Introduction
Tired of a trigger that feels more like a chore than an enjoyable part of your shooting session? Are you aiming for tighter groups, faster follow-up shots, and an overall more satisfying experience with your Smith & Wesson M&P 15-22? If the answer is yes, then you’re in the right place. The M&P 15-22 is a fantastic rimfire rifle, beloved for its AR-style platform, affordability, and ease of use. But like many factory-equipped firearms, the stock trigger often leaves something to be desired.
That’s where drop-in triggers come in. These upgrades are designed to replace your existing trigger mechanism quickly and easily, offering a dramatic improvement in performance. They provide a cleaner break, lighter pull weight, and a shorter reset, all of which contribute to enhanced accuracy and a more pleasurable shooting experience.
This article is your comprehensive guide to the best drop-in triggers available for the S&W M&P 15-22. We’ll dive into the reasons why upgrading your trigger is a worthwhile investment, discuss the key features to look for when choosing a new trigger, review some of the top-performing options on the market, and provide you with the information needed to make an informed decision and get the most out of your .22LR rifle. Let’s transform your shooting from mediocre to magnificent.
Why Upgrade Your Trigger?
The factory trigger on the M&P 15-22, while functional, can be a limiting factor in your shooting potential. The common issues with the standard trigger often include a long, heavy pull, a mushy break, and a slow reset. These characteristics can lead to inconsistencies in shot placement and make it more difficult to achieve tight groupings.
Think about it – with a heavy trigger, you’re more likely to unintentionally move the rifle just before the shot breaks, causing a flyer. A long pull means your finger has to travel further, which can introduce wobble and make it harder to stay on target. A slow reset delays your ability to take follow-up shots, crucial in both target shooting and tactical scenarios.
Upgrading to a drop-in trigger addresses these shortcomings. You will experience:
Improved Accuracy
A lighter, crisper trigger allows for more precise control, leading to smaller groups and increased accuracy.
Faster Follow-Up Shots
A shorter reset means you can get back on target more quickly, allowing you to engage multiple targets faster or quickly reacquire a single target.
More Enjoyable Shooting Experience
A smooth, consistent trigger makes shooting more fun and less fatiguing. The enhanced feel can significantly improve your satisfaction.
Reduced Trigger Pull Weight
Lighter trigger pull weights minimize the effort required to fire a shot, which reduces muscle fatigue, and reduces the chance of disturbing your sight picture.
Crisper and More Predictable Break
A crisp break provides a clean and consistent release, allowing you to anticipate the shot and maintain better control.
Simply put, upgrading your trigger is one of the most cost-effective ways to upgrade the performance of your M&P 15-22.
Key Features to Consider When Choosing a Drop-In Trigger
Before diving into the specific trigger models, it’s essential to understand the features that separate the good from the great. Here’s what you need to consider:
Trigger Pull Weight
This is arguably the most important factor. The trigger pull weight is the force, measured in pounds, required to fire the gun. A lighter pull weight makes it easier to break a shot consistently. However, you shouldn’t go too light, or you risk accidental discharges. A common range for target shooting is between 2-4 pounds, while some shooters prefer slightly heavier pulls for defensive purposes.
Pull Length
The pull length refers to the distance your trigger finger travels before the gun fires. A shorter pull length makes it easier to maintain control and take quick follow-up shots. Shorter pulls are generally preferred for accuracy and speed.
Reset
The reset is the point at which the trigger returns forward after firing, readying the gun for the next shot. A short and positive reset is crucial for rapid follow-up shots. It allows you to quickly and efficiently reacquire your target without unnecessary delay.
Trigger Break
The trigger break is the feeling you get when the trigger releases the sear and the gun fires. A crisp and clean break is essential for accuracy. It means the trigger releases the firing pin or hammer in a predictable manner, minimizing any unwanted movement of the rifle. A “mushy” or “creepy” trigger break can negatively impact accuracy.
Installation
One of the primary benefits of drop-in triggers is their ease of installation. Look for triggers that require no gunsmithing and can be installed with basic tools. A simple installation process means you can upgrade your rifle quickly and get back to shooting.
Material and Durability
Consider the materials used in the trigger’s construction. High-quality materials, such as hardened steel and aircraft-grade aluminum, will ensure the trigger’s longevity and reliable performance. A durable trigger will withstand the rigors of regular use and last for years.
Cost
Drop-in triggers range in price, so it’s important to consider your budget. While a more expensive trigger might offer superior performance, a great trigger doesn’t necessarily have to break the bank. Set a budget and then explore triggers that fit your needs within that range.
Warranty
A manufacturer’s warranty provides peace of mind and indicates the manufacturer’s confidence in their product.
