Kaleb's Review of Monstrum Side Mounted 12 Gauge Shell Holder

I ended up ordering two of these. I liked the first one so much. You don't have to drill and tap the sides of your shotgun to install. It was a simple and easy install on both of my Mossberg 500s. Really enhanced the look of both of them too and gave the capacity to hold six more shells on the gun. I haven't tried to use the picatinny rail yet for an optic, but i do plan to in the future. Overall 10/10 on this product.
Pros:
  • added 6 rounds on the gun
Cons:
  • None
Would Recommend: Yes
