You could probably be the Where's Waldo world champion... Sometimes is hard to find a damned AI handstop, a bolt seems almost impossible.
And yes I just wanted to use the Waldo comment...
You have a complete bolt, you trump me. I have a bolt body and head.
As to why, simple. My 300wm 2.0 becomes a .338 lapua with a bolt and barrel swap. But I still have to pull my firing pin and safety off swap as well.
What caliber is that, 308? Looks short from the pic
