Sears will take $50 and you’ll never worry about this again. If you’re planning on installing one of these, get yourself a set of crowfoot wrenches that fit your torque wrench. lbs., the wrench twists into an ugly paperweight. I know this because at anything over 40 ft. One hilarious outcome of this was that I found out that SI’s included barrel nut wrench is precisely calibrated to 40 ft. The SI system works, and I’ve got not doubts that it is solid, but you should be prepared to set aside a few hours to do this job right. The best one I’ve used so far is Noveske’s NSR, though it is a bit heart wrenching to wail on your upper with a torque wrench until everything fits properly.

This is not isolated to just Strike’s handguard, and I’ve had this problem with every free floated Key-Mod system out there. That process means torquing the barrel nut, removing the upper from your vice, sliding the handguard in place, checking the timing, removing the handguard, placing it back in the vice, unscrewing the barrel nut, adding an included shim, torquing the barrel nut, and you see where this is going right? It is a painstaking process, and one that rarely goes right the first time. The reality deviates from the book every so slightly as you need to time the barrel nut just so.

Once you have a bare upper, do as the book says, use a bit of moly grease, spin the new barrel nut on, torque it down using the included wrench, and install the handguard. Installation is about as snappy as any other FF handguard out there. I like options and the Mega Fins certainly delivers. That’s a whole lot of rail estate, and does give you the option to run things like lights in a more ergonomically sensible place. The last thing I noticed before I mounted the Mega Fins to my Palmetto State built upper/lower was that the Mega Fins is an octagonal shaped handguard which allows for a Picatinny top and seven (!!!) sides for mounting Key-Mod attachments. That said, they provide a nice texture for bare handed manipulation. And while I flunked out of engineering before ever taking heat transfer classes, I have ripped apart a pretty decent amount of computers filled with heatsinks, and I’m pretty certain that for these fins to have an effect on the barrel, they’d need to actually touch the barrel. In my testing, I ran some pretty quick strings of fire, and I didn’t feel that it cooled my barrel any faster than any other free floated Key-Mod handguard.
SI says this helps aid in heat dissipation from the barrel, a notion I’m not really qualified to argue with using any hard data. The second thing I noticed was the “fin” texturing that covers every surface of the aptly named Mega Fins handguard. Long story short, this thing is pretty dang light, but seems very sturdy. My scale showed it a tenth of an oz heavier, but that’s close enough for me, and not something I’d ever dock a company points on in a review. Strike Industries shows 9.20 oz on their website so I give them props for including their barrel nut in the overall weight, as more dishonest manufacturers might neglect that. My fairly reliable food scale registered it at 7.25 oz by itself, and 9.30 oz with the barrel nut. įresh out of the box, the Mega Fins rail immediately impressed me with how lightweight it was. I got the opportunity to try it out, and I’m mostly a fan. Strike Industries has a Key-Mod handguard that features a cut out for an A2 sight that claims to be lightweight, durable, and endlessly modular thanks to Key-Mod as part of their Mega Fins line of handguards. As a guy with small hands, I can certainly appreciate the slimmer profile provided by not having Picatinny rail sprouting from every surface, and I generally enjoy a lighter gun whenever possible. I’ve had the pleasure to try out a few, and over the last few months I’ve started to form an opinion of them as a whole.
Direct mountable to both M-Lok and Keymod.Free floated Key-Mod handguards seem to be all the rage. The innovation in this grip will keep you happily stabilized throughout your shooting experience. At the rear of the grip, the curve can be used as a hand stop. Using these grips, shooters can apply different techniques to adapt to various scenarios: At the front, a ridged face allows a shooter to brace the rifle without worrying about the grip moving around. The LINK-CFG is constructed of 6061T6 aluminum- making it ultra-durable for continued use. The Strike Industries LINK-CFG (Curved Fore Grip) design was derived from our Cobra Tactical Fore Grip and features SI’s (patent pending) LINK system which is mountable to both M-Lok and Keymod rails.
