Great item. shitty turnaround time - Kinetic Development Group Modular Receiver Extension, Compatible w/ all 7.62 & 5.56 SCAR Model

It took about 5 days for my order to get processed then another 3-4 day for delivery. I had to change my original order from getting a Sig Sauer Juliet FDE magnify scope after waiting from the beginning of April to changing my order in July. Cause I wasn’t going receive the item till mid September. Beware this store says they have things when they don’t. I checked the sig site and they don’t carry a FDE magnification scope. No one does but this company. The mrex rail will be my last purchase from this company till the can change their shipping speed and have a ready to ship stock on hand.
