Still haven't shot the PR20,but thought I'd post up my impressions so far.
Sticking points:
1. The sticking charging handle latch was cured with a small drop of CLP.
2. The takedown pin detent doesn't assemble from the rear, it assembles from below like the safety detent (maybe all .308 ARs are like this?). The hole for the spring is threaded 6-32, but no retention screw was used to retain the spring. This was alleviated in short order by shortening the spring and adding a short 6-32 set screw.
3. The safety/selector lever wasn't clearanced enough on the backside to clear the boss on the receiver, and wore the finish off very quickly. Swapped for another safety lever and the problem went away.
Observations:
1. I wish it was offered with an A2 stock. I ordered mine with the collapsible Rogers stock, since the optional UBR didn't appeal to me Swapped it out with an A2 assembly (you'll need a .308 rifle buffer and spring to do this).
2. I opted for the LFA Muzzle Rise Eliminator, which seemed like a no-brainer at $40. I don't see this as an option on their current webpage, however.
3. I also opted for the Nickel Boron BCG, which again seemed like a no-brainer at $40.
4. Shipped in a hard case.
My opinion so far:
Despite some minor annoyances, I'm not ready to say this isn't a good deal. If you MUST have perfection out-of-the-box, it probably isn't for you. If you're not unwilling to do a couple minor tweaks, I don't think you'll be scared away, especially considering the price point.
Obviously, a rifle that won't shoot well isn't a value at ANY price point. I'm not sure when I'll get a chance to shoot it, but as mentioned above, I've got 200rnds of 5 different types of ammo. I topped it with a Vortex Viper PST 4-16x50 in an Aero mount.
I'll report back once I've sent some lead downrange. In the meantime, I can answer any questions anyone may have about the rifle itself.
