Here it is with a Rock River 1 piece scope mount and Leupold AR 3-9x40mm

I also got some screw in apertures from Bushmaster, which are threaded the same.

Rock River has two hooded choices, the .030" that came with mine and is too small for me to see well out of, and a .040". With either of those, you can't use the 2nd larger aperture that is there and would flip up but is blocked by the match hood.

The hooded aperture screws out, and can be replaced by a RR different size, or a Busmaster. The nice thing (for my purpose) about the Bushmaster ones is they come in either hooded or flush like a button. With the flush one screwed into the threaded aperture hole, you can also flip up and use the second much larger stock aperture that comes with the RR national match sight. I ordered a .040 and .052 and liked the .052 so have that currently screwed into my carry handle sight. I don't know what the large hole aperture is, but I'm guessing something like .125 or maybe .200

Anyone know what size the apertures typically are on an M-16?

You are a more dedicated shooter than I am. I got an A2 upper receiver with a NM rear sight and an A1 upper receiver with an A1 aperture and I replaced them both with A2 apertures. I couldn't allow myself to "try something new." They were just too small for my comfort.

When I was in the Marine Corps I put four dots on the rear site to act as a reference point for aligning the front site post. Now a days Troy makes a rear site with the same idea. I suppose it hind sight it is not possible to have placed those four dots exactly correct without cant.
But I qualed Expert all three times I went. And Only missed twice from 500 yards (both in boot camp) My problem came at the 200 standing a few times as the front site transitioned off target I couldn't keep the trigger pressed and held at the same spot and I would flinch or something and send a not so well aim shot exactly 6 inches low.

Trigger control on the Ancient M-16 A2's was a difficult proposition at best. Seems like the weapons I was issued had trigger made out of sand paper. I got out in '07 and I understand the new A4's have much better triggers.

Back then they taught us to center the front site on the target but I always used the lolipop method anyways. Hard to focus on a black front site against a black target.

Thanks, that's good info.

I like the white dot idea, too.

Great information on the military sights.

.070 = small
.200 = large

ithaca_deerslayer · 11-19-2012, 16:01

Getting better with it, got a couple groups under an inch.

Next time I bench it I'll sandbag it front and back. Here's some targets just resting the front. Feel like I'm not holding steady enough and still moving the scope around too much.

ithaca_deerslayer · 11-20-2012, 12:35

Did some more shooting today with the Black Hills match HP 77 gr. At 100 yards put 5 into a nice 7/8" group, same low point of aim as yesterday's group.

Then raised it up to get on target and establish my zero for this load. My crappy shooting opened the group up to 1.25", but it is now on target

Next, shot a group at 200 yards, keeping my established 100 yard zero. Bullet doesn't drop much. With practice I'll play with keeping the 100 yard zero as baseline, and learning how many clicks to go up for each distance.

I want to get some more of this ammo. Not sure if it is what my gun likes best, but 7/8" groups aren't too bad so far for my lack of shooting skills

ithaca_deerslayer · 12-09-2012, 17:25

Shot my best group ever. 1/2" from 100 yards. Decided to try 52gr match hp from Black Hills. This is my first group. High because I was zeroed for 77 grain. I've never shot a group this small before with any rifle. The dime actually covers all the holes

After zeroing and shooting a total of 5 groups at this distance the average size was .975". I'm sure I'm the weak link, but my gun does seem to like this ammo just a little better than the 77gr which averages around 1.125". Again, this is with me as the shooter. You could do better

ithaca_deerslayer · 12-09-2012, 17:36

Also shot 1 group of 52gr at 200 yards, after zeroing at 100 yards. At 1 7/8", this probably the best 200 yard group I've ever shot. Doesn't drop much at this distance. I've got to get more of this ammo and see if the right drift is me or if I can tighten it more toward the center

Rooster Rugburn · 12-09-2012, 19:35

I_D, that's mean. That's just mean man. The brand whores are going to soil their undies.

IMO, that's good accuracy. Of course with a Noveske or Colt, you can shoot east, the bullet will circumnavigate the globe and come out of the west and hit the target in the same hole, but that's not bad for a 27th tier rifle.

I wonder if a stronger scope would tighten them up? I have a Leupold scope that size, and the size of the crosshairs are bigger than the target. Not extremely precise at those ranges.

***faawrenchbndr*** · 12-09-2012, 19:45

Make some targets.......black card stock with white 10" centers

Do you purposely say the words "brand whores" and "fanboys" in every thread just to be an ass, or are you ignorant to the fact that you spew nonsense all the time?

STFU!!! It's an industry term.

bigmoney890 · 12-09-2012, 21:11

So you're in the "industry" are you?

Funniest post I've read this week.

Yeah a higher power scope would help. Also could use a good rest. I just sit it at a bench and lay down some boards with a bag of kitty litter on top of that. Thought about buying a lead sled, but figure resting on something, like a fence post is how I'd do most of my real world precision shooting.

As for the scope, higher power costs twice as much and I didn't want my wife to yell at me

Plus, I've really got to get the scope off soon once I know the ammo, accuracy, and trajectory, so I can put the carry handle back on and work on learning to shoot irons. Well, that's one of my goals

As to brand, I've got nothing against Colt. They just don't make this setup. This Rock River has been running fine. No jams, no problems, and seems easy to clean and work with. I'm real pleased with it.

I like Colt and BCM too. But if you remember, when you first mentioned this rifle, the brand whores chimed in with the typical, 'save up and buy ...' bull****. Logical adults chimed in that it would be all the rifle you need...... etc. And it is.

Now look at you, shooting it, getting good groups and loving it. What does that tell you? Just like the rational people predicted, it is all the rifle you need. And guess what. If you had spent more on a Noveske or whatever the brand whore favorite is this week, you wouldn't be getting any better groups.

Now you are having fun, posting targets, and the brand whores are sulking. They were wrong again, but they should be used to it by now.

I'm glad it worked out well for you, and you are happy with your purchase.

bmoore · 12-09-2012, 22:19

OP- Glad you are enjoying your rifle. A 20" AR is a joy to shoot.

Most "brand whore's" are not very concerned about groups. Your a tad clueless.

Us brand whores are concerned about reliability in a range of conditions.

Need just a little more light through the peep. Even then, so hard to be precise putting that front post on the target. I'm so spoiled by having 9x magnification, or better.

This is a real challenge, a whole new ball game in shooting.

Note that it won't be till I get a scope that I'll any chance of ever getting sub MOA shooting from this gun

Now you can understand whats going to happen if your optics ever break or a battery dies.....BUIS
