The M16A1 rifle is best suited for M193 55-grain ammunition due to its 1:12 twist rate. M855 62-grain ammunition, designed for faster 1:7 twist rates found in M16A2 and M4s, is not ideal for the M16A1 as it may not stabilize properly. Understanding ammunition and rifle specifications is crucial for optimal performance and safety.

This video details an accuracy test of the IWI Tavor X95 bullpup rifle at 100 yards, evaluating four different ammunition types: M193 55gr FMJ, M855 62gr steel core, Hornady 75gr HPBT Superformance Match, and a 60gr V-MAX handload. The M193 ammunition yielded the best group size, suggesting the X95 may favor lighter bullets. The presenter notes the rifle's inherent limitations as a bullpup without a free-floated barrel but concludes it's an accurate battle rifle.

This video clarifies the differences between M193 Ball and SS109 (Green Tip) ammunition, focusing on their compatibility with different barrel twist rates. It explains that M193 (55 grains) is optimized for a 1:12 twist, while SS109 (62 grains with a steel penetrator) requires a faster 1:7 twist for optimal stabilization and accuracy. The instructor debunks the myth that Green Tip ammunition damages chrome-lined barrels, stating that improper ammunition selection for a given twist rate leads to inaccuracy, not barrel damage.

This video demonstrates the principles of designated marksman rifle (DMR) marksmanship, focusing on engaging targets at extended ranges (100-500 meters). It covers proper scope usage, trigger control techniques like the 'squeeze' and 'empty lung' method for breath holding, and the importance of consistency for accurate fire. The instruction emphasizes achieving hits at distances up to half a kilometer using standard ammunition.

This video tests RMA Level IV armor plates against various rifle rounds, including .30-06 M2 AP and 5.56 M855A1/M855, following news of the armor losing its NIJ certification. The testing demonstrates that the armor successfully stops multiple rounds, including M2 AP, even after its ceramic structure is compromised, suggesting it exceeds its certification requirements. The presenter, a firearms instructor, expresses continued confidence in RMA armor based on these results.

This YouTube video features a test and evaluation of M855 Ball and M193 Ball ammunition fired through a 1:12 twist barrel AR-15 type rifle. The creator aims to determine the accuracy of these military ball rounds on a target. The video also includes a contest where viewers are encouraged to share the video on social media for a chance to win, with the winner announced the following day. The description is in Tagalog.

This guide details the experimental procedure used to test the safety mechanism of a Blank Firing Attachment (BFA) on an AR-15/M16 style rifle. The test involves remotely firing a live round through a BFA to observe if it detaches safely, preventing injury. The video demonstrates that the BFA successfully sheared off without damaging the rifle, confirming its safety design. A follow-up live fire test ensures the rifle's continued functionality.
