This bench is as solid as a concrete bench. It is sturdy enough for shooting out to 1000 yards or more. The vertical stem is made of 4" diameter, 1/4 " steel pipe which revolves around a center pipe of the same thickness. The legs are 2" square steel tubing with 1/4" sidewalls. The top inclines up and down for hill shooting by means of a turn buckle. With a good front rest or bi-pod and a good rear sandbag, just aim the table. The 3 legs have about a foot of vertical adjustment for setting up on hill sides. This bench will weigh about 90 pounds. You get detailed plans with a material cut list and actual pictures. Many purchasers of these plans build the benches on a trailer as is mine. Blue prints and package plan for this heavy duty, 360 degree portable shooting bench plans are $8.00. Plans will be emailed as a PDF file only. No hard copies through USPS. Note; As of September 2015 I am again building custom rifles. Email richardscustomrifles@gmail.com Thanks, Richard Franklin
