After owning plenty of other centerfire rifles, I built my first AR. I'm a total newb on this platform.

I'd like to mount a low power scope on this build, but I'm not sure the best way. I bought a "standard" upper with no open site. The upper has a giant row of Weaver style rails to mount on. But I don't want to interfere with quick access to the charging handle, yet I don't want to mount higher from the bore and more forward than necessary. I'd guess I'll have 3-4 inches of eye relief with the scope I choose.

I have a Monarch 1-4x20 I might mount. If I don't use that scope I'd get something similar with an objective no larger than 32mm.

Here's the upper I have:

However, my upper does not have the front site shown in the picture.

What do you guys suggest I use for a mounting platform?
 
Both Nikon and Burris make one piece bases designed for an AR-15 as well few others. They put the scope at about the right height off a flat top upper for lining up the eye with the scope.

Low power scopes should cause no interference problems with these bases.

As far as the charging handle, I like and leave the standard latch on mine. You can access it fine from the latch side hooking it with a finger.

There are extended latches available from several manufacturers and I have tried one or two.
 
I researched scope mounts extensively for my AR build and ended up choosing the Burris P.E.P.R. It is available in both quick disconnect and standard mounts. To me it seemed to be the best overall value.

They come with two sets of top rings, with and without the short rail sections.

I have not regretted my choice.
 
you will get a lot of suggestions from the AR crowd, a lot of them rather expensive. I went with a cheap ebay mount that resembles a sleeker and lighter weight PEPR. It has worked well, so they're probably all fine.

Unfortunately, most standard eye relief scopes will put the rear of the scope almost right over the charging handle, and because there is no drop to the stock you have to mount the sight stupid high. (that is why the iron sights are mounted on the carry handle and huge triangle in the front. Anything under 2.5x power and you will probably see your front sight tower in your scope. Attached is a picture off the internet of what appears to be a 1-4x20 scope mounted on an AR similar to yours. Note the high and forward mounting and where the scope ends in relation the the charging handle.

A one-piece AR mount is the way to go. You just have to decide if you need the quick detach version. The thumb screw models cost about half the quick detach versions.
 
RRA cantilever mount attaches/detaches easily and allows plenty of leeway for eye relief...$50

Larue and American Defense make excellent quick detach mounts for your AR. They come in various heights depending on your needs. I would put fold down front and rear iron sights on the rifle and choose the scope mount that will allow the eyepiece to just clear the iron sights when folded down.
 
I have a Burris PEPR and it works great. Holds zero after taking it off then putting it back on, at least close enough. Plus its a good price, I think around 80-90, I also had an american defense one which was around 200. I don't see any difference between the 2
 
Deadnutz makes one of most rugged that I've seen. As noted, the scope will be high due to the design of the rifle. Stronger the mount, the less likely to move. I also have some other brands, don't remember which right now.

Gunfighter charging handle gives a better/easier grip with a scope. Scope with lots of eye relief (as the new Leupold VX series line) helps a lot.
 
I appreciate and looked over all the replies. I'm thinking of getting the Burris PERP. But SWFA makes what looks like a high quality copy for a little less money.

Anyone want to share what they use for a low power scope? Illumination would be nice.

For a sleeper, you might check out the Bushnell Throw Down PCL?
Word is getting around, but everybody that checked mine out has really liked it, and a number of them have ended up with one (or more) of their own.

I tend to go with QD mounts for my scopes - pricey, but I like the convenience / speed. Bobro Engineering mounts seem to be gaining in popularity, and their RTZ performance gets good reviews.

Trijicon must like his design, as they use his mounts on some of their optics, although you may see only Trijicon stamped on the mount.

My SRS came with a QD mount, and you can tell it's a Bobro Engineering unit.

Pay no attention to MSRP...
 
What do you think of the reticle? Looks a little busy.
You can read my review of the Bushnell @ the Amazon link I posted, but to address your specific question:
1. At 1x you won't see the BDC marks - all you'll see is the horseshoe reticle, so it functions pretty much as a red dot scope.
2. When you crank it up to 4X, then the BDC marks are visible.
3. It's a First Focal Plane reticle scope, which ain't easy to find these days without spending big bux - I likes me a FFP reticle scope on my ARs!
4. The red dot is illuminated, but if you lose power / electronics, the reticle is still there, but now in black / gray.

I paid $299 (plus tax) @ Walmart for mine, but back then, nobody but Walmart had 'em.
I had one on order for over a month with SWFA before I gave up and paid Walmart price - you should be able to find them for around $250 delivered these days if you shop around?

I read your review. Good info - thanks. Looks like a good buy. I am going to give it a try and can always sell it at a $40 loss if I don't like it. That's how I justify blind scope purchases - knowing if I buy well a can sell for a small loss.
 
Burris also make a lot of good scopes, the xtr II ones are very nice and the fullfield's. I have a fullfield e1 4.5-14 on my ar and love the floating reticle. Had a leupold vx-r patrol 1-4 with firedot and it was an awesome scope, got rid of it because I wanted longer range. The leupolds are expensive but the burris are a bit more affordable. I like the bushnell elites as well.
 
Aero Precision makes a lightweight & strong mount for a good price. It's normally $85, which is an excellent value, but now it's on sale for $73

Went to a gun show yesterday. I seen the scope(burris ar throw down), I am sold for my M4, best of both worlds. Red dot on 1x, bdc on 4x. ordering today.
 
I have the American Defense detachable with no eye relief in 30mm for a Leupold scope mounted to my WC Recon; very precision both in fit and finish - very, very well built. When I mounted the thing, I could feel the perfect machining of both the mount and the WC - very slight adjustment to the throw arms and just a perfect fit - snug, firm, tight but minus any gorilla torque - very, very nice mount.
 
(burris ar throw down)...
That's Bushnell, not Burris (assuming you're talking about the Throwdown PCL?).

I have to catch myself as well when talking Burris / Bushnell - EZ to mix up the brands when the mind is running ahead of ye olde fingers... :eek:

I've got that same Bushnell scope, mounted mine with a Weaver 30mm SPC mount. I had a a Trijicon TriPower before, and the Bushnell offered everything I was looking for in a scope. I've got a carbine length gas system and my front sight disappears before I get to 2x. At 1x, the reticle is just above my front sight.

It is nice, ain't it? Got a feeling a lot of folks automatically dismiss it because it's a Bushnell, but I ain't no namedroppin' elitist. :rolleyes:

At's OK - leaves more of 'em fer us working class stiffs and those that prize performance over name.

My only question about it now is how tough it is and how long it will last, but we won't know that until they've been out a while and enough folks have put them through the wringer.
