Very excited PSA has shipped my stuff .

So stupid question . I have never put a rifle together from separate parts by different " Makers " Is there anything I need to do or check prior to shooting it ? I know about the safety checks but past that I m not sure .

Thanks ,

The only thing you need to do is make sure the upper and lower fit well together. If they are loose there are plastic or rubber inserts you can use to tighten up the it between them. Mil spec insures that most parts are mix and match with little to no custom fitting.
