Another outstanding product and service from One Hundred Concepts
I love these caps and how well they work and look! Buying was simple and the process was quick both times. One of my scopes wasn't listed so I contacted Briana with my scope measurements and she helped me find the right caps. I'll be ordering more soon for my new HK MR 762 A4 and new Vortex Razor. These are good looking, tough and long lasting in their simplicity. Thanks, James
The Holosun 507 ARD is too easy to knock off (it is on a TA02) but a cable tie secured it. Also the grid could be deeper (and/or a short awning on top front) for more signature reduction. ACOG ARD is good.
Love these and they work great. Very nice. Would recommend
Excellent product, shipped quickly and arrived in perfect condition. Very happy with the purchase. Highly recommended!
Work as intended
I haven’t had the chance to test it in real-world conditions yet, but I have no doubt about its high effectiveness. Furthermore, the HexCap Kill Flash/A-R is a very well finished product that perfectly fits the EOTech EXPS3-4 HWS Red Dot Sight. Hundred Kudos to One Hundred Concepts for this brilliant device! Best regards, Laurent from France.
The fit and finish is always top tier. Simple and effective. No rifle is complete without some one hundred concepts gear.
I bought some cheap ones off Amazon a while back. Learned the hard way that regular plastic makes a lot of noise when they clang against metal or other hard surfaces. These are quiet.
Fits like a glove. Perfect sizes.
The kill flash (ARD) fit well and look like it should have come from EOTECH this way. I like the protection it adds to the lens. Bought two, one for each Eotech.
Love the feel the ergonomics are awesome
Love the product, the only issue I had was the front scope cap didn’t fit snug, I had to put black tape around the scope to get it from falling off. Some instructions on how to put it together would have been nice as well.
Good product
Solid. Is my edc tq. Might get more for my kit.
Nice to have didn’t need it!
It’s a great product doesn’t fit legacy turbo heads for my M900 surefire but it’ll fit my scout!
Top notch product.
I’ve been trying to get these for probably 2 years and they seemed to constantly be out of stock. Stumbled onto your site one night and everything was is stock, so I finally got protection for my scopes.
Good to go
Good stuff.
I don’t get why charge extra but cool
Didn’t use it, if I needed to it would’ve been nice to have!
Was looking for a pistol grips that would suit me better than any other brand. The closest one I could find was a B5 systems pistol grips amd that still made my wrist and hand feel weird. As soon. As I found the video on YouTube and noticed they had a left handed version l, and not universal, I ordered it. As soon as I installed it onto my ar, i knew I had found the right grip for me. It fits comfortably in my hand and places my wrist in a comfortable position to not have to feel like im gripping my fist tightly just to keep it in my hand. I highly recommend this product for anyone who is looking for the perfect pistol grips for shooting.
Stop sending be review requests! Fuck this company
The grip is great 👍 helps with one handed manipulation and shooting of my AR I am going to buy more
excellent
Bought a "Kill Flash" for a Vortex Venom and two sets of scope caps for two Vortex Crossfire 3x9 for rimfires. All work flawlessly. I am done with using anything else. Thanks for a great product.
Easy to order Easier to use.
Perfect solution for my kit. Thanks! Can wait to get my hexcap!
