Few guys local wanted to build these so I asked Dave Manson to make me the reamer... (BEAUTIFUL WORKMANSHIP!!!)

Long story short... we are going to make a dozen or so barrels... Remington 700 (.223 boltface) and AR-15.

This is a pre-sale if you want a barrel (i.e. I am having my Smith make barrels this month and if you want one we will add you to the list).

Cost $250 shipped for R-700 and $270 shipped for an AR-15 barrel ($20 Del-Ton barrel extension).

Now what the heck is a .357AR?

It uses this brass... https://www.starlinebrass.com/brass-cases/223-Basic/

and .357 or .358 pills...

This is .357 MAX (rimmed) data... same as .357AR.

ALWAYS START LOW AND WORK UP!!!

FYI, I bought the reamer with .357 and .358 live pilots, so your choice.

Blanks will be Green Mountain (SS or CH)... 27" and 28" lengths.

More reading here... this guy has built a few and hunts with them... he seems like he is very smart.

If you are not actively engaging EVERY enemy you encounter... you are allowing another to fight for you... and that is cowardice... plain and simple.
