StrangerDanger Posted May 6, 2013 Share Posted May 6, 2013 I recently received a top rail from Freedom Fighter Tactical to install on a friends M4. Since I had my carriercomp top rail removed for my coating process, I figured I'd take some decent pictures and compare the two side by side. Generally, the carriercomp top rail has been the 'go to' rail for anyone serious about mounting an optic to their M4. I noticed that Freedom Fighter Tactical had released an offering that looked quite similar to the carriercomp rail. At various times, the carriercomp rail has been extremely difficult to get -- so an alternative is welcome. While the Freedom Fighter Tactical rail costs a little more than the carriercomp rail, it also includes a set of washers and fasteners. The Freedom Fighter Tactical rail is also available for purchase at pretty much any given time with minimal wait periods. The rails themselves are nearly identical. The only differences I noted was that the carriercomp had a more aggressive dehorning process performed. This means there are fewer sharp edges present. The carriercomp unit also has T markings present. The finish on the aluminum is different. On the carriercomp, the finish is shinier than the Freedom Fighter Tactical model. The Freedom Fighter Tactical model has more of a flat subdued finish. Installation of these rails is pretty straight forward with the proper tools. Procuring a proper flat head screw driver for the fasteners is probably the biggest challenge. The bit you want is a Magnabit 240-6. They fit perfectly. You'll also want to use a torque wrench. Torque the fasteners in an alternate pattern like if you were torquing the lug nuts on a car. Eventually snug them all to 16 - 18 inch pounds. Locktite is recommended for the fasteners. I would take an additional step and coat the fasteners and receiver threads with Locktite Primer. 243 Locktite is recommended for two dissimilar materials. You can make due with 241 blue locktite though. Allow the fasteners to dry for at least 24 hours before shooting the weapon. Bottom line is, you can't go wrong purchasing either one. 1 Quote Link to comment Share on other sites More sharing options...
