PJS,
When I got my DAR it was $300 and a very good buy for the price. It will not match my Daystate Huntsman but it was 30% of the cost so have been very pleased with it,
At 50 yards the Daystate has averaged .77" 5 shot groups at 50 yards (45 groups) using Crosman 14.3's. Using the same pellet in the DAR I got 1.08" for 5 groups. I use the DAR for plinking at 25 yards so did not do much testing at 50 yards. At 25 yards, the DAR produced an average of .46" for 41 groups using that cheap Crosman 14.3 pellet. That is better than a lot of .22 LR will shoot if people are honest and record EVERY group.
At the current price of $500 the DAR is still a decent option. I like that it has a wooden stock and does not need an aftermarket moderator. The trigger on mine is not great and that may factor into me not shooting it better. The trigger can be easily improved but I have been too lazy to get it done. I spend most of my trigger time with the Daystate.
If you want a serious PCP rifle, go for the Daystate. They are $1100. You will want a moderator for it. I got a Donny FL (IIRC $150). I have a buddy who is a competitive shooter, and he is getting 1/2" groups at 50 yards with JSB heavies.
I wanted something that was accurate and cheap to shoot and PCP's accomplished that goal. It costs me about $15/k including pellets and air.
