The following is the third in a series of range reports that center around my build up of a SIG 556 rifle. This report will center on the addition of back up iron sights as well as the first shots with some better quality ammunition.
The previous range reports can be found here.

Since the last range report I have made two changes to the gun.
1-I have added a GG&G A2 BUIS and a Samson flip up front sight.
2-I have added a YHM 1/2 inch riser in order to co-witness with the Aimpoint.
The rifle as she looks now.
Before I begin with the accuracy testing I want to discuss the three new pieces of steel, namely the irons and the riser.
All three are very high qulity solid pieces and went on with no problems. There was no loosening of screws, no issues what so ever. The Samson front sight is pretty much the only game in town but it looks good and works well so it is not some cheap quick to market piece of garbage. It is a quality piece.
Zeroing the irons was exactly like zeroing any A2 sights on an AR15, which I believe to one of the easier sights to work with.
Todays shooting was done in roughly 75 degree weather, overcast, slight wind moving laterally. The targets used were Dirty Bird Splattering Targest from Bass Pro (Cheaper then shoot and see's by quite a bit). The ammo consisted of 60 rounds of Remington 55 grain $5.99 a box cheap stuff, 20 rounds of Federal Ballistic Tip 55 grain good stuff and 20 rounds of Remington 55 Grain AccuTip good stuff. These can be seen below.
After sighting in the sights and then the aimpoint I was able to get the following results. Please understand that my rest is a small nylon carry bag stuffed with rags and I am not a great marksman with irons or non magnified optics. Also understand this SIG was built for shooting at 50 yards or less and to be more CQB oriented than match accurate. All targets below were shot at 100 yards. There were no failures of any kind. The gun runs FMJ, polymer tipped, and HP without missing a beat. The Aimpoint is a very fast and very well made optic that does NOT wash out in the sun.
100 yards, cheap Remington $5.99 55 grain iron sights. About 2.5 inches CTC.
100 yards, cheap Remington $5.99 55 grain iron sights. About 2 inches CTC.
100 yards Federal 55 grain good stuff Aimpoint. About 1/2 inch in the bull and a tad under an inch for the other group.
100 yards Federal 55 grain good stuff Aimpoint. About 1 inch for the right group and about 1.5 inches for the group above the bull.
100 yards Remington 55 grain Accupoint good stuff. 5 shot group is about an 1 inch with the flyer and about .75 inches for the 4 shots together. Other group is about .75 inches CTC.
Well there you have it sports fans. Next ammo to try is some heavy 69+ grain stuff and move from there. I will probably order some Black Hills match stuff. For my purposes though the practical accuracy is way more then I need and the gun will be a blast to just go out and plink with, while being just a bit different then the other guys AR.
I have said before and I will say again it is easier to shoot an AR15 well. I love the SIG but for pure accuracy it seems a high end AR15 is a better way to go.
