Description
The Howa single-shot block for 350 Legend magazine transforms your Howa 1500 Mini Action into a single-shot rifle without any gunsmithing or permanent modifications. Just drop it in where your standard magazine goes, and you're ready to run one round at a time.
What Makes the Howa Single Shot Block Ideal for 350 Legend
This polycarbonate block is engineered specifically for the Howa Mini Action and the 350 Legend cartridge. The short action length is critical here, and Howa got it right with a compact 3.65-inch profile that fits flush with your stock. The matte black finish blends in with your rifle and won't reflect light during hunting situations. It's ambidextrous, so it works for both left and right-hand shooters without any hassle.
When You'll Want Single-Shot Operation
There are plenty of practical reasons to run single-shot. If you're testing new reloads and want absolute consistency between shots without mag changes affecting your point of impact, a single-shot block gives you that control. Range days become more deliberate and focused too. Some folks use it on hunting trips in areas with specific requirements, where it's the way to go. On top of that, it forces you to be deliberate about your shots, which never hurts your technique.
Installation and Reliability
There's nothing to install beyond dropping this block into your magazine well. It seats and locks just like your regular magazine, meaning zero compatibility headaches with your Howa 1500. The polycarbonate construction is tough enough for field use without being overly heavy. You're looking at a solid, no-frills component that does one job well.

Frequently Asked Questions
Does this single shot block require gunsmithing to install?
No. This block installs without any modifications to your Howa 1500 Mini. It simply replaces your standard magazine by dropping into the magazine well and locking in place like a regular magazine would. No gunsmithing, drilling, or tools required.
Will the single shot block work with my current 350 Legend ammunition?
Yes, it feeds standard 350 Legend cartridges smoothly. The block's feed ramp is designed to guide your round reliably into the chamber. Whether you're using factory ammunition or handloads, it handles them the same way.
Can this block be used for load development and testing?
Absolutely. This is one of the most practical uses for a single-shot block. When you're working up loads, having one round per cycle removes magazine-related variables and gives you more consistent, repeatable results between shots for better load testing data.
Is the block ambidextrous for left and right-handed shooters?
Yes, it's designed as ambidextrous, so it works equally well whether you shoot from your right or left shoulder without any adjustments needed.
