Yes, this jig is used to finish an 80% AR-type lower receiver and includes a lot of items that normally do not come with the jig if you buy it new. Shipping is included in the above price (and it's quite heavy).
This also includes the 1/4-28tpi tap for threading pistol grip hole. Reamer is steel straight machine type whith 1" shank that has been turned to 1/2" for use in a hand-drill(normally around $30+ each). Buffer tap is Brownells brand tap ($40-$50). I've got around $300 into this jig which has only been used twice. Everything is in very good condition.
