Key recommendations include upgrading the bolt carrier group on standard models and prioritizing FN Cold Hammer Forge barrels for durability.

This video tests the Vector Industries bolt for AR-15 platforms, claiming to improve rifle timing and reduce gas system pressure. The presenter, drawing on knowledge from engineers and armorers, conducts a series of tests comparing the Vector bolt to factory bolts in various rifles.

This review of the Palmetto State Armory Gary Gordon-inspired M16A2 Retro Carbine 15 highlights its strengths as a budget-friendly, compact retro-style rifle, particularly suited as a truck gun.
