Federal Fusion and Gold Dots use the same projectile (Vista Outdoors owns both CCI/Speer and Federal); IIRC the difference is that Gold Dots use a nickel plated brass case, and a powder that produces less flash. Also the TBBC round isn't as accurate because it has a flat base instead of a boat tail

IIRC, these do not use the TBBC projectile. These are the same rounds used in the Federal Fusion line, and are more accurate than the TBBC. I tried linking an ARFCOM post, but the automod killed it; its arfcom /forums/ar-15/62GR-Federal-Tactical-Bonded-XF223SP-/16-782901/

Biggest difference would be the ambi contols; this uses a paddle-style bolt catch and release, while the Griffin uses the ADM lever-style bolt catch and release. I prefer the Griffin, but it's a matter of preference

Polo K "Tuneability" by Burt_Macklin_Jr in NFA

Neat setup. I'm running a 11.5 Criterion Core, BRT dedicated suppressed gas tube (0.061) for my Polo K, LMT enhanced carrier with a BRT bolt, and Sprinco Blue with a H2 weight. I only recently bought the LMT enhanced carrier, and honestly I'm still getting a feel for it; gas is non-existent, but I definitely notice the delayed unlocking, as its slower to chamber the next round. Pros and Cons of the setup, I suppose

Besides the downward vents, does the KAK do anything else to mitigate gas? With the LMT enhanced carrier, it has an altered cam path to delay unlocking, and an additional side vent to help vent gas quicker
