While in the Corps I carried and qualified Expert with the M14 during basic then again for the next three years. Your sights are calibrated for use with M80 Ball ammunition so use that exclusively if you want/need your sight adjustments to be accurate at differing ranges. Your forend support should be positioned just ahead of your magazine. You have it under the gas block where it is adversely affecting the barrel. FYI: the Marine Corps range for Battle Sights was 300 yards...yards, mind you. We zeroed our rifle to that distance and never touched the sights after that. Regardless of the enemy's range, we aimed for the "belt buckle". If he was very close to us or 300 yards away, that's where he got hit. Anywhere else in between the impact would occur anywhere from the beltline to 13" above, a kill shot guaranted.

Not bad considering that I qualified with both the M1 and M14 in my career. But zero windage is adjusted with the rear sight in the middle notch and the front sight is slide for windage. But that was starting in 1961. Vietnam 1967-1972: M14/M16A1 and then a great M21. Still shooting long range at 80! Stay safe out there, bad times coming!

That's what I was taught. Windage is done with the front sight and I'm 71

@Mac-mu9cs 4 месяца назад

You might have had better results with more consistent front rest placement. The front rest was all over and on the gas system. Go prone and use the sling and a sand bag for support. Also use a smaller bulls eye. At 25 yards a 2” aiming black would be a bit better if your using a center hold. Your windage should be adjusted with front sight drift. Now that you have your zero , time to calibrate that elevation drum.

This brings back memories. Fort Ord, days spent on the beach ranges. Running back and forth to the seaside ranges. I had some training on the Garand before basic but the training I received brought me up to hitting 600M man sized targets at about 90%.

@cornfromajar3222 Месяц назад

Thanks for sharing. I was at SMR Virginia Beach a couple years ago, used to be called Camp Pendleton. They still had the target range facing the ocean, but it’s abandoned and not used anymore. I thought that would be interesting having a range shooting out towards the sea. Far as I know, the Navy and Marines is the only one that does that anymore on ships when they’re underway.

Thanks for the well done teaching video. Great to see this video in particular because zeroing is some of what I've forgot. I qualified with m14 (1967). Now I have a Springfield scout squad (or squad scout whatever). Pretty much everything came back to me (which surprised me). But the eyes aren't what they used to be and I shake a bit. So I'm only good to 100y so far. Everyone recommends red dots etc. for the vision issue. But somehow that doesn't capture those good (and some bad) memories. So I'm sticking with the standard sights. Thank you. USMC 1967-71

@charliel6295 9 месяцев назад

About what I remember from BCT 1963. Battlesight zero is not for target shooting or sniping. It is for combat conditions. It is so if you aim center mass you will hit the target in a vital area from zero yards to about 300 yards. Who has time for sight fiddling while under fire?

@cornfromajar3222 9 месяцев назад

That’s correct. I basically read through the procedure in the field manual and thought it might be interesting to display on camera. The practicality of it for everyday shooters can be questioned and after I did this I had to readjust my sights for everyday shooting. Thanks for coming by!

900 Inches (25 yards) is what we used when I was in the Marines. They actually called the range the 900 inch range. It is important to know though that in the Marines, the sight picture we were taught was to place the blade of the sight below and just touching the 6 oclock point on the bullseye. If you put the blade at the center of the bull, you will hit the top edge of the bull at 200 yard.

@cornfromajar3222 3 месяца назад

Interesting. I fully accept that the marines as a whole take combat and weaponry more serious than the Army, (I.e. every marine is a rifleman first, whereas Army if you’re not an infantryman, cavalry, or special forces, then you’re not a rifleman). I really would like to see the army adopt more of a marine doctrine when it comes to marksmanship. Thanks for sharing and thanks for coming by!

@albertsnow8835 Год назад

When I was in the army we zeroed on what was called a Canadian Bulls Eye. The target was marked in small squares. The CBI was rectangular about four inches wide and maybe three inches tall and was black. Along the bottom row in the middle was one square left white. To zero from 25 meters the front sight seemed the exact with as the CBI with the white fit visible to make sure you were not taking too much of the black. A X inside a circle was about two inches above the aiming black. All bullets were adjusted to that circle for the ,M 14.

@GeorgiaBoy1961 Год назад

@ Wildkat-1 - Regarding the replacement of the M-14, the story I have seen and read in history is that Defense Secretary McNamara had it in for the army ordnance establishment and decided to put the national armories out of business. He was an auto manufacturing executive at Ford, with time out for service in the army air force during WWII, so I don't know where the guy got the idea that he was smarter and more-astute than military men who'd spent their whole lives in the profession of arms, but that was him.... he was an arrogant SOB, a real piece of work. McNamara liked the AR15, which later became the M-16, and pulled the plug on the M-14, which was at the time (circa 1962-1963) being turned out by Springfield Armory in Mass., as well as Winchester, TRW and H&R in the private sector. Army special forces had used the new weapon in Vietnam and liked it, and the Air Force wanted the new rifle to replace their worn-out M-1/M-2 Carbines, as they'd never adopted the M-14. McNamara's real crime, if you will, is not that he favored a newer design in the AR15/M-16, but that he pulled the plug on production of the M-14 pretty much acting alone and on his own authority, without consulting the service chiefs or other parties. The trouble was that the M-16 was very new and had not been sorted out in terms of defects or manufacturing problems making the rifles, nor its ammo. By 1963, the M-14 was being produced in large numbers and the rifles were working well in the field and in training where they were being issued. There was no emergency or sense of urgency necessary for their replacement. However, McNamara and his whiz kids with their slide rules promptly ceased production, while development of the M-16 was still taking place. Which means the ordinary Marine or soldier was left hanging out to dry. Many men - as you undoubtedly know - trained stateside with M-14s or even M-1s, and didn't see their first M-16 until getting to Vietnam. Once there, they didn't have much time at all to familiarize themselves with the new weapons, let alone become anything like experts with them. Big Green (the Army) and the Corps sent men into combat with them anyway. With the predictable result that there were severe problems almost immediately, and you know the rest. Literally, there were GIs who died in combat with jammed M-16s in their hands or at their feet. The scandal made its way back home in letters from the men, and finally a Congressional hearing was convened, the so-called Ichord Hearings of 1967, in which the whole sordid story finally came out of how McNamara and his specialists had bungled the introduction of the new rifle badly, and then how the DOD/Pentagon and the brass tried to cover it up. The whole thing was a disgrace from top-to-bottom. Eventually, the armed forces sorted out the M-16, but not until long after the last men had returned from SE Asia. There are a lot of Vietnam combat veterans walking around today, old guys who hate the M-16 ... and considering what they've experienced, probably with good reason.

But when it comes time to arm, train and equip the humble foot-soldier, the infantryman, all of the sudden, the funding cupboard is bare!

@geodes4762 Год назад

When the Army conducts a zero range exercise they typically use what is called a “Canadian Bullseye” target. This looks like a rectangle with a cut out slot. There is usually an “X” above the rectangle and one below. The one above is used to zero an M14 or an M1 rifle. The one below is for an M16 series rifle. The difference owes to the difference in muzzle velocity between the 5.56mm and 7.62mm rounds. This difference cause a marked difference in the trajectory of the rounds. The 5.56 has a much flatter trajectory than than the 7.62mm and is actually still rising as it passes through the 25meter point. We would normally fire three rounds and then go down range to check the shot group center. This was done until the center of the fired three rounds centered on the appropriate “X”. The M16 we used back in the 70s required a bullet to adjust the sights. The sights are adjusted in the direction you want the round to go. On the M16 the elevation adjustment was made on the front sight. There was an arrow with an “up” indicating the proper direction to move the round. The front sight actually went down to move the round “up”

@cornfromajar3222 Год назад

Excellent breakdown and thanks so much for sharing. I appreciate you coming by!

@explorerx6984 Год назад

There is not that much difference in trajectory between the 5.56 mm 55 grain round and the M80 7.62 mm round. The difference in impact points at 25 yards is mostly due to the difference in the height of the sight aperture over bore centerline between the AR-15 and the M-14. Yes, in both cases the projectile is rising at 25 yards (and at 100). I have never heard that sight called anything but a "Canadian Bull". There is no "eye" in it.

@geodes4762 Год назад

@@explorerx6984 A bullet follow the law of physics where its drop is calculated by the formula D=1/2g(t)sq where d is the drop g=32.2 ft/sec/sec t in this case would be the time it takes for the round to reach the target. You would really be surprised by the difference in drop due to the differences in muzzle velocity. I had an argument many years ago with a fellow officer who tried to say we could use the M16 sub caliber device to zero our M16. The subcaliber device used a .22 long round that had a muzzle velocity much slower than the 5.55mm. His argument was the 25 meter distance made the difference insignificant. I gave him the numbers and told him to put them in the formula. He finally believed me!

@muddybear9178 Год назад

The bullet does not rise, as soon as it leaves the muzzle gravity begins pulling it to the earth, I think what you mean is trajectory.

@michaelmichaelson8452 10 месяцев назад

There is a battle sight zero setting on the front and it should be set at that and left alone during zero. All adjustments for windage and elevation should be made from the rear sight. Once you start messing around with the front sight you will be all over the place and wasting ammo trying to zero.

@shochikubai8084 Год назад

Thanks for this video. But a question in after u sighted in for battle sight zero, did you adjust your elevation back down to zero? And add elevation as u shoot longer distances?? Instruction sheet with my socom 16 said to loosen elevation screw, move knob to zero and then retighen. I have not been successful in doing that. I mess up. Just wondering what u did after u sighted in.

@cornfromajar3222 Год назад

I don’t keep mine battlesighted, I basically keep it zeroed for fifty yards. I just did this video for demonstration if anyone was trying to use the Army manual. My range is pretty lame so I usually only shoot one distance or re-zero if I shoot farther. Serious M1A shooters would really call me out on that, but I just don’t shoot often enough at different targets to mess around with it. I wish I could be more helpful I’m definitely not smart enough with the gun though. Thanks for coming by !

2" above the center at 25 yards/meters equates to hitting the X at 250 yards/meters (because of the known "drop" ballistics of the 7.62x51/.308). This exercise is done so you can quickly go back and forth from the firing line to the target...and it is faster to only walk 25 yards/meters instead of walking back and forth from the 250 yard/meter line.

Using the wrong ammo though. Really should be firing 7.62 rounds. Says in my SA manual that the 7.62 primers are hard and mitigates the "slam fire phenomenon". Meaning a 308 round can go of when the bolt is closing due to the fact every time the bolt closes. The firing pin does leave a dimple on the primer. It's a small chance but if it slam fires. Your rifle will explode. I don't really want to hear any arguments. Just saying, that's what the manual says.

308 rounds have a chamber pressure of 60,000 psi while the 7.62 rounds are at 50,000 psi which is why you see different loads in the reloading data for the M1A. Recommendation is not to use 308 rounds because of the potential for damage. As for slam fires, reload if you can using Lake City or IMI brass since there is no difference between the two cases. Use a primer pocket reamer and you will eliminate the possibility of a round going off when it is not in battery. Throw away any commercial brass after firing them. You can reload the Lake City brass four times before discarding them. Look up the article "Reloading for the match M1A." Lot's of good info there.
