Going from standard tube to extended tube on M4...

[h.bowman]

This seems like a total noob question, but I want to ask before I go and do what I've been told I can do.

When you remove the cap at the end of the tube on the standard tube, there is a plug that the spring backs up to. How do you remove that plug?

I've been told that you can simply get a screwdriver and pop it out. Well, it is in there pretty good. I don't want to just get a screwdriver and pop it out, having only been told that by one person.

What is the best way to remove that plug?

Are you talking about the black spring stop? If yes then I would use a set of snap ring pilers and remove it that way then remove the spring and install new extension,spring and then spring stop.

Cool. Thanks for the advice. I thought there was a tool that would let that out, but I didn't want to take my gun to Lowe's and show them what I'm talking about...

No just a simple snap ring pilers works great no sense in freaking out the people at Lowes with a big GUN.

I just use a small stick or plastic pen and slowly work it out. I am very anal and with a screwdriver, may slip and scratch something. Also make sure, just before the cap comes out, cup your hand over it, because the spring comes out pretty quick.

I used a pair of small needle nose pliers. The tips fit in the holes just like snap ring pliers would.

The bolt handle also works. The triangular receses that lock it in the bolt also fit the in the releifs in the spring retenion ring.

+1 on the snap ring pliers. They make changing the position of the front sling loop a breeze too, so I'd say it is well worth the $20 it takes to buy a good pair.

I bought a pair of these today at an auto parts store. This damn ring won't budge!

hmmm.... It is possible that Benelli has started fixing the plug, not likely however. Try removing the tube with the plug, spring and follower inside. Should not hurt anything, just be carefull. -d
