MGI modular magwell lowers now sold separately
| by Max Slowik
MGI Industries is now selling modular AR-15 lowerreceiver
systems separately from full kits. Originally designed for the Hydra rifle
system, the MGI Modular Lower Receiver sports interchangeable magwells, for use with AR magazines and AK mags.
With these lowers it’s possible to build a rifle that can happily go from 5.56 NATO to 7.62x39mm with none of the potential problems using straight-walled AR magazines. It also opens doors to AK shooters who are already magazine-rich interested in getting into the AR game.
On top of that MGI manufactures AR pistol-caliber carbine magwells for shooters interested in 9mmLuger
builds. These magwells work with common Colt-pattern stick magazines.
With all three magwells and the right complete uppers and bolts one lower could easily host not just 5.56, 7.62×39 and 9mm
uppers, but all of the other AR and AK cartridges from 6.8 Remington SPC, 5.45×39 and even the original hybrid cartridge, 6.5 Grendel, all with the magazines intended for the rounds, not modified or altered into something “good enough.”
Interesting enough of a idea if it works . SJ 40
