Outstanding product. As accurate as any high quality AR, and more reliable. For accuracy, it likes heavier grain bullets (62+) best, but will eat anything you can fit into the shell casing. This is the only reason it didn't get 5 stars from me. The factory 2-stage trigger is the best non-custom trigger I've ever pressed!

If you closely look at the machining that was involved, I believe it would be cheaper to mass produce for the military than the M16/M4. It breaks down simply, the handguards are solid, and there's no twanging buffer spring. It has all the best aspects of the AR and AK rolled into one.

Compares to the best M-4s I have owned but simple operation and tear down. Likes TAP 75gr or 69 gr for best accurrancy trigger almost as good as two stage RRA Tact. Entry I own. Yes the foregrip w/o metal rail is a drawback.

Seems to be a good solid weapon only drawbacks are:
1. Poor or no backup iron sights
2. Rails should be steel not plastic/polymer.

Love sig products. Excellent shooter

I havent got one of these yet, but im planning on it. Its apretty much the same thing as an ar-15 even the disasembly. When i get one im going to put a ecotech or somthing like that on it since its back sight is only put on one position. But its a great gun.

I have just purchased one and the first thing I noticed is it's durability. It is made to take a beating while remaining reliable. This is one of the best gas piston rifles out there.

Own this rifle. Better then the ARs /AR clones that are out there... only draw back is it needs metal rails.
