It’s nothing special and installation sucks - Stern Defense SD MOD4 M-Lok Handguards

I ordered this because I needed an 8” handguard and they’re hard to find, this was the cheapest I could get and optics planet got it to me quick. My first impression was that the barrel nut was aluminum (which I’m not a fan of in rifle caliber) and there was no barrel wrench included for the very unique barrel nut. No barrel wrench and it’s definitely not standard meant that I had to use a pipe wrench which made it difficult to get the torque specs right. Additionally the stupid barrel nut has notches for your gas tube which means it must be timed WHICH I EFFING HATE! I had to use the included shims which I also hate but one shim wasn’t enough and two shims were too much so I had to play with the shims and probably ended up over torquing it in the end. The design of the nut just seems so dumb and over complicated to me. The handguard itself is alright, not a slim handguard and not overly lightweight, it’s usable and seems rugged enough not to bend or break. The anti-rotation tabs are nicely designed and will work with any upper receiver unlike some other brands. My only other complaint is that the handguard is has a bigger diameter than the upper, making a ridge between the two. This is the first time I’ve seen this. So in the end, it works but not my favorite. I’d say it’s ok for pistol caliber carbines and 22’s but it’s a PITA for anything that needs a gas tube.
