Description
Product Overview
The Sig Sauer SIG556 HOLO is a semi-automatic 5.56 NATO rifle built around a two-position adjustable gas piston operating system and multi-lug rotary locking bolt. Its 16-inch cold hammer forged barrel has a 1:7 inch twist and a 1/2x28 threaded muzzle with an A2 flash suppressor. A holographic red dot sight is mounted to the Picatinny rail-equipped receiver, while flip-up combat sights provide an additional aiming option. The rifle features a vented tactical tri-rail forearm, ambidextrous safety, smooth two-stage trigger, and an M4-type synthetic stock that both collapses and folds. It accepts standard AR-15 and M16 magazines and includes one 30-round magazine.

This is a perfect rifle. When you pick this rifle up it feels perfect in its handling. It shoots great and no problem shooting all ammo. Buds has the best price and delivery.

WOW! That's the first...
WOW! That's the first thing I can say! Bud's offered this model at an incredible price, and I had to jump on it. The 556004 model does come with the SIG Holo sight, the newer version of the charging handle, and the folding/collapsible stock. However, the stock is the hollow type as seen on the swat models, not the one seen in the picture here. Also included were a bright blue gun case (attention grabber SIG?), lock, larger recoil pad that adds an extra inch, and one 30 round SIG mag. The SIG is incredibly easy to field strip, and even has updated push pins, so no more need to unscrew anything. The flip up rear iron sight is good enough to get the job done, though will likely be replaced soon. I love that it comes with picatinny rails all over the front rail. I shot 100 rounds at the outdoor range yesterday with some friends, and we were all very impressed. They are both owners of AR's, and they kept commenting on how solid it felt, how little recoil it seemed to have, and how much better it held target. Yes it is heavier than a standard AR, but not heavy enough to affect your shooting enjoyment. I am incredibly happy with my purchase, and was reminded of that when I was able to consistently hit a 2x2 steel target at 300 yards, even using iron sights. Thanks Bud's, and thanks SIG for such an incredible gun!

Awesome Gun. It was...
Awesome Gun. It was better than described. Came with the hollow collapsable stock and red dot sight. Very Happy with purchase. I was overcharged by accident they corrected right away, with no problems. I saw complaints online about Buds in forums but in my opinion they have no merit. Will likely do business with Buds again.
