SOLD PROOF AR10 Barrel - Carbon 6.5CM w/ Seekins Gas Block

[sethrrows]

New PROOF carbon AR10 barrel - 22” 6.5CM +2 gas system with a new Seekins Precision select adjustable gas block. Everything is new and unfired, but I did have it assembled on my SP10, so it does have some marks on the gas block journal. I pulled it back apart to swap the rifle to 308 instead.

Dang so tempting. I have a SP10 in .308, so assuming everything headspaces (as it should) I shouldn’t have to change anything on the gun except the gas block and the barrel correct? Is there a specific wrench to the SP10 barrel nut?

 

[sethrrows]

@ChiefSillyHorse , You are correct. The original barrel on my SP10 was 6.5 CM rifle gas, I checked the headspace with my og bolt, pulled the old barrel and put it back together with the Proof. For the barrel nut you’ll need a 1 3/8 crow foot wrench, you can confirm that and their torque specs on Seekins FAQ page on their website.

Response returned, looking forward to using this barrel and seeing if there is an accuracy increase over the factory barrel!
