Thinking of getting a Vortex Crossfire II 2-7x32 scope for my M&P 15. Trying to keep scope cost around $150. Is this a decent scope? What mount and rings would I need? Will the front post sight obstruct scope view?

EXCELLENT scope, I have it on my old Marlin 60, my FAVORITE 22. I have the Diamondback 2x7x32 on my old Ruger 10/22, prefer the cheaper in price Crossfire, more eye relief. I just put a brand new Diamondback 4x12x40 on my Mini14, at only 12" long, keeps the rifle compact/handy.

342ti Thanks For The Info.

Look around for Nikon P223.
Love mine. excellent ballistic reticle.

The front post may obstruct the view when the scope is set to the lower magnification levels. It will ghost out and not be visible at 4x and above.

I have a Leupold 3-9X40 on mine and the front sight isn't visible at all on 3x.

This will depend on where the scope is set on the rifle and the scope itself. Some people can't see it on 3x, and some can. 4x and up is typically good to go.

I guess I wasn't clear.... It will depend on where and how the scope is set up based on the eye relief needed for the shooter.

In the pic above, the scope is mounted too far back for my preference. I was taught to shoot nose to charging handle in the military, so I would need the scope to move forward. With it mounted like above, there is no space to move the scope forward. I wouldn't want the scope interfering with access to the charging handle either. I want that charging handle to be readily available for grabbing from any angle. I also would not want my rings up against the turret housing... prefer for the scope to be more centered in the mount.

For mounting the scope properly, I recommend a one piece cantilever mount like the Burris PEPR. This allows you to move the scope forward for proper eye relief vs. moving the stock out to change your shooting position and how you mount the rifle. It also moves the ring out past the end of the receiver, allowing for better centering of the scope in the rings.

I have the eye relief that I like. When I shoulder the rifle I have a full field of view without changing the position of my head. It doesn't interfere with the charging handle.

Glad you are happy with that setup. It isn't the way I would choose to do it for reasons listed.

I can address the Crossfire and rings but don’t have any experience either the M&P15.

Last year I bought a Ruger precision 22 wmr and mounted a Crossfire 4x12 with AO using Weaver rings. Let me just say I’m very impressed with this scope and wish I’d bought another to put on a Thompson Center Barracuda 22. I read a lot about Athlon scopes and bought a 3x12. Both scopes have very clear optics but the Athlon has purple color fringing at 12x where as the Vortex has none. I’d say the Vortex is better built too.

The Weaver rings are excellent. I can’t tell you the model but it has a built in level. They were very well made and finished. Price wise they were around $55. No complaints.

Hello everyone I just joined this for and I recently inherited a. M&p15 sport 2 from my mom and it has never had a shell ran through. I put a bug buster scope on it but have not sighted it in yet due to I do not know if I need taller mounts. I know at low magnification you can see the front iron sight and at high magnification you do not. But I also had to remove the rear sight to mount the scope. Any info would be great. By the way this is my first ar.

I recommend going with the one piece cantilever mounts designed for the AR for this reason as well... proper height without a lot of work!

Most will want the scope mounted with the center the same height (or close to) as the center of the rear sight. For that, you would want the center of the scope to be close to 1.4" up from the rail. 1.375" to 1.5" is where most AR specific rings and mounts will get the scope. You may have to go a little higher, depending upon the scope and the size of the objective bell housing. If you go much lower, most will find that it is difficult for them to get their face low enough on the stock to get a comfortable cheek weld and be able to see through the center of the scope.
