1 vs. 2 Piece mount for AR

[.375]

Is there a benefit to using a one piece scope mount on an AR?

Easier quick detach I suppose.

What's your general use of the rifle?

If it's a heavier caliber is say 2 seperate rings from badger or similar. Do you run BUIS?

If you have a plinker/comp gun with a 1x4 then a qd one peice is what I'd run.

Most of the one piece mounts solve the problem of not having enough receiver space to fit two rings on a normal profile scope.

You don't want to mount one ring on the receiver and one on the railed handguard, unless you have a monolithic receiver.

A 1 piece also let's you cantilever the scope farther forward. Depending on your scope and shooting style this is needed on an AR.

For 1 piece you also get the rings machined together so there's no need to lap the rings since they are much more likely to already be aligned.

This summer I broke down and bought a Night force. I also purchased a Bobro quick release one piece mount. What a smart move. If I'm working on my Ar, or cleaning it, I pop the scope off and leave it in the safe. Decide I wand a 3x9 instead of a 5.5x20, bam! Done. It sucks coughing up the cash, but no regreats.

thanks, that helps

One advantage of a one piece is they're available with 20 MOA cant for long range. I went with the Nikon 20 MOA mount for my 308 AR it's a good mount but far from a quick detach

Lapping rings is not done for alignment. Alignment is done with these:

I see the Nikons and the pepr model - are there lighter weight models?

The Nikon AR223 mount is 5.1oz, the Larue mount is 7.1oz vs the Burris P.E.P.R 8.7oz

I have been using the Millet 1 piece mount. It allows me to use the Caldwell pic rail mounted brass catcher when I have the scope on my ar. I remove and reinstall the scope often with no drama. I have a red dot that gets about half of the action.

FYI, Wally World had the Millet 1 piece mount on closeout for $30.00 recently. I think I spent $60.00 on mine.

The Cowboys just lost an onside kick by Da Bears. They are trying to lose, but I think they will win anyway.

At least Nikon makes a two piece mount, the P-223 if I remember, that is cantilevered like the one piece mounts. The advantage to them it allows for a bit more flexibility in ring placement on the rifle.

On a number of my ARs, I use a picatinny rail mounted brass catcher and the two piece mount gave me some better options on placement of the brass catcher mount.

The one piece mounts would be more rigid.

Aero Precision is super light. 3.27 ounces ain't bad.

I like the fact that the rings on my DNZ Freedom Reaper ring/mount combo are aligned, and they have never left a mark on my scopes - I'm on my seventh DNZ mount, three are on ARs. I've been told that the first CNC pass cuts the ring centers, can't be misaligned with the resulting torque on a riflescope.

Bonus that they are made in the US of A by 'Mericans in North Carolina. Go Tar Heels!
