New build, do I have the correct parts

[GrantB]

Building a 300 blkout SBR and want to know if I'm using the correct parts for reliable operation.

Saturn 10.5" barrel with pistol length gas system. .110" gas port, H carbine buffer, 10 3/4" spring with 38 coils and .072 wire size, standard gas block, rock river BCG, I will be shooting both sub and supers out of it without suppressor (at least for now)

Thinking of AA1680 and 200+ grain for subs and H110 and 125ish for the suppers.

Does anybody see a problem with this plan.

run an H2 buffer with a pistol gas SBR. It will run with an H, but the H2 is the recommended.
