What is a riser block and with this item, is one necessary?

A riser under the front wheel will make your workout much more comfortable, keeping the bike level. A 2x4 wood scrap works just fine, just not pretty like the store bought kind.

A riser block fits under the front tire, stabilizing the front end and making the bike sit at a more natural angle. I don't know if necessary is the correct term, but it's a good idea.

You need to make sure you order the right diameter of bar for the riser. I put these on a v star with minimal effort, just go slow and take your time. Some minor modification may need to be made, and you may need to drill a hole or 2 depending on your grips and boxes.

you're just leveling a single axle popup or light camper, right? Only one is necessary, and buy it!! It's so much easier than leveling blocks ;-)

I have not seen one. The body of this is a single molded piece of plastic and is level across the top and I can't see how a riser would attach. I did a quick Google search for this model and there does not seem to be any riser attachments for this model available. Perhaps another model has one. Sorry but good luck.

No, the bigger more exspensive one works with high step risers--- this one is only designed to go up one more step high--so two risers on each side total. If you purchase this step you will want to purchase two risers(just risers) seperate.

It comes with a riser that will work just fine.....if you get a Magpul MBUS it will co-witness nicely.

Yes, it does not come with. It wouldn't hurt to get them to add more stability or to put a block or something underneath maybe?

No it does not need a riser but I do have trouble keeping it zeroed in upon rapid firing if I would have known this before hand I wouldn't have bought this product.

Comes with different risers,but be aware of the over all footprint !! Its big ! If u want it for a Laptop I recommend 3M Vertical Notebook Riser (LX550).

I have two ARs: flattop with Magpul MBUS front and rear, the other with the A2 front and MBUS rear. No riser of any kind was needed for either.

Yes, the top and bottom pieces should be attached to one another for stability. However, they will work together without the two pieces being attached. The holes between the two pieces are 3/8-inches in diameter. In my case, I bought 3/8-inch bolts and appropriate washers and locking nuts at my local hardware store and screwed the two pieces together to complete each of the risers. The risers really work beautifully and will not break like equivalent-height, plastic risers might.

Same as the other guy, I have A2 front and rear MBUS and no need for any riser. Perfect as is.

Does anyone know if I need a 1" or a 1/2" riser to use this on a A2 AR-15 front sight? Thanks

It's actually set up to use the existing seat, which you mount on top of the riser. Extra long bolts are provided for the extra height.

I believe this will fit. I used my stock riser which fits...a little slop but should be fine.

I think risers can be used although I had to take my foundation out from under my mattress when I used this frame because my mattress was too high with both. Instead, I put good quality 1/2 boards on top of this frame and laid my mattress straight on top of the boards to prevent the wires from marking my mattress.
