JANES.COM review of our SAR 21 rifle

nismoS132 SG

it's 10m but the LAD and the scope are not focused on the same spot. otherwise you'd need to go to a large field everytime you zero your weapons.

Mr. Green no matter how good the SAF give some ppl will just say no good.

never blame the gun for not hitting the target, blame the shooter.

Looks like the training thinking soldier had fail in SAF again as no one seem to be doing the thinking at all. Laughing

CKtalon SG

somehow I dun find the scope accurate.. Razz
Target on the crosshairs, but the rounds fly too low and hits the ground.. Confused
I doubt it's my technique.. Laughing

Perhaps Tranche 3 (the Modular MMS Rail model in the 3G Army concept)should feature the floating red-dot reflex sight as standard.

Si Geena SG

That's what I said. They are not. They are parallel zero. The scope and the LAD are a distance apart. Their Point of Aim should also be the equivalent distance apart. Thus "parallel zero" The factory has a chart with the designated points on it to reference.

Using the large field, open range is the way to zero if you lack the factory facilities. However, this form of zero is only good for the range at which it has been set. It is not as flexible in application as the parallel zero.

Cool

I like this idea. But there are still "old skool" mentality regarding batteries and electrical stuff... From the ways things develop, it is the way to go.

More likely it's your technique.

What I experienced.... at different distances, you have to adjust your aim.

I'm going to have to go into Newtonian mechanics here... bear with me.

Anyway, the rifling (i.e. the internal grooves) of the barrels is meant to keep the bullet in a straight line. However, after some time, the path of the bullet becomes parabolic. To those who don't know what is a parabola, it is roughly the same shape as a semicircle.

This was what I experienced:

At 100m and below: The bullet travels in a more or less straight line. Thus you ought to be able to aim anywhere on the target. Obviously, try aiming for the middle. Don't try to be superman and aim for headshot (unless if it's Fig 15 of course) Mr. Green

At 200m: The bullet is in the upward portion of the parabola when it reaches the target. Thus, it will hit somewhere just above where you aim. Therefore, try aiming for the base of the target.

At 300m: The bullet is in the downward portion of the parabola. In other words, the bullet will hit just below where you aim. Therefore, you should aim for the top of the target.

That's what I experienced, and that was my reasoning. There may be holes in my arguments, though. Any comments.... anyone?

Your suggested trajectory for the bullet looks like the one i saw on a chart outside a range. So i guess its accurate.

i think its a good rifle though. Day/Night i took a rifle w/o zeroing at 100m at got 18/19 out of 20.

But some ppl's scope and LAD are obciusly not zeroed properly. They were hitting the floor most of the time!

I guess its a problem with ppl messing too much with the zeroing.

fudgester SG

That's the problem with zeroing shoots. The rifle may already be well-zeroed, but the incompetency of the firer may lead to the rifle being rezeroed (inaccurately this time).

If you don't hit the target don't just blame the rifle..... It may be you yourself who's at fault.

STK factory has a prototype sar21 wif that leh Razz

LazerLordz SG

I’m thinking on the lines of actually allocating that more rapidly.
