Great build!

What magazine attachment are you using on the XCR mags?

 

[Longshot84]

Yup, I agree. Another beauty from id64. That is one ###y machine you built there.

 

[Thringer]

Nice rig man, I know it's an older design but I love the troy alpha rail.

No problems with light primer strikes out of the G2S?? I had to swap mine out for a standard trigger with heavy hammer spring to make it 100%.

 

[id64]

Not a single problem with G2S. This bolt came with custom firing pin that protrudes farther that a regular 556 pin would and it's fatter.

Looks good!
How's the accuracy with that NEA barrel? What size gas block and is it mid-length?

 

[id64]

So far I've got the best results with Russian surplus ammo, about 1MOA and less at 100m. PMC works pretty good as well. Romanian and czech ammo is so-so. Gas block is the regular 5.56 low profile with carbine length tube.

1 MOA or less @ 100 meters! I'm impressed.
I cannot even get a bolt action to shoot surplus that good.

I'm convinced that the carbine length gas port and 7.62x39 is the most reliable setup.

Geissele uses full weight Springs on all their triggers. However they do use a lighter hammer. That probably was cause of light strikes, rather than spring weight.

I was quite surprised myself. Haven't had a chance to reproduce this result at 100. Might take it to the outdoor range soon to confirm
