Hi Jase, i just took my biscuit off today and put on my trapdoor mac 4 rest, went to the range to shoot and wow what a difference, in about 15 minutes i was shooting 2 and 3 inch groups at 35 yards, the rest was really easy to set up and it dropped every time, i dont like the dropaways with cords or springs thats why i got the trap door and i'am glad i did, if you get one i hope you have the same luck as i did.
