What carry handle for national match

[drjoker]

Rock River Arms website national match A4 Ar15 says that you have 4 choices for a national match carry handle rear sight; 12x12, 0.4: 12x12, 0.3: 14x14, 0.4: 14x14, 0.3. What's the difference? Which one should I get?

I would like to buy a national match rifle for national match competitions. It should be optimized for the competition. I used to compete as a youth, but my last competition was many decades ago with a bolt action rifle, so please excuse my ignorant question as I've never owned a "black rifle" before. I basically want to buy the minimum cost rifle necessary to get me into the "masters" level of competition.

Thanks.

1/4 * 1/4 sights allow greater precision - only downside is you need to count twice as many "clicks" when moving among 200, 300 and 600 yd lines. Most experienced shooters get the 1/4.

The .04 refers to the aperture opening - smaller allows greater depth of field BUT also allows less light in. As a *really* general rule, older eyes will benefit more from the extra light - I'd get the 1/4*1/4 with the .04 aperture.

The apertures just screw in so you could get a couple of different sizes to try.

You didn't ask but the front sight post is .052 on a NM upper from RRA and the sight is slanted (low side to the front). Those posts are also available in in larger widths as well as round. Because of the slant cut, the std post requires a full rotation when it's adjusted - that's 5 minutes up or down in a rotation. Start with the std part and just be aware that alternatives are available.
