SARRP stands for Special Application Rifle Retention Platform. It is a kydex holster for an AR platform.
It is made by Ten-X tactical. Ten-X is a small company out of Southern California and primarily make ammo. They do have a few tactical products like this AR holster. No clue as to the cost as there doesn’t seem to be a price on their website.
From the videos below I think this holster would be useful for a SBR or Pistol AR.
You can see how it is utilized in this video.
