Are these BCG'S good quality? They're a good price at msrp $130 and seem to have good specs and has a 9310 bolt. Another bcg that I'm interested in is the ALG defense bcg for around 160$. It seems to have the same specs as the odin works bcg but has a more known company standing behind it. ALG is a sister company to Giessle. Another bcg that I'm considering is the Rainier arms bcg that has a chrome silicon extractor spring and a 158 carpenter steel bolt and is "precision cut" but this one is at 170$. Am I overthinking this? Do bolts have effects on accuracy? I want to build a premiumish AR. My budget is around $1100 and I want a Nitrided bolt.
