Let’s Talk About Presma AR-15 Lower Vise Block
The Presma AR-15 Lower Vise Block is a simple but essential tool for any AR-15 owner who likes to maintain, repair, or assemble their rifle. Manufactured by Presma, this inexpensive polymer block allows you to securely mount your lower receiver in a vise, freeing up your hands and preventing damage during various operations.
I’ve been building and maintaining AR-15s for over a decade, and I’ve seen firsthand the damage that can occur when trying to work on a lower receiver without proper support. I needed a reliable and affordable vise block that wouldn’t scratch or mar the finish of my lowers.
Upon receiving the Presma AR-15 Lower Vise Block, I was immediately impressed by its solid feel. The polymer construction feels robust and capable of withstanding the clamping force of a vise. It’s certainly more compact and lighter than some of the metal alternatives I’ve seen.
Compared to some of the more elaborate aluminum vise blocks on the market, the Presma block is undeniably simpler. I also considered the Magpul BEV Block and the Wheeler Engineering Delta Series AR Lower Vise Block, but I wanted something basic and budget-friendly for less frequent tasks. The Presma block’s price point made it an easy decision for my needs.
Initially, I was a little skeptical about the polymer construction, wondering if it would be durable enough. But the price was right, and the design seemed practical, so I was eager to give the Presma AR-15 Lower Vise Block a try.
Real-World Testing: Putting Presma AR-15 Lower Vise Block to the Test
First Use Experience
I first tested the Presma AR-15 Lower Vise Block while installing a new trigger in one of my AR-15 builds. I used it in my garage workshop, securing it in a standard bench vise.
The block performed admirably, holding the lower receiver securely while I hammered in the trigger pins. There was no slippage or movement, even with moderate force applied. The block’s angled design was surprisingly helpful for accessing hard-to-reach areas around the trigger assembly.
There were no surprises during the first use – the Presma AR-15 Lower Vise Block worked exactly as advertised. It provided a stable platform for working on the lower receiver, making the trigger installation process much easier and safer.
Extended Use & Reliability
After several months of use, the Presma AR-15 Lower Vise Block has held up remarkably well. I’ve used it for various tasks, including installing new buffer tubes, replacing pistol grips, and even diagnosing a pesky magazine catch issue.
The polymer material shows no signs of cracking or deformation, despite being subjected to repeated clamping in the vise. Cleaning is a breeze – a simple wipe down with a cloth is usually all it takes.
Compared to my previous method of propping up the lower receiver with makeshift supports, the Presma AR-15 Lower Vise Block is a game-changer. It provides a far more secure and stable platform, saving time and reducing the risk of damage. The block greatly exceeded my expectations.
