I talked to a guy @ coleman tyler who sttd these are thicker than the vltor mur and he has actually seen one after a round exploded in the upper...he sttd it was still in specs and had only minor nicks ....
sun devil makes lowers for POF but without the mark up...
I purchased the upper for 139.00 and the lower for 139.00 since they were being shipped 2 different places I got dinged 2 x for shipping at 6.85 usps priority....
now...
the build changed to a billet upper and lower.... that price couldnt be beat....
oh...these are the new generation lowers with the checkering
I am pleased with the 138.95 price tag on the "flat side" a3 upper....
I am hearing nothing but good things about them although there are those out there that argure the 7075 forging is superior to billet, it goes in one ear and out the other...
I took this upper to the gun shop today and it fit tight on every lower they brought out...stag/noveske/cmmg etc and it was significanlty beefier than even the vltor mur....
for 138.00
I dont think I will ever buy a standard mil-spec receiver after having this one....
oh and the coating is even better.... its sateen like teflon but confirmed its just a better than mil-spec anodizing....
I just purchased them last week so I assume the batch is new... colemantyler makes runs to the SD shop there since they are not far from each other...
My upper has no engravings or markings and it has no fwd assist or deflector....
He told me that if there is any issue with fit.... use the adjustment screw in the lower.... he said they should fit tight to most rcvrs and if not that is what it is there for....
He said there is no use for antiwalk pins or an accuwedge becuase of the tightening screw available....
he also said that they do some special anodizing to get the uppers to come out with a "satin" look....
oh.... I love the checkering on the front of the mag well....
ONCE THE UPPER HALF IS ASSEMBLED I WILL POST PICTURES
