Nothing special, was trying for a real grey man type pack. I usually just use the Patagonia pack. It unzips quickly and putting the rifle back in is easy. I glued foam on the whole bottom length and the bottom of bag. Sometimes I sit on the padded part when shooting in a awkward spot. I carry some vortex binoculars a sig rangefinder,pellets, extra mags, camo face mask, black sharpie, paper for target practice, a small monopod that rarely gets used, water pouch. It used to house a ataman M2r ultra with donnyfl, but now usually the leyla 2.0 sits in the pack. I’ve been using it for quite a while. Go hiking, if I find a suitable squirrel, I drop pack and take shot. I walk and stalk, so it works well. The other pack is a Eberlestock. I really like the company, but this s20 pack is large. Like break down your ar and pack the kitchen sink in. It fits the leyla and ataman and would probably swallow up another small piece like a hw44. The cherry bomb eberlestock is really good, but a smidge to small.
