AR15 Uppers/Conversions

So, after thinking about my whole AR15 project I started thinking about just how many conversion kits there were on the market. Well, there are a lot, and lots of them are batshit crazy.

Of course, the P90/5.78mm conversion kit...













The .22LR target shooting kits (there are like 100 of these) notice the barrel of the .223 is indeed more or less the same size as a .22lr barrel, and the follower on that mag is tiny.






















Here is the 9mm conversion, which you can also purchase a dedicated lower for that accepts Glock magazines (such as the 30rd g18magazines) I've heard a .45acp model can be had as well.














This one was featured on futureweapons, the .50beowulf conversion












.223 and .50Beo comparison










There is also an insane .50BMG conversion kit that turns it into a bolt action sniper rifle, also has videos on youtube











A dif model (looks old), rear pin removed









There are also 7.62x39 conversions to shoot AK ammo and leagues of others to choose from, if you get the .308 style lower end you can shoot all kinds of magnum hunting rounds too.
