Sig Sauer 556 Range Report *PICS*


April 10, 2010, 09:42 PM
Went out today to break in my new Sig 556 with Sun Optics USA zero power sight, kinda looks like an ACOG but deffinitly isn't! ;-)
All shots were at 50 yards with Monarch 55gr steel cased .223. Only one failure to fire out of 280 rounds. The striker hit the round but no combustion. I'm gonna blame the ammo, not the rifle.
After many, many, many, many, many adjustments I decided this was as close as I was going to get to a true zero.
This was my second target after the zeroing in process. 30 rounds all inside the square!
Pretty good grouping except for those two little wanderers there on the bottom right.
Third fresh target after zero. I was having trouble hitting the smaller squares in the corners because at the 50 yard mark the reticle completely occluded the target making it next to impossible to visualize. Then, out of nowhere I got the idea to reduce the intensity(power/brightness) of the reticle so I could kind of see thought it and still be able to put it on target. I couldn't believe it took me so long to figure that seriously was like a light bulb moment, I felt kind of silly about not thinking of it sooner.
After that minor adjustment I wore out that top right!!!!
30 rounds in each square.

All in all I'd have to say that I am extremely pleased with the days events and the accuracy of my current set up. hopefully it will be just as accurate at 100 yards once I get either a powered scope or a magnafier for my current sight.
ohhhhh the possibilities

Carter-I didnt notice it too much. Then again the only reference I have to compair it to is the Army issue M-16 I havent shot in over 6 yrs.
I suppose it did well by the looks of the targets.

The Real Mags-Stand by, I'll get you a pic here in a sec.

Quad Rail, stock on this unit.
Sun Optics USA zero power sight. $90.00 at last gun show, pretty decent for the price in my opinion.
Also, the factory rotary Diopter iron sight.
The reticle of the Sun Optics sight

Is it me or does that SIG556 have a very short gas system??

Looks like the Patrol SWAT model, which does have a short piston system compared to the Classic or standard 556.
I have the Patrol version myself. A little less nose-heavy and a tad easier to maneuver with.
Yes, the short system produces a little faster wear, but it will still last a long time.

Isn't the gas block adjustable anyway?

It is. Look at the pics. At the end of the forearm there is a stainless notched piece with a hole in it. That's the piece you turn to adjust pressures.

According to the manual (yep, I actually read it :)), if your rifle fouls or you start experiencing any malfunctions you turn the knob to increase pressure which is supposed to take care of any gas system issues. Okay, I'm paraphrasing, but you get the idea :D!

I've never had to turn mine since my 556 hasn't had any issues whatsoever...except an uncanny ability to eat a lot of ammunition!
