When you get ready to work on that .308 carbine build that you have been itching to start, you’re going to need some parts. The AR-10 platform has not enjoyed the same standardization as its AR-15 offshoot and the M5 is no exception. You can’t just slap in any old AR-10 buffer tube kit and expect that rifle to run right. When it comes to cycling the action properly, you need to get your hands on an Aero .308 carbine buffer kit and get ready to build it right.
The Aero Precision M5 .308 carbine requires a different cycle length for its bolt carrier group in order for it to properly function. This is where the Aero .308 carbine buffer kit comes into action. If you happen to grab a rifle length AR-10 buffer, then get ready for some feeding issues. A .308 carbine uses a shorter buffer and spring to accommodate the different cycle length of the action. When you install the right .308 carbine buffer tube kit it alleviates this problem.
Keep It Simple, Keep It All the Same
If you happen to be a professional armorer then you can probably take a pile of parts and build a reliable weapon. However, it’s usually the safest choice for us mere mortals to keep it simple. If you get your .308 carbine buffer tube kit, receivers, and barrel all from the same manufacturer it’s a good bet that it will all work together. The furniture doesn’t matter as much as all of those critical, naughty bits that have to play well together. So, get quality parts, pay attention, and have fun building.
