Does anyone know where you can find this stock? ...or any information on it? Thanks in advance.
I found the pictures while perusing the web for SIG 550. There was no response from either of the posters. They look like some version of the extendable stocks found on 553's and appear to only be attached to the American early lower receiver that accepts buffer tube stocks. Anyway an interesting vignette/mystery in this hobby.Never seen it before. Where did you get the pics from? That'd probably be the best place to ask. Either way, it looks like an AR stock that mimics the swiss folder look since it appears to attach to the receiver extension tube hole in some capacity.
