This video reviews the Griffin Armament Optimus Micro Suppressor, highlighting its durability and versatility. The presenter, an experienced firearms instructor, emphasizes its robust 17-4 stainless steel construction and heat-treated baffles, making it capable of handling limited rounds of 5.56 NATO in addition to its primary .22LR and rimfire applications. The suppressor's removable baffle stack and taper mount system are key features discussed for ease of cleaning and enhanced performance with higher pressure rounds.

This guide details the process of testing a 5.56mm suppressor (Griffin Armament Optimus Micro) on a Palmetto State Armory (PSA) Rock pistol chambered in 5.7x28mm, specifically without using a booster. The demonstration focuses on verifying cycling reliability with this non-standard setup, highlighting the importance of suppressor pressure ratings and the potential for successful operation in certain configurations. The video emphasizes an experimental approach to firearm and accessory compatibility.

This video features a critique of a home defense AR-15 build by former Navy SEAL Jeff Gonzales. Key takeaways include the importance of a suppressor for indoor use, the critique of an overly complex sling, and recommendations for reliable optics. The discussion highlights the trade-offs of short-barreled rifles (SBRs) for home defense and emphasizes practical gear selection over complexity.
