Runs good? Do you shoot 223/556 after to clear out any gunk?

Sorry. I forgot to mention that I built a dedicated upper for it so I bought the collar after.
I haven’t had any problems with it and even my wife and son enjoy shooting it.

I can’t remember where I got it from. It was around 1 1/2yrs ago but I’ll see if I can find the site.

Only other site I found was Brownells, but out of stock. I was able to order one through the manufacturer. I asked them to send me a PayPal invoice.

Shot the CMMG conversion kit yesterday with cci minimag and SV. Both functioned well. The SV POI was more near to my 223 POI without changing my optic windage or elevation not perfect but pretty close. The SV also was more accurate although I didnt shoot that much 22 yesterday. I also had federal HV 40 grain but didnt shoot it. Groups were maybe 3 inches or more at 50 yards
I'm satisfied with it. I'm going to use it for plinking and doing drills at close range on a friends farm. If I want better accuracy with 22LR, I can use my bolt action.

Glad to hear the SV’s were reliable and accurate. I bought a case last year but didn’t get around to shooting them yet.
