It's not a big deal Ron, I was ordering some other stuff from Midway and saw the DPMS spring was in stock so I added it to the order. I've been taking my time on this build so I wasn't in any rush. Heck, the trigger group in it right now is the Mech Armor one from my LR308. Besides, all this extraneous schit I get and change out down the road goes into the bag with Josh's Matrix set. Let him deal with it! Bwaahahaha!!!
