My SP10 has averaged below moa and has shot many 1/2 moa or better groups also - all factory ammo. I just recently hit the 200 round point with the rifle and began load development. I'm now seeing 1/2 moa and occasionally better pretty regularly with one load I've settled on for the time being. After adjusting the gas block for that load, I couldn't ask for a smoother shooting rifle and brass comes out pristine. I'd put it in nearly the same league as my LRP 07 made in early 2018. Neither has a +2 but I've fired a newer JP which does have the +2 and neither of us shooters could tell any difference. Just my .02...

You think? My 6.5 SP-10 is rifle length with an adjustable. Shoots fine. Thoughts?

Are you thinking more dwell time is needed?

I've been eyeing a good 6.5CM gas gun and the Seekins checks near all the boxes for me. Timmney, flat-bottomed handguard, billet receivers, good brake, etc. A proof Carbon barrel and maybe a Surpurlative Arms gas block if the factory barrel ever gets shot out.

People are fucking ridiculous with this shit as if...

They have a $2550 rifle and then bitch because one is 2x as much and they claim the BARREL Profile is different, the gas block is the $60 vs the $120 one, so order the $120 model, ask for a different profile, you can spec it.

The SP10 works great, it's super accurate, it's the base rifle for the GAP10, it's a proven winner on so many levels.

Add in $60 and order the other block, LOL D'uh.

Unbelievable what people will bitch about, oh, I had to use an Allen vs the lever, it's different, the M is $3800+ the non-M is $2550, add in $60 and change the block, you still win by a wide margin.

Glen uses Rock Creek Barrels, they both have a Rock Creek Barrel on them, one is a slightly heavier profile, BFD
How does GAP turn the SP10 into a GAP10? Is it mainly a barrel replacement?
