Louis, it has an adjustable-height cheek riser, but no it does not adjust for length of pull.

Just the cheek riser. The rest of the stock doesn’t adjust. Stay safe and happy plinking!!

Louis, no. Only the cheek piece is adjustable for height once opened. I recommend the adjustable Archangel Stock : brownells.com/shotgun-parts/stock-forend-parts/stock-sets/adjustable-stock-sets/archangel-870-tactical-shotgun-stocks-prod128885.aspx

The only thing adjustable is the cheek rise. The stock itself for length of pull isn't adjustable. Hope this helps.
