I took the bolt out of the carrier and lube it up and using just it and the "go" gauge it locked up fine but with some elbow grease. I'm thinking it's as alot of people have stated it's just a tight fit and needs broken in..

I used a "go" gauge to test and it was with the bolt complete. I'll take the extractor off and oil it up as after reading more post on here i'm thinking that could be some of the problem. I think i'll scrub everything good and then "dip" the bolt in some synthetic oil i have and try the "go" gauge again......thanks again for all the suggestions and help..

Put the firing pin back in and borrowed a head space gauge and as i see it, the bolt is about a 1/4" shy of locking up completely. If i take the gauge out the bolt slips right in......never have had this happen on a build before.,....

I to have the Matrix set up of the upper and lower i bought of GB. I also ordered the 18" barrel that AIM surplus had on sale and purchased a dpms compatible bolt to go with the barrel. Putting the lower together wasn't a big problem until i ran into the same problem everyone has of the spring being to short for the rear take down pin. The problem i've ran into is after tightening the barrel on and checking the head spacing with a round (i removed the firing pin first) the bolt will not close completely. Barrel is flush on the inside and the round seats good but the bolt will not close all the way in the receiver. Any ideas what i might be missing as i think my brain has shut off for the moment and gone blank......thanks in advance.

Got my wrench friday and it fits like a glove.......thanks again Toolndie7!!!!!!!
