Bushmaster ACR Full Review: Performance and Reliability

Introduction

The Bushmaster Adaptive Combat Rifle (ACR) was designed with modularity and performance in mind, aiming to offer unparalleled adaptability for tactical and civilian users alike. Originally envisioned by Magpul as the Masada, the ACR was brought to life by Bushmaster with the promise of being the ultimate customizable rifle. In this review, we will break down the rifle’s performance, reliability, and customization options, assessing whether the ACR meets its lofty goals of versatility and power.

Performance

Accuracy and Handling

The ACR is recognized for its free-floating barrel, which provides excellent accuracy at various ranges. The rifle’s quick-change barrel system allows users to easily swap out barrels to suit their specific needs, making it highly versatile for different shooting situations. The ACR is available in multiple calibers, including 5.56 NATO, .300 Blackout, 6.8 SPC, and .450 Bushmaster, making it adaptable for different operational roles, from close-quarters combat to long-range precision shooting​.

The gas piston system adds to the rifle’s smooth operation, minimizing recoil and allowing for rapid follow-up shots. However, some users find the ACR slightly bulkier than other rifles in its class, which may impact handling in fast-paced scenarios.

Pros:

• Exceptional accuracy due to free-floating barrel
• Smooth recoil and easy handling
• Adaptable to various calibers

Cons:

• Heavier than comparable rifles, affecting quick target acquisition

Reliability

The ACR performs well in reliability tests, especially due to its gas piston system, which reduces fouling and makes the rifle easier to maintain in adverse conditions. The system is designed to keep the rifle running smoothly, even after extended use, with fewer malfunctions than direct impingement rifles​.

However, some users have reported issues with the magazine catch system, which can occasionally cause the magazine to fall out during intense drills or operations​. This is a notable flaw, but for civilian or controlled-use environments, it is less critical. The bolt catch spring has also been cited as an area that could use redesigning for better long-term reliability.

Pros:

• Gas piston system enhances long-term reliability
• Minimal fouling, making it easier to maintain
• Performs well in various environmental conditions

Cons:

• Occasional magazine catch issues
• Bolt catch spring could be more reliable

Customization and Ergonomics

The modularity of the ACR is one of its standout features, allowing for quick changes to the rifle’s barrel, stock, and even caliber without the need for special tools. This makes the ACR a highly versatile platform that can be adapted for different missions. The rifle features ambidextrous controls, including a non-reciprocating charging handle, making it user-friendly for both left- and right-handed shooters.

The folding, collapsible stock and multiple Picatinny rails make it easy to attach accessories like optics, lights, and foregrips, enhancing its tactical capability. The ACR also includes an adjustable gas block, which is useful for tuning the rifle for suppressed or unsuppressed use.

Customization Options:

• Multiple caliber choices with quick-change barrel system
• Ambidextrous controls for better usability
• Picatinny rails for tactical accessories

Conclusion

The Bushmaster ACR offers a well-rounded package for shooters looking for modularity, performance, and reliability. Its quick-change barrel system and ambidextrous controls provide a high degree of customization, making it adaptable for various scenarios. While the rifle’s heavier weight and occasional reliability issues with the magazine catch and bolt spring may be concerns for some, it remains an excellent choice for users seeking versatility in their rifle platform​.
