Exactly what you didn't know you needed!!!I purchased the 4.75" BBSS 300BLK barrel with 5R rifling package that includes the micro gas tube and KAK's adjustable buffer kit. Besides the barrel by itself being $190, and the micro gas tube being $18, you save $8, which is almost the shipping costs. THEN, last but certainly not least, it comes with KAK'S AR15 adjustable buffer kit, which is almost a $50 value for pretty much nothing. This is a steal of a deal. Though I haven't had to chance to test fire the new barrel, I have zero doubt it'll work flawlessly like it's little brother in 5.56, I'll update my review as soon as I'm able to test it out.
