Excellent product, lightweight yet sturdy. Love the echo feature, it is a lot of fun!

Great gun and fun to shoot but I had to purchase a few of the correct magazines for it because the one that came with it was the wrong one looks like original 300 black out Magazine was swapped out for some cheap magazine I contacted Gun prime spoke with manager at customer service and told me to contact fostech instead of just mailing me out the correct magazine he also said he would make a phone call and try and correct the situation and would get back to me but still no phone call also missing some important instruction manuals were missing that suppose to come in the box which were very important on how to field strip the gun and to correctly put back together because it does have a binary trigger and needs to be put together a certain way with out damaging the rifle a week later still waiting on Manager from gun prime to get back to me regarding sending me the correct 300 black out Magazine after spending 1820 for rifle it should of came with correct magazine other than that everything else was good fast ship was delivered no issues it’s one of my favorite rifles
