View Full Version : Question on Barrel Diameter
Just out of curiosity, what is the purpose for the smaller diameter section on the AR's barrel an inch or two in front of the front site?
This is where the attachment clamp of the M203 grenade launcher (http://fr.academic.ru/pictures/frwiki/77/M4-M203.jpg) is located.

Well, I figured there was a legit reason for it. Thanks for the info! Don't really need a grenade launcher, as this is the HD gun, and I am in a very small home. But, if I win the lottery and get a huge house, will look into it.
Thanks!

Fred, that was the best response I have seen in 2 years---good question---no stupid questions; someday someone will ask it anyway---your answer was response to Quib was perfect! Seriously, love it and nothing wrong with it.
Thanks for the info!
Thanks!
No problem, that's what it's all about. Helping each other out regardless of the question. [:)]
