UncleJon Posted September 8, 2008 Share Posted September 8, 2008 I have an M4 with a factory 14" barrel, both stocks and the extended mag tube. I'm looking for a factory 18.5 barrel so I can use the extended mag. I've had no luck tracking down one of these barrels for sale. If anyone knows where one is hiding please let me know. Thank You for any and all help! Quote Link to comment Share on other sites More sharing options...
