The only benefit of a JP is the side charger part (more parts to break) and it already comes with a low mass bolt carrier.

The LaRue OBR is more accurate and has two gas port sizes when you shoot suppressed.

Both JP and LaRue heavily support the shooting sports. Both John and Mark are good men I have met both and spent plenty of money with both. I have shot both the LRP and OBR. For a semi in 308, LaRue gets the nod. In 223, JP wins.

I just rebarreled my OBR to 260. Gonna check for accuracy tomorrow afternoon.
