Thinking the MK18 by geissele. Gonna be a range toy mainly. Arca rail built in is OK.
What are my other options?
15" minimum, little to no flex is ideal. Will be shot off bipod 90% of the time.
Thanks again for the insight and help. Especially @TheOE800 I really appreciate it. Grabbing the lower from an ffl this week and get that put together.
