Got the part and Jeff was very helpful when package was not delivered on the day post office said. Received a couple days later.

I haven't abused the rail yet but it dropped right in on my ATI. Not sure about the issues some other had. I would definitely reccomend for the price. I don't understand how they can manufacture it for that cheap. Seems like a quality peice so far.

Quality made product!!! Exactly as it was described.......very happy with how it looks on my rifle!

I have an S&W MP AR 15, this items fit perfectly.

Fits great I need another one

This aim sports drop in quad rail is well worth the price. It is a high-quality product and will look great on your AR-15. I received it quickly and was extremely pleased with my purchase. You can't bet this item for the price.

Couldn't be happier with this m4 drop in quad rail. Great drop-in replacement for stock handguards! It took maybe 5 minutes to install(without the proper tool). Would recommend for anyone looking to upgrade rails and not wanting to pay for a free float system.

I bought this carbine drop-in quad rail for my Anderson AM-15. It was really easy to install. I watched the youtube video from the manufacturer and had it installed in under two mins. I had read a couple of reviews on this item, stating that the screws were too short. However, I didn't notice a problem with them. They tightened up fine. I have yet to take my rifle to the range to see how it stands up to heat, so far so good.

If you struggle with removing the Delta Ring, this is the AR-15 handguard upgrade for you. Installation is easy and smooth. A little blue lock tight on the screws, and all should be well. The rails align with the upper receiver. The numbering starts at the front and increases to the rear, very functional. This M4 quad rail holds tight, stable, and survives the torque from a grip pod on the bottom, IR laser, and sling ring mounted on the left side rail.

The drop in quad rail fitment was great. It is level with the flat-top of my Bushmaster, but it is rotated just a hair, probably because the gas tube is of a hair at the back. For now, I got it closer by cheating the clamping screws a little tighter to one side. I'll vice it up and check/fix that later. It does come with the pads for unused rails. I had a plastic/composite one before. This one is a lot more solid. All my sites, bi-pods, foregrips, and adapters have fit it just fine. Like it!

Shocked on quality. This forearm for the price is unbelievable. Easy install, light weight, and well built.
