Are you kidding? What is impractical about that? To me, that is a 100% practical minimal rifle. I love the concept too: put a rifle in the smallest, handiest, most ergonomical package you can - and stuff like this results! If I were in the urban variety of the brown stuff I would LOVE a rifle like that.
The only gripe I might have would be the magnifier. Is that beast accurate enough to justify it, CR5? If so I might consider a true scope instead - but that is just me picking the fly chit out of the pepper. Any gun you make like this has to be tailored to its user and if it makes you a better shot then you really have no choice. I would love to see a range report that would include accuracy testing off the bench if you are so inclined.
An accuracy test with multiple ammo types will be coming next chance I get to go to the range.
The only thing the short barrel should give up is velocity, accuracy should be pretty good under 100yds.
As for the magnifier, I don't really need it or plan to use it much but since I have it I may as well try it out. It's only a 3x mag so it just helps me be a little more precise. I will probably use it when I do the accuracy test and I'll probably do that at 50yds instead of my usual 100yds.
Practicality is the same as any other AR I guess since they are all range toys. It's almost too short though as it's kinda hard to get a grip on without having my fingers end up on the gas block. It's fun though, another couple range trips and I'll know if I'm gonna keep it or not.
