We stock JPs at Arnzen and have had nothing but rave reviews. They're some of the most accurate ARs out there - with the right ammo, people will often get sub 3/4 MOA with their 308's and 1/2 MOA with their .223/.260/6.5 rifles. They're very popular with 3-gun competitors for their accuracy and reliability.
We're out of stock at the moment, but here's some of the JPs that we've had:

There's a short list of guns that have been through the shop that I want to buy for myself, and a JP SCR-11 is definitely on it!
