Windham Weaponry has entered a product onto the market, that is a reintroduction of a product that came out around eight years ago or so. It is also an expansion of their MCS1 upper receiver kits. The MGI Hydra was a proof of concept rifle that by changing out the bolt carrier, barrel, and magazine well, a shooter could switch from a number of calibers, from 5.56×45, 7.62×39, 9mm, and .45 ACP within literally minutes, by pulling out on a knob on the handguard, switching bolts, and then clicking in a new magazine well for the intended cartridge, with different adaptors for AK, Glock, AR15, and M3 Grease Gun magazines. There were a number of different versions as well, some in pistol form, and in more calibers. The product didn’t gain massive support, but it appears that Windham Weaponry feels that the company can make it work this time around, just in time for SHOT. They’ve added .300 BLK to the caliber availability and have expanded the types of packages that a customer can buy the conversion system in. The basic package comes with a 5.56x45mm and a .300 BLK barrel, that goes for $1738, called the RMCS-2. The RMCS-3 comes with a 5.56x45mm, .300 BLK, and 7.62x39mm barrel and goes for $2391. The RMCS-4 has all the above calibers, in addition to 9mm, and is going for $2971. All of these kits have the complete rifle in them.
Windham, ME – In one of the most exciting announcements to come from Windham Weaponry since its inception in 2011, the Company invites attendees of the 2016 Shooting, Hunting, and Outdoor Trade Show (SHOT Show) to visit them in booth #10376 to see their new multi-caliber AR Platform rifle series.
The Windham Weaponry Multi-Caliber System (MCS) is a groundbreaking new rifle that allows the user to convert between calibers by changing out the barrel, magwell, and bolt carrier group and utilize the same lower and upper receivers. The MCS is available in three configurations, and offers up to four caliber options in one AR platform rifle.
