The last time I wrote about the SIG 556R, the specs for the rifle had not been published.
|Weight||7lbs (without mag)|
|Other Features||SIG Red-Dot|
The 30 round 7.62x39mm magazines cost $28 each. The SigSauer.com website only shows a model with the red dot sight. A iron sight kit (Rotary Diopter Rear & Hooded Front Sight Set) costs $142.
UPDATE: SIG tells me that regular AK-compatible magazines work with the 556R.
