Want a Colonial Marine Corps M-41A Pulse Rifle at home? You can get pretty close with the Manticore Arms Ripley Rail.
If you’re a fan of the Alien movie franchise, there’s a good chance you’ve thought about owning the iconic M-41A Pulse Rifle used by the Colonial Marine Corps in Aliens and Alien 3. Sure, replicas are available for purchase, and some enthusiasts have even gone the extra mile and built models capable of live fire using a Thompson as the base (like the original movie props did), but that’s difficult and expensive. If you want an easy shortcut lookalike, you need to check out Manticore Arms’ Ripley Rail.
The Ripley Rail can be mounted to just about any standard AR with a Picatinny rail upper receiver, and it will instantly transform your carbine into something that looks suited for space combat against xenomorphs. Well, at least the front half of the gun.

Made of 6061 T6 aluminum, the Ripley Rail features an integral carry handle with front and rear iron sights as well as the hole for mounting AR carry handle scopes. The aluminum forend also features plenty of usable M-LOK slots on its sides, top and bottom for mounting accessories as well as just helping to match the aesthetics of the Pulse Rifle. A ribbed polymer foregrip helps with that, too, and it gives you something to hold on to. The forend sports a Platinum Cerakote finish, and the carry handle is available in either OD Green or Carbon Black Cerakote.

Manticore Arms says the rail is designed for use with rifle caliber barrels 10.3 inches or longer and blowback pistol caliber barrels 11 inches or longer to ensure the muzzle clears the handguard, although shorter barrels can be used in conjunction with a suppressor as long as its diameter is 1.5 inches or less so it fits inside the forend.

The Ripley Rail won’t magically convert your AR to fire 10mm caseless armor-piercing ammunition, but it will make it look pretty damn cool. MSRP is $495.
