Just swap this drop in conversion with the bolt carrier group from your 5.56/.223 chambered rifle and you will be ready to shoot .22LR.
For best performance use a Mil-spec Un-notched Hammer as notched hammers might cause slight function issues.
36 grain plated nose bullets (The Cheap Stuff) have proven to be the best choice for function.
No Other .22 Kit Ever Worked So Well or .22 Lr Semi Auto Rifle for that matter.
Where this conversion works better than my old Ruger 10-22 even 22 Lr Ammo goes off much better from the harder firing pin strike. So that ammo that you had to cock the .22 a few times to go off this conversion will shoot.
We can't say enough how well this kit works
Works With All .22 Lr AR-15 Mags there is a standard magazine for the .22 AR's and this kit uses that mag mags made by Blackdog, CMMG, Sig Sauer,Chiappa,Promag,Stag, And Many More Uses All Ceiner Style
(It does Not work with S&W, Walther Style,Colt Mags)
