The only thing worse than the dorks in this video are the sycophants that think they're cool.

+Ralph Edwards indeed we dont! you not only have us watchers @Military.com

No. Do this. BZO at 36 yards for a 300 yard sitting. adjust rear sight up 3 clicks even if ur using a Kac rear sight or Ma tech (USMC desined the A2 Rear sight back in the 80's A2 rear sight is a BDC. ONE click of adjustment is an adjustment of 100 yards. USMC uses yards not Meters as the Army does . take 3 mags. 2 mags with 3 rounds each, 1 mag with 4 rounds. shoot ur frist 3 rnds check ur target. adjust front sight ONLY for up or down leave ur rear at 3 clicks up. make changes to wind left or right. repeat 2 more times. u should be in black by now. if your target is from o to 99 yards bring the rear down 3 clicks. 100 yards, 1 click up from 8/3 or 6/3. 200 yards 2 clicks up. 300 yards 3 clicks up. make sense now? USMC adjust rear sights to 8/3-3, for a flat top A4 or M4 6/3-3 from the factory settings. by doing this at 500 yards we adjust rear to the 5. so if u have not adjusted rear sight from 8/3 put ur rear on 8 for 500 yards. Marines unlike the Army, we shot at the 200, 300 and 500 yards, i did it with an A2 made expert every time. this how marines been doing it since the mid 80's. this 25 metter, one click up crap is the Army way.

Did you mean locking the slide back on a pistol? Whe. They say platform, they are referring to the AR15 platform, but it doesn't have a slide. Its a rifle. A pistol has a slide.

Thank you

The large aperture (usually marked 0-200) is for close (and moving) targets and low light as you stated. Generally, you would use the smaller aperture overall. There is a verticle offset between the two as well with the A2. No offset IIRC on the M16A1. We used the 0-200 when doing night fire qualifications and with the M17 Protective Mask back in my Army days. (M16A1 and M16A2 years. Remember too that the sight-in shown here is with a 20-inch barrelled A2 type following military procedure. Both the sights and sight-in system are for use with M855 ammo. The green-tip 62 Grain stuff. For anything else, be it carbine length barrel and/or different ammo, you will need to sight in and then check where your points of impact (POI) end up at the different ranges. I'm sure that only clarified one thing and tossed mud on everything else. Generally speaking though, you will use the small aperture unless you absolutely need the extra light to pass through of the larger. Smaller apertures are more precise as long as you have the light to see with them. My personal AR is a mock Dissipator. It is a 16" barrel with a mid-length gas system, but with the front sight mounted at the same spot that you would find on a full 20" barrel and using full-length handguards. For house and close ranges I run a carry handle with the 0-200 flipped up and a good light on it. I can flip the light on and have a good sight picture fast that will put rounds on target at those ranges. I also have it sighted in for 50 yards with the large aperture because that's how I would likely use it. However, I've changed its role a little so I'll be resighting using the military standard sight-in to start with the ammo I'm using then verify POI at various ranges. Depends on what you want to do with the rifle/carbine.

@@WolfQuantumThis was a very detailed comment and I appreciate that you were willing to share. It brings me great joy to see others point out some details that most either don’t know about or skip over based on training time available. Particularly the part about confirming your zero at distance. The Army has actually added this as a mandatory practice in the newest annual individual weapons qualification. As part of Table IV in TC 3-20.40, after grouping and zeroing each soldier must confirm at distance with the standard being, after completion of the 25 meter zero, the Soldier must successfully hit a properly presented E-type target with a minimum of four of five (80-percent) shots at multiple distances beyond the normal 25 meter line.

With these types of sights, you want the front post in the center of the peephole on the rear sight, but with sights like the kind on most handguns, you would want the top of the front sight post, to be level with the top edges of the rear sights.

@@John_Doe_6996 there's no top edge of a rear sight on an AR15. The rear is a circle.

@@andrewjohnson6907 read my comment again, I referred to two separate types of sights.

@@John_Doe_6996you comment regarding sight picture was on point but did not answer the original question. They were asking about point of aim. And it would be center of mass or as they put it, cutting the target in half.

Yes

The upper for the m16a1 is a fixed carry handle, the A4 is a detachable carry handle. They also have different front sights. The A4 has a F marked front sight designating "flat top receiver" (or detachable carry handle).

I'm confused on your first question, are you asking if you could use a m16a1 upper and barrel with a m16a4 lower? The answer is yes. Or if you mean a barrel from an A4 with an A1 upper then also yes but it would need a non F marked front sight

Typically yes

mark the sight with a paint pen then go back and rezero it in with a different grain and mark that with paint pen as well. so when your shootin different grains you can just go back and move the sight to where it needs to be

Yes, and so does the barrel length. The rear sight elevation knob on the M16A2 and on the detachable carry handle of the M16A4 are calibrated for M855 62gr green tip. If you had the average AR15 with a 16 inch barrel shooting M193 55gr ammo, you may want to use a 50/200 yard zero

Late reply I know, but I hope you see this. Please do not have anyone do this task for you. I cannot stress this enough. There is enough open source information out there for you learn this task. If you are going to pay for anything at all (and I really hope you don’t) pay someone to TEACH you how to do it. Not everyone holds a fork or a spoon the same way. If you get someone else to hold the spoon, you might end up with food everywhere but where you want it. Please look into this. The way you hold the rifle, the amount of pressure you have on the stick in your shoulder, the tilt of your head aiming down sights, the distance of your eye from the rear aperture, or even the way you squeeze the trigger will alter things. Long story short, if you have someone else zero your weapon, then it will be zeroed to them and not you. You might be close or “on paper”. But this is a basic fundamentals of marksmanship. You want it to be done right? Seek the knowledge, apply it, learn and grow.

@@YumYumGetSum no worries about the timing, I agree with you. I never ended up paying anyone. I did ask a buddy former service member for help and was able to learn a few new tips and get the rifle zeroed. Still learning and practicing. One thing he had me do was tape earplugs to the stock so my cheek well and head tilt didn't change. The idea is that when one ear plug is in the corner of my mouth and the other touching the front of my upper cheek I would know my positioning was proper and could easily replicate my position until it becomes a natural hold. Idk if that makes sense but it helped. The other thing he informed me of was my handguard needed a riser for the front sight which in combination with the other tip he gave me, dramatically changed the zeroing process. I was almost immediately able to zero and in the process learned alot.

If it has a Z to the RT of the 6/3 then turn clockwise to the Z to BZO the weapon, after the BZO put it back on 6/3. Then kill the enemy.

It only means that the 8/3 is a 20 inch barrel and the 6/3 is a shorter barrel still 600/300 or 800/300

6/3 is for flat tops M-16A4 20in bbl and M4 14in bbl, both come with DCH from the factory with 6/3. Even if wanted to put a DCH on a 10.3in bbl it will still work for BZO. BZO at 36 yards for a 300 yard sitting. adjust rear sight up 3 clicks even if ur using a Kac rear sight or Ma tech (USMC desined the A2 Rear sight back in the 80's A2 rear sight is a BDC.

​@@candavreedNo. for any flattop. 6/3 dch is for both the M-16A4 20in bbl and M4 14in bbl. both come from the factory with a dch in 6/3. you ever seen a dch in 8/3 for a 20in bbl? if been in th Marines in 2004 when we switched over to the A4. all the A4 came from FN with dch with 6/3. when u have a flatop with dch on, the dch sits higher then an A2 rear sights. even in the USMC M-16A4 manual explains this.

good praactice,

While in between eating crayons

The video isn't a how to shoot. Its how to sight in this rifle. You're overthinking and requesting a video of their choosing become something it wasn't meant to be. If I do a video on how to change the oil in my truck, Im not going to include how to drive the truck and study for written test for a license.

@@sjeverett75zeroing is part of learning how to shoot.

You'll need a vice to hold the rifle while you bore sight the iron sights. If you're truly in the field of just don't have a vice, it's way faster to just shoot it and make adjustments.

@@sjeverett75 Of course I use a gun vice But sandbags would work as well

No that's the distance for a junior high..... A high school is more like 36 meters... You know, the same distance between you and your mind.

Ayo wtf

What.

nigga what the fuck you talking about

please but the rifle and run away

Lol they finally read this comment and they did xdd
