This video features the RN-50 Barrel Test Gun, a custom firearm built from a modified RN-50 to facilitate shop-made pistol barrel testing. The creator also highlights the Olight Osight red dot sight, praising its quality and affordability. Additionally, a recommendation is made for Computer Quest, LLC, an IT services company, for their excellent work.

This video details the repair process for a broken lug on a Mark Serbu RN-50 rifle. Lead Firearms Instructor and SEO Strategist Mark Serbu walks through the steps of removing the barrel, welding the lug back on, and refinishing the receiver with parkerizing. The repair is demonstrated to be successful through test firing, highlighting the importance of proper gunsmithing techniques for firearm longevity and safety.

This YouTube video showcases custom muzzle brake engraving for an RN-50 rifle. The creator explains that they rarely offer engraving due to time constraints and the difficulty of machining the brake face after a design change. However, they have now adopted laser engraving, which simplifies the process. The engraving was done at a customer's request, and the creator humorously admits to potentially forgetting about the order due to its age, which was from over a year ago.

This expert guide, presented by Serbu Firearms owner Mark Serbu, details the legal classification and ballistics of the compact Micro 50 BMG. It covers the rationale behind its SBR registration under the NFA, potential legal pitfalls related to ammunition bans, and impressive ballistics achieved with its short barrel. The guide also touches on the practical aspects of its intense muzzle blast and visual impact.

This video showcases the unique Serbu 50 BMG Micro rifles, featuring 10-inch barrels and a break-action design. The creator demonstrates firing two simultaneously, highlighting the extreme recoil and shockwave generated by the .50 BMG caliber. The review emphasizes the custom build aspect and the intense physical experience of handling these powerful, compact firearms.

This video showcases the aftermath of an RN-50 firearm that was subjected to C4 explosives. The creator's friend, who assisted in the previous comparison video, sent back the destroyed remains of the RN-50. Viewers are invited to observe the "interesting" fragments and the altered appearance of the barrel, which, due to the explosive force, now visually exhibits crystalline and rock-like structures, contrasting with its typical perception as a uniform steel material. A drinking game is playfully suggested for every mention of the word "interesting."

This video compares the "RN 50" and "C4" in a somewhat unscientific manner, reminiscent of Edwin Sarkissian's style. The creator discusses observed phenomena, particularly refuting the idea that a .50 BMG round could be responsible for a specific accident due to the distinct damage patterns compared to high explosives. The video offers a quick look at interesting aspects and promises a follow-up installment.

This guide details the process of converting a Mark Serbu RN 50 rifle from .50 BMG to 6.5x55 Swedish caliber. It involves machining a custom adapter bushing and installing a new barrel compatible with Savage 10/110 series actions. The process is explained by Mark Serbu, a recognized gun designer, highlighting the technical steps and considerations for such a modification.

This analysis from Mark Serbu, owner and lead designer of Serbu Firearms, details the catastrophic failure of the RN-50. The primary cause identified is the use of fast-burning pistol powder instead of the appropriate slow-burning .50 BMG rifle powder. Serbu uses ballistics software to illustrate how incorrect powder choice leads to extreme pressure spikes far exceeding safe limits, emphasizing the difference between failsafe design and absolute fail-proof protection against misuse.

This entry synthesizes expert analysis from Brandon Herrera and Scott of Kentucky Ballistics on firearm failures and ammunition. It covers the examination of catastrophic failures in .50 caliber rifles, the identification of overpressure indicators like 'tramp stamps' on bolt faces, and the properties of Tula 7.62x39mm ammunition. The content also touches upon the political implications of arming civilians and the risks associated with testing experimental firearms.

This analysis, presented by firearm designer Mark Serbu, debunks the common theory that the RN-50 explosion was solely due to case head separation. Serbu meticulously explains case head separation using visual examples and contrasts the RN-50's fixed headspace and internal support system with the M2 Machine Gun's critical headspace requirements. The expert concludes that separation is a symptom, not the cause, and hints at other potential failure points like ammunition or venting issues in future segments.

This video provides an expert-level analysis of a catastrophic failure of the Serbu RN-50 rifle, presented by the firearm's designer, Mark Serbu. The examination focuses on the severe damage to the receiver, breech cap, and barrel assembly, offering insights into potential failure points and the effects of extreme forces. The analysis also touches upon the ammunition used, specifically SLAP rounds, and their potential role in the incident.
