This video details a buildout for the PSA Olcan, a bullpup configuration utilizing a Jackal upper receiver. It covers mounting a Holosun AEMS optic with a Scalarworks mount for proper height, adding grip enhancements with B5 M-Lok covers, and installing a Magpul barricade stop for hand safety. The build also features a SilencerCo Omega 360 suppressor and highlights the importance of the adjustable gas block for tuning performance, especially with suppressed use.

This review of the Palmetto State Armory Olcan bullpup chassis, designed to accept AR-compatible uppers like the Jackal, highlights significant design compromises. The reviewer, identifying as an expert on bullpups, details issues inherent to chassis systems, such as optic mounting challenges due to raised comb height and the need for specific optic riser heights (around 1.93"). Specific criticisms are leveled at the Olcan and Jackal combination, including a poor trigger, weight inefficiency, and severe gassing issues, particularly when suppressed, making it one of the most unpleasant firearms the reviewer has shot. The review suggests the product feels unfinished, with potential improvements like a longer handguard or a dedicated 16-inch barrel Jackal upper being unlikely.

This guide details the process of converting the Colt LE-901 modular rifle from its native caliber to function with 5.56 NATO uppers. It involves using a specific magazine well adapter and front pin to ensure compatibility with standard AR-15 components and magazines, allowing for seamless caliber changes.

This video showcases the installation of a BS Squirts drop-in kit for an AK-47 FRT trigger. The presenter, Jordan of Poor Boy Arms, highlights that the kit was a direct fit with no modification required. Due to a lack of ammunition, a live-fire demonstration was not possible, but a function check confirmed the trigger's operation.

This video directly compares the fire rate of a Fightlite beltfed AR-15 upper receiver against an M249 SAW machine gun. The test involved firing a 15-round burst from each weapon to measure their cyclic rates. The Fightlite upper demonstrated a significantly faster fire rate than the M249 SAW.

This video from Civilian Tactical explores the common claim that a .50 BMG round can be lethal even if it misses its target by a small margin. Using a ballistic dummy head, cardboard proximity sensors, and a cinder block backstop, the test demonstrates the extreme power of the .50 BMG. The host, exhibiting high authority and expertise, uses a Big Kahuna Firearms Raptor .50 BMG upper receiver on an AR-15 platform to conduct the experiment, concluding that a near miss is not lethal.

This video reviews a pre-production beta sample of the Lima 6 belt-fed conversion for the AR-15 platform. The instructor highlights its potential to make belt-fed firearms more accessible due to a projected competitive price point compared to existing high-end options like the Fightlight MCR. Key features discussed include its Direct Gas Impingement system, reciprocating charging handle, and compatibility with standard AR-15 lowers with a modified bolt stop.

This guide details the installation and initial function check of the BoreBuddy .22LR upper receiver, a component designed for AR-15 platforms. The video emphasizes its utility for training with triggers like the FRT or Super Safety, offering significant cost savings over centerfire ammunition. The host, demonstrating high expertise, highlights the importance of lubrication for .22LR reliability and showcases the system's accuracy and AR-15-like manual of arms, including a bolt lock feature.

This video details how to build a functional 50 BMG rifle on a budget, primarily by utilizing an AR-15 lower receiver with a specialized Big Kahuna 50 BMG upper. The build can be achieved for approximately $1,800, excluding optics and bipod, making it significantly more accessible than traditional high-end 50 BMG platforms. Key steps involve replacing the AR-15 hammer with an upgraded component to accommodate the larger caliber and ensuring compatibility with the AR-15 lower.

This video explains how a CMMG .22LR Bolt Carrier Group (BCG) functions within a 5.56 chambered AR-15 rifle. It highlights the use of a chamber adapter and how the .22LR bullet glides through the 5.56 barrel's rifling due to similar projectile diameters. The explanation clarifies why this conversion is specific to 5.56/.223 barrels and not compatible with larger calibers like 300 Blackout.

This review focuses on the Sig MCX Spear LT 16-inch conversion kit, highlighting its ability to run on any M4 lower receiver. The presenter details the kit's components, including the upper receiver, handguard, and included BCG and charging handle. Key features like the short-stroke gas piston system, adjustable gas block, and quick-change barrel system are discussed, along with performance observations and comparisons to other firearms.

This video demonstrates the Raptor 50, a bolt-action upper receiver for the AR-15 platform chambered in .50 BMG. It highlights the cost-effectiveness of this conversion compared to dedicated .50 BMG rifles and shows a test of its power by firing at a bowling ball.
