My ongoing 12.5" Grendel build

[PigOPs]

Here my first (and only) 5 shot group with factory SST. The lower left was a called flyer. My heart was beating hard cause I was excited and should've calmed myself more. What I am most excited about is I should be able to find a handload that's even tighter. Not bad for a chrome-lined barrel that I paid $200 for (after chopping down). This gun puts a smile on my face every time I pull the trigger...
