Decent for the price – Have only put about 100 rounds through but functioned fine. The blemishes were very minimal on the upper receiver and I liked that you can get it shipped without the muzzle device torqued down. So far, to me, the upper was definitely worth the price.
Just as described – Fast shipping and no issues with the item, couldn’t tell you what the blem even is. Very happy, will purchase from Midstate again!
300 beast – got this as a backpack 300 w/law folder and sb3 it fits in my alpha niner evade 1.5 and vertx readypack (very tight muzzle dependent)
shot it yesterday. shoots great. loud and big boom. ive never shot 308 nor a pistol/carbine length before this to compare but.. big boom
gun looks awesome and feels sturdy and well put together and doesnt have hammer marks at every roll pin point so they used someone smarter than me to build it. killer deal for the price
thanks
GREAT DEAL – The only blemish I THINK I found is the coating on the receiver is very thin and matte, but still doesn’t scratch easy. No scuffs or misfit parts fit my pistol lower PERFECT but I’m not sure if it’s mil spec or not
Waiting – I still haven’t received it
