Well I got my barrel from Compass Lake the other day, and as I ripped open the box with as much excitment as a kid on Christmas morning I noticed that the barrel is......threaded. Not at all what I was wanting. I recall placeing an order for an 18" Douglas Stainless Steel SPR profile barrel with m4 ramps and 1:8 twist and matched bolt. I never mentioned anything about it being threaded and with this being my first build ever, I somewhat assumed that SPR implied it being unthreaded. Noob mistake, but I have learned and will move on! I take this as a sign that someone just wants me to add a suppressor to this project when the funds come back around. For the time being does anyone recommend a good muzzle break/flash hider for under $100? And also, to fix this problem in the future do I just specify unthreaded? or something about pre/post ban?
