Videos tagged with Sear Adjustment

This video from Desk Pop demonstrates a compatibility test for the C.A.R.L. three-round limiter, primarily with AR-15 platforms and their variants. The presenter, exhibiting expert-level knowledge, details how the limiter's functionality is dependent on proper hammer reset and cam rotation, often requiring specific trigger group components like a milspec trigger. Crucially, the video provides a detailed modification guide for the 'third sear' to ensure correct engagement with the cam, addressing issues that lead to more than a three-round burst. It also explores compatibility with various platforms including AR-9s, .300 Blackout, and .22LR AR-15s, highlighting the importance of back pressure from suppressors and clean firearm operation.

Master Gunsmith Jack Rowe provides advanced insights into trigger pull adjustments, focusing on the sear. He advises against altering the hammer bent unless necessary and details the severe mechanical consequences of shortening the sear nose, including reduced striker travel and potential misfires. Rowe demonstrates a precise gunsmithing technique for lengthening an undersized sear by heating and hammering the metal, emphasizing caution and expertise.
