SIG Sauer Switzerland OEM Green SG55X side folding telescoping stock. This is the 3rd generation version of the 550 stock. The newest change on this stock is that it can now telescope for length of pull. The stock retains the same function and overall shape as previous generations and uses the same stock mounting system, button/latch, and butt-plates.

This stock will include a new production US made pin and washer. We are out of stock on Swiss made pins at this time. Both will work for mounting.

The Gen 3 SIG SG55X stock was released around 2013 to modernize existing contract rifles. Specifically these stocks were sold to update many Stgw 04 and Stgw 07 (552 & 553) models. The stock allows users to change the length of pull while still retaining the same ergonomics and folding mech that the older models used.

New old stock – Excellent condition: NO Packaging.
