Why I Believe the Best Sig Sauer M400 Accessories are Necessary

As a long-time owner and user of the Sig Sauer M400, I have come to understand the importance of having the right accessories for this rifle. While the M400 is a reliable and high-performing firearm on its own, adding the right accessories can greatly enhance its functionality and versatility.

One of the main reasons why I believe accessories are necessary for the M400 is because they allow for customization. Every shooter has different preferences and needs, and having a variety of accessories to choose from allows us to tailor our rifle to fit our individual shooting style. Whether it’s a different grip or stock, a new optic, or an extended magazine, these accessories can greatly improve our shooting experience.

Furthermore, some accessories can also improve the overall performance of the M400. For example, adding a muzzle brake or compensator can reduce recoil and improve accuracy, while a bipod or foregrip can provide better stability for precision shooting. These enhancements not only make shooting more enjoyable but also make us more effective shooters.

Additionally, having quality accessories for our M400 can also increase its durability and longevity. By investing in high-quality parts and upgrades, we can ensure that our rifle will

My Buying Guide on ‘Best Sig Sauer M400 Accessories’

As an avid shooter and owner of a Sig Sauer M400, I have spent a lot of time researching and trying out various accessories for my rifle. Whether you are a beginner or a seasoned shooter, having the right accessories can enhance your shooting experience with the Sig Sauer M400. In this buying guide, I will share my top recommendations for the best Sig Sauer M400 accessories.

Optics

One of the first accessories I invested in for my Sig Sauer M400 was a good quality optic. The rifle comes with a standard A2 front sight post and flip-up rear sight, but adding an optic can greatly improve your accuracy and target acquisition speed.

My top pick for optics is the Trijicon ACOG (Advanced Combat Optical Gunsight). It offers a fixed 4x magnification and has an illuminated reticle that is perfect for both close-quarters shooting and long-range shots. The rugged construction of this optic makes it durable and able to withstand harsh conditions.

For those on a budget, I would recommend the Vortex Optics Strikefire II Red Dot Sight. It offers unlimited eye relief, 1x magnification, and multiple brightness settings for different lighting conditions. It also has a parallax-free design, making it ideal for quick target acquisition.

Handguard

The standard handguard on the Sig Sauer M400 can be quite uncomfortable to grip and does not offer much customization. Upgrading to a new handguard can greatly enhance your shooting experience.

My personal favorite is the Magpul MOE SL Handguard. It offers M-LOK attachment slots for mounting accessories such as lights or grips. The slim profile of this handguard makes it comfortable to grip while still providing enough space for your hand placement.

Another great option is the Midwest Industries Two-Piece Drop-In Handguard. It offers a lightweight and sturdy design with plenty of rail space for mounting accessories. This handguard also allows you to maintain your front sight post if you prefer to use iron sights.

Trigger

Upgrading the trigger on your Sig Sauer M400 can greatly improve its accuracy and overall performance. The standard trigger can feel gritty and heavy, which can affect your shooting experience.

My top pick is the Geissele SSA-E Trigger. It has a crisp break with minimal take-up and reset, making it ideal for precision shooting. This trigger also has adjustable pull weight options ranging from 2.5 to 4 lbs.

For those on a budget, I would recommend the ALG Defense Advanced Combat Trigger (ACT). It offers similar features to the Geissele SSA-E at a more affordable price point.

Magazine

Having reliable magazines is crucial when shooting any rifle, including the Sig Sauer M400. While the rifle comes with one 30-round magazine, having extra magazines can save you time during reloads.

My go-to choice is the Magpul PMAG Gen M3 Magazine. They are lightweight yet durable and have anti-tilt followers that prevent jamming or feeding issues. These magazines also have large capacity windows that make it easy to check how many rounds are left.

Another great option is the Lancer Systems L5AWM Magazine. These magazines have steel feed lips that provide smooth feeding without compromising durability. They also have translucent bodies that allow you to see how many rounds are left without counting them manually.

Conclusion

Investing in these accessories will not only enhance your shooting experience but also improve your rifle’s performance and functionality overall. Whether you are looking for better optics, improved ergonomics with an upgraded handguard, smoother trigger pull or reliable magazines, these recommendations are sure to meet your needs as they have met mine with my Sig Sauer M400 rifle.
