It took me about 14 months but I ordered right at the beginning of the gun fiasco. I ordered a Beowulf Upper and that was completed about 3 months before the Grendel Upper and Receiver. I did the shillen barrel on the Grendel and used the Mag Pul PRS stock along with the AA trigger. No complaints. Get a recoil reducer, I ordered mine with the tank break and I still hate to shoot more than 20 rounds at a time. Kicks pretty nicely. Reloading is pretty easy but be careful AA recently changed the max charge the recommend. Quality rifle, nice service, awesome concept!
