Esstac 7 is great product.No need to drill shotgun's reciever.Just buy velcro at Homedepot.Stick it on reciever(clean it with alcohol).Stick ESSTAC 7 shell holder to reciever you're good to go.I shot numerous shells (mostly slugs and 00 buck) still holding super strong on reciever.I own Mossberg 590 and Benelli M4.
Fantastic! So good a made two purchases in the same week.
My latest creation is the modern stagecoach/mad max/resident evil gun. My daughter thinks it's stupid but I said what if we still had stagecoaches, this is what the shotgun guy would carry. She said, we don't have stagecoaches anymore and I will take my 1301 any day... It's a Stoeger double defender with a Holosun HS510C red dot. If you haven't used optics on a shotgun you should, it's awesome. Slug head shots and all the buck on target every time! A Streamlight TLR-2 HL provides light and laser illumination. Two Gray Man Tactical 7 round Velcro shell holders provide 14 rounds of ammo, you can slip a few more of these in your pocket for quick replenishment. A Blackhawk sling with a Michigan Industries sling adaptor holds 15 more rounds for a total of 31 rounds of on gun firepower. I am impressed with how this gun patterns and a decent trigger means decent slug shots. Yeah, it's not a realistic fighting shotgun but it's reliable, accurate and fun! It's also plain old bad ass. Nothing says git like a good old double barrel. Excuse me while I make up some dime loads.
