Ruger MAG 20-300 BO 20RD – 300 AAC Blackout Caliber, 20 Rounds, OEM Origin, Ruger Model Review

The Ruger MAG 20-300 BO 20RD – 300 AAC Blackout Caliber, 20 Rounds, OEM Origin, Ruger Model Made a Bold First Impression

The Ruger MAG 20-300 BO 20RD – 300 AAC Blackout Caliber, 20 Rounds, OEM Origin, Ruger Model promises reliable feeding for your Ruger Mini-14 chambered in the increasingly popular 300 AAC Blackout. With a 20-round capacity and an OEM Origin, this magazine suggests a factory-quality build. The promise of reliable feeding and a higher capacity than some standard options immediately piqued my interest, especially given the sometimes finicky nature of the 300 Blackout cartridge in AR platforms and other magazine-fed rifles.

I was specifically looking for a reliable magazine to run subsonic rounds through my suppressed 300 Blackout Mini-14 build. I’d been plagued by feeding issues with aftermarket magazines, and the promise of an OEM magazine from Ruger seemed like a potential solution. My initial unboxing was…underwhelming. The magazine arrived in standard Ruger packaging. The black finish looked durable enough, but the overall feel was lighter than I anticipated, bringing questions about longevity and build quality quickly to the forefront of my mind.

I had previously experimented with Lancer L5AWM magazines and Magpul PMAGs modified for 300 Blackout. Both offered improved reliability over the cheaper, no-name brands I had tried. The Ruger magazine appealed to me due to its OEM status and the hope that it would provide a perfect fit and flawless function with my Mini-14. I was initially cautiously optimistic, hoping the Ruger name meant guaranteed compatibility. However, the lightness of the magazine and the user feedback I had seen planted some seeds of doubt from the get-go.

Real-World Testing: Putting Ruger MAG 20-300 BO 20RD – 300 AAC Blackout Caliber, 20 Rounds, OEM Origin, Ruger Model to the Test

First Use Experience

My initial testing took place at an outdoor range. The weather was dry and sunny, ideal conditions for testing. Unfortunately, the Ruger MAG 20-300 BO failed spectacularly right out of the gate. I couldn’t even insert the magazine into my 300 Blackout Mini-14.

The magazine simply would not lock into place, no matter how much force I applied. This was a major red flag, indicating a serious fitment issue. I was immediately frustrated and deeply disappointed.

Extended Use & Reliability

Since the magazine wouldn’t even fit in the rifle, extended use and reliability testing were impossible. I attempted to diagnose the issue further by comparing the Ruger magazine to a known compatible magazine. The differences in the locking lug and overall dimensions were slight but enough to prevent proper insertion. There was no way to even test durability or if the magazine would feed reliably, as it would not seat in the rifle.

Maintenance was also a non-issue, since I couldn’t even use the magazine. This stands in stark contrast to my previous experiences with Lancer and Magpul magazines, which have proven to be incredibly reliable and easy to maintain.

Breaking Down the Features of Ruger MAG 20-300 BO 20RD – 300 AAC Blackout Caliber, 20 Rounds, OEM Origin, Ruger Model

Specifications

The Ruger MAG 20-300 BO 20RD – 300 AAC Blackout Caliber, 20 Rounds, OEM Origin, Ruger Model is specified to be a 20-round magazine chambered for the 300 AAC Blackout cartridge. It features a black finish, and is supposedly an OEM magazine manufactured by Ruger. The intended model fit is for the Ruger Mini-14 platform in 300 AAC Blackout.

These specifications should translate to reliable feeding in the Ruger Mini-14, a higher capacity than standard 10-round magazines, and the durability expected from an OEM product. Unfortunately, the key specification of proper fitment was not met in my experience.

Performance & Functionality

Based on my experience, the Ruger MAG 20-300 BO magazine failed to perform its primary function: fitting and locking into the designated firearm. This complete failure overshadows any potential positive attributes related to feeding reliability or cartridge retention. The design flaw renders it unusable, failing to meet even the most basic expectations. The magazine’s only function was to inspire frustration.

Design & Ergonomics

The magazine’s design appears outwardly similar to other Mini-14 magazines, and the black finish is aesthetically pleasing. However, the fitment issues negate any positive impressions regarding design or ergonomics. The magazine’s failure to seat properly makes any assessment of comfort or usability irrelevant. The construction and materials may be quality. However, the dimensions are not what they should be for proper fitment.

Durability & Maintenance

Durability and maintenance are irrelevant considerations given the magazine’s inability to function in the intended rifle. It is impossible to assess the magazine’s long-term durability or ease of maintenance when it cannot be used.

Accessories and Customization Options

There are no accessories or customization options applicable to this magazine, given its fundamental inability to function. The only potential modification would involve filing or grinding down parts of the magazine body to force a fit, which is not recommended and could further compromise its structural integrity.

Who Should Buy Ruger MAG 20-300 BO 20RD – 300 AAC Blackout Caliber, 20 Rounds, OEM Origin, Ruger Model?

Nobody should buy this product until Ruger addresses the fitment issues. Based on my experience, this magazine is incompatible with the Ruger Mini-14 in 300 AAC Blackout.

Anyone seeking a reliable magazine for their 300 Blackout Mini-14 should consider alternative options and thoroughly research compatibility before purchasing. Must-have modifications would involve extensive modification that the user would have to perform themselves, something not recommended.

Conclusion on Ruger MAG 20-300 BO 20RD – 300 AAC Blackout Caliber, 20 Rounds, OEM Origin, Ruger Model

The Ruger MAG 20-300 BO 20RD – 300 AAC Blackout Caliber, 20 Rounds, OEM Origin, Ruger Model is a complete disappointment. The primary function of a magazine is to fit and feed ammunition reliably, and this product fails miserably on both counts. The price of $27.99 is entirely unjustified, as the magazine is essentially a useless piece of plastic and metal.

I would not recommend this product to anyone. Seek alternative magazine options for your 300 Blackout Mini-14. Avoid this product until Ruger acknowledges and resolves the documented fitment issues.
