The replica is on sale now for $400USD with shipping set for early 2018, but you can claim one today with a pre-order deposit of $99. This is TriForce's first Fallout product, but you can see some of their other video game weapon replicas on their website.
If you can't afford TriForce's replica, you can always get the Alien Blaster in Fallout 4 using our wiki.
