Great product, good quality and perfectly matched to the Sig P556. Very impressed with the build quality and timeliness of the transaction.

Stock is well made, install takes 5 minutes. Feels close to the 552 european folder in length and overall shouldering. Locks firmly in place. No walk or talk at all. Solid! Definately get it with a larger pad. These rifles all have a tight shouldering as is, but it is still a bit short for my stance. Adding a veritcal grip to the handguard does help for anyone experiencing this. The stock folded does not go far enough to lock up on the handguard "nub" on operators right side. I think the proprietary sig ones do, but it is not a dealbrwaker for me. At this price 5 stars. Fast processing and shipping. Would reccomend.
