Attaching the UPR-15 bolt action upper is just like changing the upper receiver on any AR-15 rifle. To do so, simply remove the two retaining pins out of the lower, and pin the UPR-15 right back in place. Head to the range from there and put some rounds through your new long-range, precision AR-15 rifle.

We are continually working to keep this list as up to date as possible. At this point in time, if it is not a standard AR trigger or one listed below, DO NOT USE IT. There is a possibility that if the trigger is pulled, with the bolt open, the hammer may fall before the bolt is closed completely and the lugs fully engaged. This may cause serious damage to the rifle and/or injure the shooter. Due to the many trigger variations available, it is impossible to guarantee they will all work safely with our upper. Again, we advise that if it is not listed here, DO NOT USE IT.

Caution

Be EXTREMELY CAUTIOUS when working up and firing hand loaded ammunition. Always start with a light load as shown in a reputable reloading manual. As soon as any sign of excessive pressure is encountered, (flattened primers, punctured primers, bolt is hard to open, etc.) reduce your load immediately to a safe level. If you are not experienced in handloading, make certain that you acquire the necessary expertise before proceeding. Inspect each piece of brass to ensure your brass is safe and free from any defects such as cracks in the neck, shoulder or base. Make sure that each piece of brass is trimmed to the proper length and that all case dimensions are correct for your particular barrel(s) chamber prior to loading. The specific caliber of your barrel(s) will be marked clearly on the top side of the barrel near the muzzle.
