What a build.
It started out I was going to build a 6.5G for my fiance as a surprise. Turns out she hates the look of an AR and wants nothing to do with one. Crud, I have a 5.56 and a 7.62x39... so I guess I will build something of a target rifle for myself, stuck with the 6.5G.
I had a Anderson upper and lower set before it came out she didn't want one, still a pretty blank slate. Picked up OD charging handle and buffer tube kit, DD grip and stock, NiB WMD BCG minus bolt, WMD gas tube, 6.5G Forum group buy Lehigh bolt assembly. Anderson UPK, 3# curved Velocity trigger, CMMG builder LPK since I have had good luck with them and a Seekin's adjustable gas block so I could get it dialed in just right. Finished off with a 13" (IIRC) M-Lok Matrix handguard and a 18" fluted BCA barrel from Classic Firearms.
OD Buffer tube and charging handle don't match in incondecent light, buffer tube is almost gold. Natural or flourecent light they match... whatever.
Ordered an A2 flash hider for 5/8" threads. Got an A1 flash hider with 5/8" threads... whatever.
Go to assemble the lower. FCG goes in fine, safety selector fits funky. Drags on the ledge under the stop on the receiver and is binding on the trigger so there is a big "hump" in it as you engage the safety. Tear down my 5.56 and put the Velocity and 6.5 SS in it, same hump but no drag. Reassemble in 6.5G and it is the same, no drag but big hump in swing. I have an email into Velocity on that today, haven't heard anything back yet.
Lap the upper receiver (pretty cool) Bed the barrel extension with locktite and torque the barrel.
Install the gas block. Go to install the gas tube, rollpin will not even start to its hole. Note the rollpin that came with the tube is swelled on both ends, go to hardware store and get another pin, install it.
Slide BCG in and it sticks. Get it back out with a struggle. Try to tweak the gas tube and nothing makes any difference. Pop the Anderson BCG out of my 5.56 rifle and try it... fits perfect. Put the 6.5G BCG in 5.56 and it fits perfect... whatever. Not sure what to do about that. I kinda like my 5.56 being mostly Anderson and kind of wanted my Grendel to have the nicer stuff, not my iron sight 5.56 rifle.
Kind of annoying, the first two builds kind of fell together with like Ford/Chevy quality parts. The 6.5G with like Mercury/GMC quality parts is fighting me every step of the way.
