[M1014 recoil tube removal]

Dave -

Glad to help. You do not need to remove the sights. You will want to remove the trigger pack, bolt carrier and disassemble the existing receiver extension by removing the snap ring from the end, and unscrewing the plug. Careful of the spring tension inside there. I put a punch thru one of the drain holes to retain the spring. Once apart you can dump the plunger out. For a solvent, spraying it out with break cleaner would be fine. You’ll likely see smoke, but I’ve never had flames from whatever lubricant the factory uses. Keep your flame on the jam nut and the neutered receiver extension.
 

Be careful where you clamp the receiver in the vice. You don’t want the jaws on top of the trigger pack takedown pin. I mostly clamp below the rear sight and flip the receiver upside down when needed. The jaws can chew up the takedown pin if the receiver is pivoting on it. Be sure to use some kind of padding between the receiver and the jaws to prevent marring. 
 

I think I have to do two of these later tonight after work!

 

Just a quick shout out, the two that SD is working on is for me! I think it goes without saying that the M4 world is better for having SD in it. Thanks man!

[GG&G Tactical Bolt Release Question]

This happened to me as well, though it got so bad that the spring was completely deformed. A buddy gunsmith of mine theorized that the spring that came with the GG&G bolt was a different tension then the factory spring and that's what led to the spring coming undone. We put the stock spring in and I've had zero issues since.

[Dropping weight on the M4]

Hi Folks,

 

I've fallen into the rabbit hole of modifying my newly acquired M4 and I'm wondering besides the titanium magazine tube and dropping the iron sights, what other option are there for reducing weight? 

 

Thanks!
