u/Small_Measurement_80

I recently ordered and installed the dark grey titanium 7-round magazine tube, and I’m happy with it so far. The finish is a great match for the OEM color, and it arrived in five days.

The biggest thing I wanted to check was capacity. I’ve seen posts from people saying some aftermarket tubes won’t actually fit seven rounds, but this one fits all seven for me. Didn’t have to screw with the spring, or follower, just made sure the snap ring was flush with the very top.

As the title says, I had been having issues with my handguard for a while. It didn’t affect how the gun functioned, but it was annoying because the handguard was slightly loose and could be moved up and down.

I eventually discovered that my gun was missing a small part—the tension washer, specifically part #18. Click on photo to fully see the numbers.

If your handguard feels loose like mine did, it might be worth checking to make sure the tension washer is installed. P.S this is a common issue that QA doesn’t find in the factory sometimes.

Is the bottom of the stock supposed to look crooked like this?

Just got it brand new, costed a pretty penny but damn is it a nice gun. What are some recommendations for a brand new M4? Such as how to break it in, and must have modifications and attachments.
