Outstanding upgrade for a ruger ar 556 - Pro Mag AR-15/M4 Polymer Quad Rail Carbine Handguard PM242

I have a Ruger AR 556 and wanted a way to securely mount a vertical foregrip to it. This looked like a quality part so I decided to give it a try so I ordered it. It is PERFECT! It was a perfect fit on my Ruger AR 556 and thanks to Ruger's twist up and down delta ring it was a breeze to install with no tools. I was surprised to see that my original Ruger handguard had no heat shields inside them. They never got hot no matter how many rounds my son and I put through the gun at the range, so I always assumed there were heatshields in them. Well, there were none in the factory handguards but there are heatshields in these Pro Mag handguards so they are actually better than the factory handguards. I mounted a Magpul RVG to this Pro Mag handguard and it was a perfect, secure, solid fit. I took the rifle to the range and fired 60 rounds through the gun with the vertical grip attached and both the Pro Mag handguard and Magpul RVG remained solid and secure with no play at all. This is a quality product that looks and fits great and I was once again completely satisfied with the fast service I received from Optics Planet. I like this so much I'm ordering another for my other AR 15.
