Picked up a new RPR yesterday, cleaned the barrel, inspected the trigger mechanism, mounted a Vortex Diamondback HP 4-16 BDC, installed my Axion suppressor and hit the range today.
What the bore was like out of the box. It got the solvent, brush, patch solvent, brush, patch, Iosso brushed, and numerous patches to get it clean.
Also found an E-clip was missing from the sear pin, after reinstalling the trigger in the receiver I understand why.
The rear action take down screw wouldn't accept a standard allen wrench, had to use a ball head wrench to get it loose, then swapped it out with a new screw.
Ready for duty.
Bore sighted it the old fashion way on a target at 25 yds, first 5 shots using SK Std+
Went to 50 yds and the next five rounds got me excited.
That was the best as the next 18 5-shot groups didn't hit that .255" center to center group, but it delivered numerous .5" cc groups. I started trying to make it shoot after that first group and was tensing up and influencing the rifle too much, the 9" bipod is too tall for bench shooting requiring too much finicking with the rear bag which didn't help either.
The trigger pull started increasing from my measured 2.5 lb. pull, it probably went up to 4.5 lbs. after group 12 so I ran the adjuster all the way in and backed it out. The first shot on after that I touched off prematurely, the trigger was very light. Checked it when I got home and I was surprised.
All and all I was very pleased with the rifles ergonomics and function other that the ejector would leave a round laying on top of the magazine if the bolt isn't pulled back with speed. My RAR Target in .17HMR will eject a case easily going slow, so I need to investigate. No extraction issues and solid consistent firing pin strikes.
As dirty as the bore was, I ran two dry patch after the first 30 rounds and the second one was surprisingly clean, after the next 70 (50 of CCI SV) I ran another dry patch which wasn't as dirty as the first and flipped it over and ran it through again and it only had a light trace of residue.
My goal for this gun is to convert it to .17 Mach 2 for digger squirrel eradication in an orchard, now I'm thinking buying another one might not be a bad idea. LOL!
All said, I'm very happy with the gun for the first range trip.
