Just picked up my first 15

[storeyteller]

OR's are, by name, ready for OPTICS. Personally, I would take the $200+ the flip up sights cost, add that to my optic budget, and get something 'really nice'. But that's just me, do what YOU want. I have a sport and have basically made it into an OR (no BUIS) with various other upgrades, accessories, doo-dads, thing-a-ma-jiggers and some downright junk.

Pick out something (specific) that moves you, ask what others experience is and where is the best place to get it. There is someone on here that has been there, done that, and is a tight-wad to boot.

Good luck, be safe and happy hunting.

Yep, I would skip the BUIS myself, I have two AR's actually made from one Sport plus some extra parts and dont have irons on either. one wears a 6-24x50 Bushnell and one wears a Bushnell Banner 3-9x40, both 16 inch barrels. I changed out the gas block on the Sport and put a rifle length free float handguard on it and am getting ready to do the same thing to the other. Bipods and good to go. Plus didnt spend a heck of a lot of money on either, always looking for good deals.
Good Luck

I have pretty much decided to bypass the BUIS simply because I am right handed but left eye dominant. For now I have picked up a sightmark red dot sight. Just to get used to one. I will pick up a better one at a later date. For now that is all I have done to it. I am thinking of a low profile gas block and a longer quad rail. Definitely want a bi-pod and may not put anything else on the rail. I want the rail because I like the way the rifle looks with one on it. If I get a low profile gas block, is it a simple remove and replace or do I need to do anything special to get it mounted?

 

[storeyteller]

If you can change the oil in your car then you can change the gas block (and do other mods as well) yourself. There are videos on youtube that will be very helpful. You will want to get an action vise and an AR multi-tool.

I would never put a sight on the hand guard because it (the hand guard) flexes when you grasp it. The sight belongs on the barrel, and the closer it is to the muzzle, the better. Both of my ARs use a gas block with a flip-up sight.

Well excuse me!

I agree, in a perfect set up.

The OR is a optics ready gun, so BUS are usually not a big priority.

I was just suggesting an option, not trying to build the ultimate battle rifle.

I'm glad your ARs are perfect.

There are a lot of AR owners who use up to rifle length hand rails with BUS mounted on the rail, I guess they are all wrong.

Why are you upset? I'm merely giving the best advice I can.

I was merely pointing out that putting a sight on a hand guard is not optimal, and gave a reason for it, and it even applies to sporter rifles. Yes, putting your front sight on the hand guard is an option, No, it's not the best option. Will it actually make a difference where the sight is mounted? It really depends on the shooter and his hold on the rifle, and more importantly, whether or not he's using a sling for support.

When I built my frankenrifle, I built it for the best possible accuracy and most reliable operation. This means using a free-float hand guard with the front sight mounted on the barrel, and the front sling attachment point on the hand guard.That's the entire purpose of using a free-float hand guard - to remove the stress from the barrel. If you mount the sight on a floating hand guard, the sight points where the hand guard points - NOT where the barrel points.

your ARs are perfect.

If only that were true...

My S&W still doesn't have a floating hand guard (just haven't gotten around to replacing the MOE part), and the triggers on both still need some work.

Regarding operation, though, I've never had a failure of any kind, and I even shoot the evil steel-cased ammo (Tula 62gr), but that might just be because my rifles have dust covers and forward assists.

Stupid question number 437.389

I always clean my new pistols after I buy them but before I shoot them. Good habit to stay in with the 15? I can only assume so.

Clean ANY firearm you buy before shooting it.

Another stupid question...why a magnifier?

 

[S&WOkie]

I can see why some would want to use a magnifier, but I don't like the disadvantages of using one.

They cause you to lose the unlimited eye relief of the red-dot, and it creates a narrow field of view.

With my old eyes and a 1X red-dot, I am able to do real well out to 400 yards, so I don't see the need for one.

If I wanted to shoot much farther than that I would just use a regular scope.

 

[TangoFoxtrot]

Congrats on the new rifle. I buy from MidwayUSA, fast accurate shipping.

What is a buffer and what is an h-buffer? I am assuming that an h-buffer is similar to an h-pipe on an exhaust system in that it equalizes pressure. How correct would that be? Which one does my OR have and would it help anything to change it?

 

[oneyeopn]

a buffer is the round piece of metal with the poly end that fits in the spring of the buttstock of an AR or M16. In the old days you had rifle (fixed stock) buffers which were longer than the Carbine buffers (collapsible stock) Now with all the variations in gas tube length and hole sizes you can get buffers of different weights to make your rifle cycle slower and smoother or faster and harder on the rifle. As was said in another post and I dont remember the weights but you have a buffer then an H(heavy) buffer, then and H2(even heavier) buffer and so on. Right now I do not remember the different weights or what would be in your rifle but you can put in a heavier buffer but weigh yours first to make sure you go in the right direction, it will slow down the cycle speed but also soften up the action.

 

[Rumur]

That's good to know. I had no idea that the H stood for heavy. Just makes sense. At least more sense than my exhaust theory. LOL!

Eotech, Aimpoint , Trijicon , maybe a Leupold Hamr don't waste your money on anything else buy once cry once

Another stupid question...why a magnifier?

A magnifier effectively turns your 1x red dot scope into a magnified optic (like a regular rifle scope. Instead of getting a red dot and a magnifier, get a scope that is adjustable from 1x to 4. It will be less expensive overall than buying a quality red dot and a separate quality magnifier. There are several reasonable quality/price 1-4x optics available. The only downside of this is that the 1-4x optics are heavier than just a red dot.

Took my 15 out for a test drive today. I LOVE THAT RIFLE! Ran 100 rounds of Remington 55 grain green box through it with 0 issues.
