Easy on and off. Gives you the perfect check weld.

Owner was very easy to get a long with and help me get him the dimensions he needed to make what I needed

Sir Hammy is a gentleman and manufacturers each unit with the care of any craftsman. Fit and finish is fantastic. Placing your firearm upon this magnificent stand elevates it to a status befitting it's exquisite nature.

Fits the 2k11 very well.

Product is as described, excellent design, definitely recommended.

This company was great to deal with. Extremely fast communication and reasonable shipping charges. I ordered a baffle alignment tool for my CGS Nautilus and this thing was solid! Very well made. I will be buying some of his magnetic magazine holder soon.

I was honestly a little worried that these wouldn't work for UMP 9 magazines as well but I took a chance since both the UMP 9 and UMP 45 magazine base plates look identical. When I got the mount, my UMP 9 magazine slotted it perfectly, no issues! I'm very happy these worked! I'd wager that this works for UMP 40 magazines as well, but don't quote me on that.

Amazing fit and finish, tight lock up, solid as F..... ive used the sc irregular one on a 2 builds and have had the tabs break off during classes, the hammy prints is far superior and a hell of alot cheaper. This is a must if you need a solid riser at a very reasonable price point. Highly highly recommend this one.

For the price you get excellent quality and the fit is just right! Highly recommend if your looking for a CAR15 stock cheek riser! 10/10 woukd purchase again!

Shipping was as advertised, no complaints, fit and finish was good, color should look good with some wear and tear on the paint, tight grip is pretty neat. Cap fits the head super well, no wiggle and little to no light leaks in a dark room, very pleased. Will probably buy another if I get another m640. It’s been too cold for extended range trips so I haven’t gotten to test how the higher heat material will hold up so close to the can. Not a great picture but it’s what I got. Again very pleased, keep up the great work.

Shipping was as advertised no complaints. ARD fit and finish was good, a little shiny but some sand paper would fix that, I paint my stuff though. Paint adheres nicely. Snapped onto my ECOS ACOG RMR combo nice and tight no wiggle/looseness. Can’t beat the price too. I would buy again if/when I get another RMR. Not the greatest picture, but it’s all I have on my phone right now. Also I’ve had the HRF Magwell for awhile, but it’s safe to say I won’t be getting another one now that I found Hammy. Keep up the great work.

Great product and fits very securely.

Do alot of long range shooting and sun glare plays alot into missed X's, and Hammy 3Ds took care of that. My son and I recently went on a wild boar hunt where my son had to shoot uphill facing the sun to bag his boar. With the Hammy's installed, sun glare was not an issue!

This is my fourth purchase from Hammy, and once again I’m impressed. The fit on my Aero Precision M4E1 lower is tight and secure with zero wobble once installed. It locks up solid and feels purpose-built for the M4E1.

The print quality and construction are excellent—the material feels strong and durable, not flimsy or brittle. Functionally and visually, it’s a great upgrade. The design looks clean and blends well with the lower. Overall, a high-quality product I’d confidently recommend. Don’t pay 60 to 120 dollars for the other manufacture's. At this price this is a great deal.

These covers have perfect fitment for my binos with the Steele Industries sacrificial lenses. These covers do not have a pin hole which is exactly what I wanted to make sure I never accidentally leave them on and damage the tubes during daylight storage. The tabs make getting them off very quickly. Only negative is that I did not see the color options available on when I bought them. I would have loved a green set because looking good is half of the battle.
