I have both a GAP10 and an LRP07 in 6.5 CM.
You can't go wrong with either. The JP is a little lighter, the side charging handle is really nice, the fit and finish is damn near perfect and the LMOS carrier and JP bolt are works of art. No slouch in the accuracy department either. The GAP10 is a really nice piece too, I wish the JP lower had the ambi bolt release the GAP10 does. The JP has a lighter & softer recoil impulse than the GAP10 but the JP has a slightly larger brake and the low mass operating system compared to the GAP10 with a smaller Titan brake and a full mass carrier. The silent captured spring in the JP is neat, very smooth and no noise coming up from the buffer when cycling.
Based on my two rifles I would give a very slight edge in accuracy to the GAP10 but we're splitting hairs-- both are extremely accurate, I've managed 1/3 MOA 5 shot groups at 300Y and 1/2 MOA 5 shot groups at 550Y with both of them. Both are easily more accurate than I am able to shoot consistently with a large frame gas gun.
Since wait times were mentioned, it took about 8 months to get the GAP10 (ordered mid 2012) and JP delivered the LRP07 in under 8 weeks (ordered May 2013.)
Regarding your optic choice, unless you already have the NF 8-32 & BORS my recommendation would be to skip the BORS and put that money towards a better base optic-- for the price of a NF 8-32 + the BORS that puts you in the range of a Kahles 624i, S&B 5-25, S&B 3-20, Steiner 5-25, NF Beast, etc, all of which will be a better optic than the NF 8-32. Or you could get something in the $1500-2000 range and spend the money saved on ammo or other accessories!
