This combined with an Anderson upper is a hard combination to beat. It is a MilSpec so expect the usual rattles and interesting noises. But that is why I got it for reliability and it will shoot any type of ammo I put in it 1200 rounds and only one FTE and no FTF's. Reliable and durable will purchase again if I build another one, Buds shipping and handling was as usual great and I highly recommend you get the insurance with all the products you buy in the firearms category.
