Let’s Talk About Griffin Armament Griffin Maritime Receiver Extension
The Griffin Armament Griffin Maritime Receiver Extension isn’t just another buffer tube; it’s a thoughtfully designed component aimed at enhancing reliability in adverse conditions. Griffin Armament has built a reputation for quality, and this receiver extension promises to uphold that standard. With its innovative port design and robust construction, it caught my eye as a potential upgrade for my go-to AR-15 build.
My quest for a more reliable AR-15 led me to this product. I’ve experienced malfunctions in the past due to water and debris entering the buffer tube. I was looking for a solution to mitigate those issues.
Unboxing the Griffin Armament Griffin Maritime Receiver Extension, I immediately noted the clean machining and smooth, hardcoat anodized finish. The 7075-T6 aluminum felt substantial and reassuring in my hand, a far cry from some of the flimsier tubes I’ve encountered. The weight felt appropriate, not too light as to feel cheap, nor too heavy to unbalance the rifle.
I considered a standard mil-spec tube from Brownells and a similar offering from BCM before settling on the Griffin Armament Griffin Maritime Receiver Extension. Ultimately, the maritime ports and the use of 7075-T6 aluminum, promising superior strength, swayed my decision. The price point was also a factor; it was a worthwhile upgrade without breaking the bank.
My first impression was one of cautious optimism. The design seemed intelligent, and the construction appeared top-notch. I was eager to see how it performed in real-world conditions.
Real-World Testing: Putting Griffin Armament Griffin Maritime Receiver Extension to the Test
First Use Experience
My first test was at an outdoor range in less-than-ideal conditions: a drizzly, somewhat muddy day. I wanted to simulate the kind of environment where moisture could become an issue. I put about 300 rounds through my AR-15, deliberately getting it a little dirty and wet.
The rifle cycled smoothly, and I didn’t experience any of the sluggishness or failures to extract that I’ve seen with standard buffer tubes when moisture is present. The Griffin Armament Griffin Maritime Receiver Extension’s ports seemed to be doing their job, allowing water and debris to escape. I didn’t need any time to get used to it; installation was straightforward, and the rifle handled as expected.
One small surprise was how easily the tube wiped clean after the range session. The hardcoat anodized finish seemed to resist mud and grime effectively.
Extended Use & Reliability
After several months of regular use, including a few dusty range trips and a hunting excursion in wet weather, the Griffin Armament Griffin Maritime Receiver Extension continues to perform flawlessly. I’ve put well over 1000 rounds through the rifle since installing it. There are no visible signs of wear and tear.
The finish is still in excellent condition. It’s as easy to clean as any other AR-15 component. Compared to my previous experience with a standard 6061 receiver extension, this one inspires much more confidence. I’m no longer worried about a little rain or dust causing malfunctions.

The use of 7075-T6 aluminum is significant. It offers approximately twice the strength of the more commonly used 6061-T6 aluminum. The ports are also critical, as they prevent pressure buildup and potential malfunctions in adverse conditions.

I have not experienced any failures related to the buffer tube since installing it. It inspires confidence that the rifle will function even when exposed to the elements.
The tube’s primary strength lies in its reliability. Its only weakness is that it may be slightly heavier than some ultra-lightweight alternatives, but the added durability is worth it. It has definitely exceeded my expectations.
