ordered a red 18 x 20 mm cf tube to re do my mess , i took the droop moderator off and have a ugly end of the barrel with no cf shroud , about 7 inches , thought about removing it and redoing it with a full ln. new cf tube but got to thinking , maybe a go over the one that is allready on the barrel . so i ordered a 20 inch red n black cf tube to slide over , am going to have to remove a part where the bottle is , but i think it will look good , any way any one that has done something like this as for what type of glue or resin would like to hear about it , will help me for my installation , its going to happen! im tired at looking at the ole ugly mess , but it is quiet now with the new huggett , very quiet ! and ugly !
