I am wanting to buy a Colt 14.5 M4 barrel and Phantom FH to put on my LE6920. Since I still learning about AR's I want to make sure I get the right Colt barrel. Does my LE6920 rifle have pre machined ramps? Thanks for any help, my corworkers say it does. The ad below is for the one I am concerned about fitting my rifle

This new Colt M4 barrel came from the factory with standard feed ramps and no "F" marked FSB. What that means is it will work with everybodies A3 carry handle without a taller front sight and without the improved feed ramps it will work with any reciever with no pre machined ramps. The barrel date stamp is 7/03, has the sling swivel riveted on the FSB amd the markings on the barrel are the normal " C MP 5.56 NATO 1/7". This pre ban/ no ban barrel is 14.5" long so all NFA rules apply. Have pics if needed. Still has the card board tube in the barrel. Paypal or MO. $265 shipped. I can permenantly attach a Phantom or Vortex for an additional $35.

look at where the bullet feeds into the barrel.  the  Actually you can search the topic and find tons of info on the subject.

BTW  unless your existing barrel is fucked up, the cash you are spending on this could be spent on far better things than shortening the effective part of your 16"

You'd probably save a few $$ by sending the upper to ADCO and have them cut and rethread barrel for Phantom.
