The New and Improved Pro Quad Rail Lightweight, Rigid, and Easier to Install The quad rail is still the gold standard of secure accessory mounting, but they’re in desperate need of a reboot. That’s what we offer with the AT3 Pro Quad Rail. It uses the same simple installation as our SPEAR M-LOK handguard, has plenty of lightening for maximum comfort, and it works with Mil-spec uppers, as well as our Billet Upper to match the sleek contours. The Pro Series Rail comes in 7, 9, 12.5, and 15 inch lengths, making it ideal for upgrading existing guns or starting fresh with specialized AR15 builds. If you’re planning a build without a Front Sight Base, make sure you pick up a Low Profile Gas Block with the handguard. Simple Installation: Installs easily, just like our SPEAR M-LOK rail you’ll only need a few simple tools to get the rail installed. Click here to view our instructions. Perfect for assembling a new build or upgrading an existing rifle its compatible with most mil-spec upper receivers on the market Once you’ve got it installed, you’ll have plenty of room for any Picatinny rail accessories like lights, foregrips, lasers, or bipods Seriously, its easy.

The anti-rotation tabs are a definite plus. 15 inch rail. That is very sturdy material is quality. No worry about stripping screws. the finish is quite good and for the price these can’t be beat. All tools included to install even barrel nut wrench.

I got this rail for a pistol build for my wife and I love it. Fit and finish are nice and the price point isn't crazy. This rail has a nice snug fit on the barrel nut, the included tool was a nice touch especially for those with limited gunsmithing tools.all the machining is on point as well, no issues with any accessories attaching or becoming loose. All and all this is a great handguard at a good price.

I am normally a M-Lok fan boy, but wanted to build something a little different. In walks this stout beauty, making me forget my M-Lok allegiance. She is ticking off all the boxes, feels like I am dreaming. Once installed I realize I am not dreaming. Anti rotation tabs checkQD attachment points on all 4 corners checkWeight saving cut outs down the pic rails checkWeight saving cut outs at 1, 4, 7 and 10 checkCuts make gas block adjustment easy checkRigid checkStraight checkMade in the U of effing S A double checkOnce I start meaningfully handling her I realize I either have to glove up or add pic rail cover/ladders. She has some bite, she is a quad rail after all. Still seggsy as heck and look forward to some new calluses.
