Accurate and well balanced

I'm still fairly new to the building game and wanted to gave KAK barrels a try as they were affordable.
I went with 13.9" length and pin & welded a break on to get my sweet 16 rifle. I gotta say I'm very pleased so far. With 250rds through it (mostly steel) it has performed very well. I have had a few stuck cases but don't fault the barrel and is most likely due to cheap ammo. The mid length gas port tames the felt recoil making follow up shots a thing of ease. Its just a pleasure to shoot keeping the weight centered on the rifle. The taper profile balanced the rifle weight perfectly, the barrel harmonics feel great, I was worried about barrel whip with the tapper profile but even after some mag dumps and heating things up I still got a 10rd MOA group at 100yrds with 2 flyers. Zero complaints here. I can't speak to the durability yet but it has become my favorite so far and my new go to for what's it's worth.

Sweet barrel.
