My go to for any rifle 14.5 or greater is their Full Auto standard BCG - L7D3.
For anything shorter than 14.5, I normally run the L7Q3A Full Auto Enhanced Carrier (no bolt). For the bolt- in my case when I swapped out my L7D3’s the round count was low enough I felt comfortable pulling the bolt from the L7D3 BCG and using it in the Enhanced carrier. So standard bolt with enhanced carrier. For the new builds where I’m not replacing an L7D3, I use a Sionics bolt.
Sionics sells a “bolt completion kit” that has an NP3 bolt and cam pin. Also includes a firing pin and firing pin retaining pin. Their bolt is made with Carpenter 158 steel, which is mil spec. The bolt also has improved extractor springs, so if you are a guy who upgrades the extractor springs in your bolt - that’s already done. That’s a plus.
I’ll post the links to each part, it might make it easier to check out. As a side note, while LMT usually has stock, I’ve found better deals in the FA BCG (standard) st DSG Arms and I want to say Strong Side Tactical, but may have been Tombstone Tactical... point being it won’t hurt to shop around. Just be sure your looking at the full auto version rather than semi-auto version. FA is heavier.

In my opinion, the L7Q3A + Sionics Bolt Completion Kit is a winning combo and I believe there are some reliability gains with the carrier, and I believe NP3 is a superior coating than NiB.
Let me know if you have any questions.

Reason: Added extractor spring info.
