This video continues a series on AR-15 building mistakes, focusing on common errors often overlooked. Presenters Steve and Caleb from Brownells cover critical issues such as incorrect barrel nut torque and alignment, misuse of Dremel tools for 'fixes,' and improper gas block alignment. They also advise on keeping spare small parts, a common castle nut installation error (installing backward), and the disconnector and bolt catch spring mix-up. The content is presented with humor and expertise, aiming to educate both novice and experienced builders on achieving precision and avoiding costly errors in AR-15 assembly.
This video from Brownells Gun Tech™ provides a quick tip on identifying AR-15 trigger springs, specifically distinguishing the disconnector spring from the bolt catch spring. Host Caleb Savant explains that these springs are not interchangeable and details a key visual difference: the disconnector spring has a flared end that fits into the trigger. He emphasizes that installing the wrong spring will lead to malfunctions in either the disconnector or the bolt catch, offering a practical solution to avoid common building errors.
