So i am debating buying this
Barrel for my Colt 6940.
I really like the shorter barrel and i have always hated the standard front sight on the 6940's. i know the A2 front sight is probably considered a downgrade but i really like the way they look.
The problem is i fairly new to the AR world. i have had this gun for about 5 months now. i know a lot about AR's but i have never worked on them, just basic maintenance and cleaning.
What all do i need besides the barrel? CMMG offers a number of add ons:
Delta Ring assembly ($11.50) i dont think i need this because i have a free float assembly, but would like to know if im wrong...
Front sight Gas block 2 options: .750 marked ban compliant front sight base CBP (+$45.00) or Micro Gas block (+$60), i really want the A2 style front sight so i should go with the first one right?
Sling Loop and Rivet (+$2.50) what is this and do i need it??
Gas Tube and Roll Pin (+$12.50) do i need this?
Bolt Carrier Group: Bolt head spaced to barrel (+59.00), Bolt head spaced to barrel semi auto (+159.00), Bolt head spaced to barrel full auto (+159).... i dont think i need any of these but please tell me if im wrong
Also, how are these barrels? i know Colt barrels are solid so im not sure if its even worth the change. i think CMMG is a respectable brand but they are clearly behind colt IMO. do you guys think it is worth the upgrade?
And last question, Do you think this barrel will fit my current Hand guard? if it doesnt im definitely not going to buy it... i emailed CMMG but havent heard back form them.
Thanks for the help in advance!
Also this is my first post here, i have been lurking for a long time and finally decided to make an account.
Here is a pic of my current build:
