This video reviews the Wide Open Trigger (WOT) for AR-15 platforms, highlighting its potential for high cyclic rates and the 'American RPK' concept. The host emphasizes the trigger requires finesse to avoid seizing and recommends specific components like an H2 buffer and M16 BCG for optimal performance. While acknowledging semi-auto's professional accuracy, the WOT is praised for its fun factor and collector value.
This video debunks the myth that installing an M16 bolt carrier group (BCG) into an AR-15 automatically makes it fire full-auto. It clarifies that a full-auto conversion requires specific lower receiver components like a full-auto trigger group and an auto sear, which are absent in a standard AR-15. The M16 BCG's extra lug is designed solely to interact with the auto sear.
Choosing the right Bolt Carrier Group (BCG) for your AR-15 involves understanding steel types like 8620, Carpenter 158, 9310, and S7, each offering different strength and durability. Coatings such as Phosphate, Nickel Boron (NiB), and Diamond-Like Carbon (DLC) impact friction and maintenance. Critical features include M16 vs. AR-15 profiles, proper gas key staking, and quality control like MPI testing. Enhanced designs with relief cuts and balanced components reduce wear and improve reliability.
