PSA has been working on firearms for a few years and now there are some interesting variations of ARs available. First is the KS47, an AR that takes AK magazine.
Initailly it looks like it's from CMMG, but there was no way to comfirm who makes this rifle. This rifle will come with Key Mod rail, but also in classic handguard model.
PSA also has a 9mm AR they have been selling for sometime. It works with their 9mm upper and some other variants. It uses 9mm Glock magazine
