First off, I am thrilled that I found this forum. I just bought my M4 a few days ago and am waiting for it to get to my FFL, and have been combing this forum for information and has helped tremendously.
However, I keep reading about the Different Magazine extensions that some of the guys on here provide to M4 owners and I unfortunately know absolutely nothing about them.
Can someone explain fundamentally how they are different from the stock Magazine? Obviously they have more room, but do they extend the overall length of the weapon? As in, do they go past the end of the Barrel? I know its a dumb question, but I am clueless on this one. I only ask because I see various tube sizes (+2 extender, 5, 7, even 10.) I personally would like to get the largest magazine available and legal in CA that is within reason without f'ing up the integrity of the weapon system and only plan on doing this once.
This is the only upgrade I plan on doing besides the enlarged Bolt Release, and possibly a Red Dot sight after I become proficient with the Irons and truly learn the weapon. Any advice on the difficulty of the Bolt Release swap is also appreciated. I am a former Infantry Marine, but am certainly no Gun Smith or Armorer, I Just like to shoot thanks Gents.
