There's a really long artical on them in the Rifleman Mag. Has one one the cover. They even covered it in sand and mud to test it. Looks pretty nice.
I just read that last night, but for the life of me do not se a date where it will be available. I even checked the Sig site, and no mention of it at all.
yes I read the same article, it looks pretty sweet and again another with the adjustable gas port....I wish my LWRC had one of those....even though its already a short stroke piston. Im still partial to the 556 swat...I really like those and the stock folds. I think that is nice feature in a rifle that doesnt look like an AK variant
