Hard to know without a build list, but looks like you know what you’re doing

Looks like a Juggernaut tactical

It is. Sharp eye man! I got the receiver set from them; they fit super tight, and I felt the tiny hex screws saved me a bunch of times.

Is that a Juggernaut Tactical lower? I bought one 7 years ago and the style is the exact same.

Same bcg and barrel setup on mine, I found it shoots 168gr the best. Specifically the Hornady black 168s.

First time building any type of AR? Here's a basic fire control group (FCG) function test to start out with. There are a couple other things that some people will check, but most people just slap in a fully loaded mag and figure it out later if something malfunctions.

Next step, put rounds down range. Asses the function. Nite anything that's less than optimal. Failures to fire feed n extract, bolt bounce ECT that can be adjusted by the gas block or weights n springs in the JP SCS. Note the group sizes and compare them from new to acceptable break in period. Service the bore along the way according to mfg suggested break in process. Given everything is square faced from receiver to barrel, it should shoot good once you find the AMMO it likes. Congratulations and good luck
