This video focuses on a modification to extend a firearm's barrel to avoid National Firearms Act (NFA) regulations. The core concept revolves around the idea of "permanently attached" components. The description highlights the GUNBROS brand as a family-owned business committed to customer service and providing high-quality, battle-tested products, emphasizing Second Amendment freedoms.
This video explains the concept of a "Pinned & Welded Muzzle Device" in firearms. The presenter, Mike, discusses what this specific modification entails. The video also promotes CMMG's insider program for updates on new releases and encourages viewers to connect with CMMG on Instagram and Twitter. While the video doesn't demonstrate specific firearms or calibers, it focuses on a common firearm modification.
This video focuses on the SOTAR Secret Shopper series, specifically examining the Ruger AR556 upper receiver in Part 3 of 4. Despite audio issues preventing a reshoot, the analysis dives into several quality control and assembly issues found on the upper receiver. These include gas port measurements, cosmetic scratches, potential binding with PMags, misaligned barrel extensions, issues with barrel nut and muzzle device torque, non-concentric muzzle threads, a misaligned gas system, and under-torqued rail screws and gas block set screws. The lack of barrel dimpling and thread locker for the gas block set screws are also highlighted as concerns.
This video details a teardown and inspection of a PSA/H&R XM177 complete upper receiver, revealing significant issues with the barrel nut installation. The description highlights excessive torque (300 ft lbs) which caused the index pin to bend and gouge the receiver. The presenter also notes that PSA/H&R's representative, Mike, dismisses these findings. The presenter subsequently corrected the issues by replacing the index pin, properly lubricating and torquing the barrel nut, bedding the barrel, and using the correct jig, resulting in proper alignment of the FSB and barrel extension.
Caleb from Brownells demonstrates the proper use of the Breechtool for cleaning AR-15 style firearms. The video highlights the tool's interchangeable brush heads, hook feature for patch use, and spike for carbon removal from the bolt carrier group. It also touches upon different Breechtool variants, including the original and the Ops pack. The demonstration focuses on efficient cleaning of the star chamber and barrel extension.
This Brownells Tech Tip focuses on the innovative feed ramp design of the BRN-180 rifle chambered in .350 Legend. The video highlights how the BRN-180's single, large feed ramp, made possible by its trunnion design, overcomes the feeding challenges often associated with heavier .350 Legend bullets in AR-style platforms. This design is particularly beneficial for enhancing reliability with subsonic ammunition, offering a distinct advantage over the standard AR-15 dual feed ramp system. The content aims to educate viewers on the engineering principles behind this firearm's improved feeding performance.
This YouTube video from Shot Show 2024 features Jordan and Andrew from ARFCOM taking an in-depth look at Global Ordnance's first in-house firearm, the MONOLITH rifle. A key feature highlighted is the rifle's innovative monolithic design, where the barrel extension, muzzle device, and gas block are integrated into a single component, a collaboration with Dead Air. The video also provides links to BCM and the ARFCOM Discord server. The presentation is informative, focusing on a new firearm release at a major industry event.
This video reviews the MPA Defender, a $399 clone of the Mac-11. The content covers an unboxing, examination of various parts including the trigger and an optic mount, range testing with initial shots, a 100-yard gong test, and a discussion of a barrel extension. The creator also touches on a 'Forrest Gump' segment and slow-motion footage. The video aims to provide joy through the firearm experience and includes links to the creator's printing equipment, filament, merchandise, Patreon, gear, and a second channel.
This video description hints at a modification or accessory that increases the overall length of a "20" RPK of the homeland." The title "Man adds 4" to overall length with one simple trick" suggests a focus on firearm customization or accessories that affect the physical dimensions of the rifle. This could involve muzzle devices, barrel extensions, or stock modifications. The content likely appeals to RPK and AK platform enthusiasts interested in enhancing their firearms.
This video delves into the 'why' behind press-fit barrels in firearms. The description emphasizes that this design choice is crucial for isolating and securely fixing the barrel extension. The presenter highlights how movement or "slop" in the barrel extension can negatively impact a firearm's accuracy and bolt flight. The solution offered is the use of deliberate tolerances during manufacturing to eliminate these issues from the outset.
This video from Brownells Gun Techs debunks the myth that bedding an AR-15 barrel into the upper receiver improves accuracy. They explain that a snug fit is usually achieved by proper barrel nut torque, which compresses the receiver around the barrel extension. Bedding, typically with Loctite, is unnecessary for properly manufactured components and may indicate underlying issues with the upper receiver or barrel extension. The video suggests that if a barrel extension is loose after torquing, the solution is a new, in-spec upper receiver. They also briefly mention upper receiver lapping as an option but deem it unnecessary for high-quality uppers.
This video discusses the practice of pinning and welding muzzle devices on firearms. While the specific firearm models or calibers are not explicitly stated, the topic of muzzle devices implies a focus on rifle or carbine platforms. The description directs viewers to the creator's website for featured products, suggesting this is an informational video related to firearm modifications or accessories. The presence of links to their social media further indicates an established firearms-focused channel.
