Hell you can have.both. all you need is a barrel and a wrench. Then just decide which one you want to shoot first.

I have several shilen and i like them very much. Never had a criterion. Just ordered a barrel from NSS yesterday. Talked to him about both. He really didn't push the criterion. Could be because i always get.the shilen select match.

Also have.bartlein and kraiger. In fact i am ordering a bartlein dasher barrel from bugholes. Just called them. They haven't haven't woke up yet.
