GROVTEC MTMX3 EXTENDED MAG 12 Review

First Thoughts on the GROVTEC MTMX3 EXTENDED MAG 12

As an experienced outdoor and tactical gear specialist, I’ve seen countless accessories come and go. The GROVTEC MTMX3 EXTENDED MAG 12 immediately caught my eye due to its promise of rugged reliability and straightforward functionality. At a price point of $35.99, it presents itself as an accessible upgrade for shotgun enthusiasts.

My interest in this particular product stems from a need to improve magazine tube capacity on my Mossberg 500 for 3-gun competitions. Factory magazine tubes often limit practical use. I was looking for an extension that wouldn’t break the bank but would provide a reliable, secure fit.

Upon unboxing, the GROVTEC MTMX3 EXTENDED MAG 12 feels solid and well-machined. Its matte black finish appears durable, and the threads are clean and precisely cut. Compared to some generic extensions I’ve handled, this one immediately exudes a higher level of quality. I also considered Nordic Components and TacStar extensions, but opted for the GROVTEC due to its reputation for value and positive user reviews, hoping to get solid performance without the higher price tag.

My first impression is cautiously optimistic. It seems like a well-made, no-frills extension. I am excited to see how it performs on the range.

Real-World Testing: Putting GROVTEC MTMX3 EXTENDED MAG 12 to the Test

First Use Experience

I first tested the GROVTEC MTMX3 EXTENDED MAG 12 at my local shooting range, primarily focusing on rapid-fire drills and reload speeds. I used it on my Mossberg 500. I specifically tested the extension using both birdshot and buckshot.

The extension performed admirably in dry conditions. Loading was smooth, and there were no noticeable hang-ups or feeding issues. The increased capacity was a welcome change, allowing for longer strings of fire before needing to reload. After the first few magazines, the MTMX3 showed no signs of loosening.

However, I did experience a slight issue with a few rounds of cheaper bulk birdshot. It seemed the crimp on those rounds was slightly less uniform, causing occasional hesitation during loading. No failures occurred with quality buckshot.

Extended Use & Reliability

After several weeks of regular use, the GROVTEC MTMX3 EXTENDED MAG 12 has proven to be a reliable addition to my shotgun. I’ve put hundreds of rounds through it. It shows only minor signs of wear around the attachment point.

Durability is excellent. Despite some minor scratches from handling, the extension’s finish remains intact. Cleaning is simple. A quick wipe-down with a CLP-soaked rag keeps it functioning smoothly.

Compared to my previous experiences with lower-quality extensions that would frequently loosen or cause feeding problems, the GROVTEC is a significant improvement. It consistently outperforms expectations, providing a secure and reliable increase in magazine capacity.
