Home Forums Hunting & Shooting AR and Tactical Rifles Lap the rings on the Aero Precision mount, or not??

So are these things square and straight enough to skip lapping them, or should I go ahead and square em up?

Thanks

I don't think it would hurt anything either way. I usually don't lap one piece mounts. Good ones are usually machined well enough to not need it.

I may just give it a good look with the lapping bar, see if it's fairly concentric. If so, throw it together. If not, or obviously off, put the putty to it.

Agreed........never hurts if it makes you feel better.

You could also buy better mounts, Aero's are OK, but nothing special.

I've had rings and mounts from all price points, and the one thing they pretty much all share, is they aren't 100% true. Some may be a little more consistent than others, but saying buy better mounts is BS. Most all need lapping, regardless of the name stamped on em, IMHO. I realize not everybody laps rings, but I fall in the camp that typically does.

Lapping rings really, really matters (unless the mounts are truly,truly bad) on a gun that's capable of bughole groups & very damn few AR's meet that criteria.

So if it soothes your mind, lap away. Likely your AR will never know the difference.........if you don't think better mounts are more concentric & straight, & you intend to lap them anyway, because they're all bad, then just go buy some Tasco's & lap 'em in.

never lapped a set of AR rings.

But then again I was only aiming for .5 moa accuracy. Best group unlapped ever was 5 at appx 1.25 inches at 600.

Well, hell, Jeff, you prolly coulda wrung another 1/4" outta that 1/2" gun if you woulda lapped the rings...........you left money on the table.

I think lapping rings matters more when mounted on a receiver that is not always true front to back like on a bolt gun. Given a one piece mount, I don't think it would make any difference.

Glad you all have had such positive experiences. Mine hasn't been quite so rosy. But, admittedly, my experience with AR mounts has been limited to only one mount, which was the boat anchor that Burris markets, before I knew better. They were pretty bad, but squared up and worked fine with some elbow grease. It's been consistent as far as returning to zero, or scary close, but the machining isn't great by any means, and it's heavy as all hell. Just cheaply made.

I lap bolt gun rings without fail. But I don't run any one piece systems or any on pic rails. I had a local "smith" mount a scope several years ago while he had the gun to fix a bad base hole. He didn't lap the rings, or even use a bar or anything to align them correctly. Turned out to be a mess. I've mounted all my own since then. And had no issues. Unfortunately we have a serious lack of talent around here, for "smiths".

Hopefully this Aero mount will be pretty good. If not, it'll get the bar and slop put to it. And yes, I am a bit anal about some things. Not all for sure.

Chinese Burris vs. a quality mount...

"Parts is parts" is a lie.

I also don't see the need to lap the Aero mount.

Best group I"ve ever shot with an AR was with a cheap leatherwood scope mount.....it satisfied all my testing for years.

FWIW.

There is no doubt that better built can't hurt. But it isn't always required.

Mounted it up last night. It was pretty true. I didn't bother lapping. Only ding on the Aero mount is that it "twists" the scope a bit when you start tightening the ring screws. Easy enough to allow for though. Not a big deal at all. Overall I'm happy with it for sure. Lightweight, and seems solid enough for most anything I'll throw at it. It's not Larue strong, but not much is. LOL

I just treat the Aero mount like the older Weaver scope mounts that twist the scope when you tighten them up. Like you said, easy enough to account for it.

Depending on the contact points, it may be stronger than LaRue.

I have not lapped the two that I have. Its a pretty good mount. Regards parts is parts, its all in the odds, with cheap stuff your more likely to get an out of spec part.

How many times do we need to see "my gun is not firing, not cycling, not locking back" etc. etc and every time its a very low cost component.

I have not had an AR-15 not work 100% correctly since I bought a Colt SP-1 when they were fairly new on the market, it was an expensive purchase at the time. (Edited to add, one bushmaster that somehow the FSB was misaligned with upper receiver but it worked and one RRA with the gas key not staked but I staked it.)

On the other hand I guess some people who simply just like Fiat's, Chia pet's, ginsue knives, spray on hair thickener, and frontal lobotomies.
