Edwin Sarkissian, a high-profile firearms content creator, experimentally tests the ballistic resistance of a 7075 aluminum plate against various firearms. He demonstrates a custom 6-barrel Gatling rig with Gilboa Snake AR-15s firing 5.56x45mm NATO, an H&K MP7 in 4.6x30mm, and a full-auto converted .45 ACP 1911. The tests reveal the aluminum's significant resistance, with none of the calibers achieving full penetration, though deep craters were formed.

This guide details a practical durability test for the GOWUTAR GP-6 Red Dot Sight, focusing on zero retention after significant physical stress. The test involves confirming zero, impacting the optic against a vehicle, and re-confirming zero. The video demonstrates the effectiveness of the GP-6's robust construction, including its 7075 aluminum body and IPX7 rating, in maintaining zero under harsh conditions, as assessed by an experienced instructor.

This video provides an in-depth look at the GOWUTAR GP-9 red dot optic, highlighting its new color variants and a significant deal alert. The presenter, with experienced authority, details its features including shake-awake technology, a 6 MOA red dot, RMR footprint, top-load battery, and durable 7075 aluminum construction. The optic is presented as a high-value, duty-grade option that competes favorably with more expensive alternatives, especially when factoring in available discounts.

This guide details the installation and a rigorous durability test of the Gowutar EP-20 enclosed red/green dot sight, featuring an ACRO footprint. The video demonstrates its mounting system, shake-awake technology, and impressive resilience through a 'torture test' involving impacts on a car hood, with the optic maintaining zero throughout. Instruction is provided by an experienced individual knowledgeable in optic footprints and materials.

This video features Edwin Sarkissian, an experienced firearms instructor, conducting a unique bullet penetration test. He uses 12 Ozark Trail 12-inch cast iron skillets to determine how many rounds from various calibers and firearms, including 9mm, .45 ACP, 500 S&W Magnum, 7.62x39mm, 5.56mm, 5.7x28mm, and 12 Gauge slugs, can penetrate the cookware. The results offer practical insights into the ballistic performance of different ammunition types against a common household item.

This video from Edwin Sarkissian provides an expert-level demonstration of the Serbu BFG-50A rifle's capability against a railroad track. Sarkissian, a high-level firearms enthusiast, showcases the .50 BMG caliber's power with various ammunition types, including the specialized Raufoss Mk 211 Mod 0, highlighting its penetration through thick steel. The content offers valuable insights into terminal ballistics and the performance of heavy caliber rounds.

This video demonstrates a unique application of the X Products Can Cannon, a gas-operated launcher compatible with AR-15/M16 lowers, to launch an M67-style fragmentation grenade using .223 Blanks. Expert experimentalist Edwin Sarkissian showcases the process of loading and firing the device towards a frozen lake, highlighting the launcher's ability to hold the grenade's spoon in place until firing. The demonstration results in a significant explosion and ice shatter upon impact.

This guide details a ballistic test comparing a .50 Cal Spotter round against a 1.25-inch thick bulletproof glass panel using a Serbu BFG-50A rifle. The test, conducted by firearms enthusiast Edwin Sarkissian, demonstrates the significant destructive potential of specialized .50 BMG ammunition, highlighting differences in impact effects between incendiary spotter rounds and standard FMJ rounds. The expert-level demonstration emphasizes the importance of understanding ammunition types and their performance against protective materials.
