Works as i hoped it would - Pro Mag AR-15/M4 Polymer Quad Rail Carbine Handguard PM242

I was desirous of a carbine-length quadrail for my new Del-Ton AR-15, but wanted something lighter than aluminum, plus something that was easier on the hands. I found both with the Pro Mag Polymer Handguard PM242. It's considerably lighter than traditional aluminum versions, and is less abrasive. My attachments fit securely and accurately on the Picatinny rails, too. No buyer's remorse with this product.
