I'll hopefully have the wampum on hand in a month or two to order a JP CTR-02, so I'm trying to figure out exactly what I want.
This will be in .223, and I'm not yet sure if I want the .223 chamber or 5.56 chamber.
The rifle will be used for local 3Gun matches in Colorado, RM3G, SMM3G, the ITRC in Gilette (if I can find a partner), and maybe NA3Gun or MGM if I can get the time off.
It will be set up for "Modified/Tactical" class most often, using a TA11, will have the BC comp installed, and the low-mass bolt carrier assembly.
My question is primarily in regard to the barrel profile. JP offers three barrel choices appropriate for a 3Gun rifle: the Ultralight 18" (.500 under handguard, .750 at gas block to muzzle, about 6lbs), the Lightweight "Medium" 18 and 20" (.750 under handguard, .936 at gas block, .875 to muzzle, about 7.5-8lbs). I think you can only get the 1-in-8" twist on the 20" barrels.
Which would be the best choice for a 3Gun AR to shoot those matches? I don't mind length necessarily; I am probably more sensitive to mass. I would prefer to be able to shoot the 75/77gr bullets if the need arises.
Those of you with experience with the JP barrels, which length/contour do you prefer and why?
How about experience mounting a TA11 on a CTR? I'm currently using an ARMS #19S on my Rock River.
thanks much,
Zak Smith
