Tactical Extended Long Rail Cantilever Mount 0.5" Riser with 25 Slots BM2505EX

Awesome and exactly what I needed on my m-4 ebr

I had to locate my prism scope all the way to the front because of the short eye relief. That was sorta ok but I had to bury my face in the receiver to get my eyes close enough I had my stock adjusted all the way forward too. This piece allowed me to adjust my stock further back without losing any eye relief. I t was almost already zeroed in after installing it. The end is a little warped but I'm sure it could be straightened but it works well just the way it is.

Well made, sturdy with quality fit & finish.

I used this rail extension to mount an extended-eye-relief scout scope (a Burris 200261 Ballistic Plex 2-7x32mm) to my single-shot rifle.The good:- This rail extends the length of your Picatinny rail forward by 14 slots (almost 6"), which is enough to mount a forward-mounted "Scout Scope" on your rifle, turning any rifle into a Scout Rifle!- At only four ounces, it's very light weight, which is also good for making a scout rifle.- This rail is much cheaper than hiring a gunsmith to install a custom scout-mount on the barrel of your rifle. Besides, not all rifle barrels are suitable for mounting a rail, due to their thinness or taper.- Fits any rifle with a Picatinny rail on top (and should fit weaver-style rails as well, but I haven't tried that).- Right now, Lion is about the only manufacturer that makes rail extensions long enough for a scout scope.The not-so-good:I subtracted one star because in making the product lightweight (4 oz), Lion seems to have sacrificed some sturdiness. The front of the rail can be flexed by hand. This is probably not a concern for short to mid-range shooting using non-Magnum calibers, which is typically what forward "scout scopes" are used for. However, if you're planning to put this on a sniper rifle, or do long-distance hunting using Magnum calibers, I suspect it may be less accurate than a sturdier mount.However, the only competing products I know of that were sturdier are either too short, or were discontinued, including the discontinued "Yankee Hill Machine Half Inch Rail Riser 11.25 Inches Long YHM-9590" (which another review mentioned) and the discontinued "Weaver Tactical AR-15 Picatinny Rail QD #99659" (which I also own, but my Weaver-brand rail wasn't long enough to mount a forward scout scope, which is why I bought this Lion scope extension).

The rail itself is great the screws however not so much the Allen wrench that was sent did not quite fit like it was a standard when it needed to be a metric or vice versa I contacted the seller and to their credit they sent me a new set of screws very quickly however to get them tight like I wanted I used a dremal to cut a slot for a flat head screwdriver I then worked fantastic. However in only felt comfortable doing that after I had an extra set.

Wound up working great adding extra length to the top rail of a Ruger SFAR with an M-LOK forearm. Can add iron sights, reflex sight, and have enough room for detachable scopes and a drop mount torch.

I bought this as I needed a longer picatiny rail to mount my Holosun red dot and separate 3X magnifier only to find the rail is slightly thicker than the mounting base of the Holosun sights. I tried with a similar Romeo and Juliet setup and same thing. It is not made to spec. It did accept a ATN rattler as it has a more forgiving mounting base (allows for wider aperture of mounting plate) but can see it being a problem for mounting systems true to regular specification and sizes.

I was looking to put iron sights on my ruger charger so I wanted a longer rail that could do so, and still mount my dot sight, worked perfect, long enough so the sights had good radius and still plenty of room for the dot sight, good for the money, good for the show, good to get ready, and good to shoot some moe ammo,
