Question: Dumb question but cant hurt to ask .... will 20mm attachments fit on this rail? i like the compact pistol lasers that ive found, will they fit??
Document: Have no problems with this item. It has held snug, with no sliding, or losing grip. Only issue Ive ran into is the length is a bit long for a short flat top, so the iron sights will either get in the way, or you will have to remove it, which I wouldn't recommend. However if you want to run with zero iron sights, this will fit perfectly.
The rail fits like it should no slop, no excess movement just plug and play. Also a good price for neck comfort.
I like the product, it is heavy, simple to install, has lots of extra rail space to put up to 6 devices on it at once. I am not sure what would happen if it hits the ground or a hard surface, meaning it may break or may not.
This anodized aluminum rail fits perfectly and aligns straight. It is 5 3/4 long, 2 inches wide, and 1 inch high. The length could be cut 1 inch shorter from each end for a length of 3 3/4 inches. Top quality and machined for all picatinny attachments. My only complaint is it weighs 8 ounces.
I did a lot of research on-line for a riser or rings which would compliment the iron sights of my CX4 Storm and allow a magnifying scope to clear the sights. This item fit the bill of being 1" high and allowed me to still use the iron sights. I also felt that it would provide a more stable base than high rings and it had side rails for other accessories. The side rail sits above but very close to the cocking handle which could be a handicap in rapid deployment situations.
Easy to install. Good fit. Nice and tight. Gives me the height I need. Without this rail to increase the height of my scope or red dot mounts, I can't correctly use hearing protector muffs. With low sights, the AR 'stock' pushes the right ear muff up and negates it's protection.I was able to mount (using an off-set light mount) a light on the left side, with it's rear cap off/button 2&#34; forward of the bolt release.
This is put together well and made from high quality aluminum. It's easy to install and does it's job. What more can you ask for? Admitedly, I didn't install this as a scope mount though. I put it on the bottom forend rail for my AK. I needed a bit of height so that my my UTG angled fore grip would clear the ATI stock. See pictures. I had another one of these a few years ago on a flat top AR as a Riser though and it was great.
I needed a riser for my rifle and i figured if it has to be a riser it might as well include some picatinnys for attachments and this one has three of them. Well worth the money.
If you need to put weight some place, this is the way to do it. This thing is definately heavy. This is a very solid mount, well made, excellent fit.
hello i bought this riser for my project salvo paintball gun and it works great it just adds more waight than you think its solid all steal construction and will not fall off ive had it on my gun for 7 months and not even a wiggle all in all its a good riser for the price
