These are kinda different guns. They look like custom guns but they are called "Grendel SRT-20F" I believe. They are a Sako AII action with a Douglas 20" half fluted heavy barrel. They have an internal magazine that holds 8 or 9 in .308. THey also have a folding stock the folds under the trigger guard. If you have one or know someone that does contact me.
