I am about to finish assembling my first AR carbine.My set up is a used Colt M16A1 lower receiver with a Full auto feature and also a slightly used Colt M4A1 upper receiver and barrel(14.5 Inches(Nato 1/7)).Now someone is offering me a brand new Bushmaster M4 carbine also with a Full Auto feature in exchange for my Colt M16A1 lower and Colt M4a1 upper receiver and barrel set up carbine.If you were me,would you accept his offer or not?And why?
Thanks.
