Question: Will it reverse sides for a left handed shooter?
Document: Fits an old Winchester M-37 16ga single shot just fine. And mounts fine on either side of the stock so lefties can use it too.The elasticity is strong enough so it grips the stock snugly and holds 16ga shells well too. How long that will last, I have no clue since I just received it today. So far though, I think it deserves 5 stars, even for left handed use.
Love it. Wish it had slots on both sides but I bought this one and I enjoy it. Looks cool and works well. It does slide a bit when used extensively but hey it's a good product
this shell holder has a nice snug fit for 12 ga shells. is not loose or poor fitting at all on my remington 870 tactical. i felt the plastic side saddle would break and shatter if dropped plus its very bulky. this is a simple no b.s. design.
Works well on a new Remington 870 Express. Installation is easy, drop it over the barrel, run it down to the stock and pull it in place. Holds 5 12 gauge shells snugly in place.
Very pleased with the quality of this product and it should last me a long time. In my opinion, it is worth the price I paid.
This shell holder fits well and is made of good quality materials. My 20 gauge shells fit very snug. I would buy more if needed.
This shell holder appears to be stitched well and fits the butt stock perfectly. I would recommend this product as a good buy.
This one works. It is a quality made piece. I would buy it again. The shells stay nice and tight but can still be pulled out for quick reloading.
This item when onto my shotgun stock with a little bit of work but stays nicely in place. Holds the shells. It does what it is suppose to do.
This is exactly what I wanted. Had to remove the recoil pad to make installing it easier. Found that going back and forth...pulling it over the top then the bottom of the stocked worked best. Now if fits tighter than OJ's glove. Looks great, made well and no problems with shooting.
Answer: yes
