Hi, I have the Briley mag tube extension with the +1 extension and their spring. I was just wondering how long should the spring be? I was running it at their stock length, which seems to be ok so far, but have seen some people trim it down.

ah ok thats good to hear. I think I've had it for half a year and only shot about 20 rounds out of it.

How often do you do a tear down to clean and lubricate the M4?

quick question, once you twist the extension off, does the spring come out or is there a c clip in place?

https://www.briley.com/p-63665-benelli-m4-one-shot-extension.aspx this is the only part at the end that twists.

I just realized I don't need to remove the spring and c-clip just to take out the upper barrel to clean right? Just need to remove the end cap, but the spring won't pop out.

Hi everyone, I had upgraded my benelli to use the Briley magazine tube and extension as well as their spring. When my friend put it together he said the tension was really high, I was wondering what is the best and safest method for removing the spring for maintenance? Thanks,

I circled the parts in red, just wondering what it’s Called and where to get them. Thanks

Got it I have an idea. Is the button easy to remove from the stock?

The one from cal guns look nice, but I don't think he's making them anymore.

Any instructions for that route?

I like how simple this one is. https://www.youtube.com/watch?v=IT5JrkS6eBY

hmmm

Hi I was wondering if there was a kit or a diy on how to pin the m4 c-stock? I got one coming and I live in California so that’s why I need to pin it some how.

You have the a zooms?
