My Buying Guides on Shotgun Shell Holder Picatinny Rail
When I first decided to get a shotgun shell holder for my Picatinny rail, I realized there were a few important factors to consider. Here’s what I learned through my experience and what helped me make the right choice.
Understanding What a Shotgun Shell Holder Picatinny Rail Is
Before buying, I made sure I knew exactly what this accessory does. A shotgun shell holder that mounts on a Picatinny rail lets you carry extra shells right on your shotgun for quick and easy access. It attaches securely to the rail system on your firearm, keeping your shells organized and within reach.
Compatibility with My Shotgun
The first thing I checked was whether the shell holder would fit my shotgun’s Picatinny rail. Not all rails are exactly the same size or configuration, so I measured my rail and read product descriptions carefully to ensure compatibility. Some holders are adjustable, which can be a bonus if you have a unique setup.
Capacity and Shell Size
I thought about how many shells I wanted to carry and what size shells my shotgun uses (like 12-gauge or 20-gauge). Some holders can carry 4 shells, others 6 or more. I chose one that matched my typical loadout without adding unnecessary bulk.
Material and Durability
Since I use my shotgun outdoors frequently, durability was a big factor. I looked for holders made from high-quality materials like aluminum or reinforced polymer. These materials resist rust, impact, and wear, which is important for reliability in the field.
Ease of Installation
I wanted something I could mount quickly without needing special tools. Many shotgun shell holders come with screws and mounts that fit standard Picatinny rails, making installation straightforward. I also appreciated designs that allowed for quick removal if needed.
Retention and Security of Shells
It was crucial that the shells stay firmly in place even when moving quickly or through rough terrain. I tested a few holders and found that those with strong elastic loops or molded slots held shells securely without making them hard to remove when I needed them.
Weight and Bulk Considerations
Since adding accessories affects the balance and weight of my shotgun, I chose a lightweight holder that didn’t add too much bulk. A slim profile helped keep my shotgun easy to handle and carry.
Price vs. Quality
I balanced my budget with quality. While cheaper options are tempting, I found that investing a little more in a reliable holder paid off in terms of durability and functionality.
Additional Features
Some holders come with extra features like extra mounting points, compatibility with other rail systems, or even camouflage finishes. I considered these based on my specific needs and environment.
Final Thoughts
Buying a shotgun shell holder for my Picatinny rail improved my shooting experience by keeping shells accessible and organized. By focusing on compatibility, capacity, durability, and ease of use, I found a product that fits my needs perfectly. I recommend anyone looking to buy one to carefully assess these factors so you can get the best match for your setup.
