wouldn't go back if you paid me to do so, for several reasons.

The mushiness of the elevation knob isn't a factor really. You're dialing to a number. E.G. dial to the middle of the 6, let fly. The windage is crisp on mine.

One of the big differences is you get the 20 MOA internal optical taper with the M3 that you don't get with the M1.

Unless something has changed on the M3LR, it doesn't have the taper either.

Without that, at range, many folks run out of windage adjustment (you're at the bottom of the circle, so there's not much side-to-side play) "out there", where you need the most.

As a proud member of the "I was off by a full revolution on the M1 elevation turret" club, I can tell you that the club is quite large. I know several folks who've done that. You can't do that on an M3.

There are several other reasons as well.........

Cass, the rings are Badger standard height (.823"). The scope has the Premier Reticles Gen2 First Focal Plane mildot reticle conversion.

Thanks, guys. That helps me get started. I shot the rifle with iron sights and it is definitely worth putting a great scope on.

Thanks,
Cass
