no complaints about this dd upper. runs reliably and the fit and finish is nice. my only gripe is that the barrel is a little gassy. nothing terrible but noticeable. not sure if its an issue with the gas block or what. maybe i just need to tinker with it more
Just put this dd handguard on my rifle and it makes a huge difference. super solid and lightweight. the mlok slots are nice and the finish is top notch. took a bit of work to install but worth it for the improved ergonomics
well the trigger on this dd lower is alright i guess. better than mil-spec but not amazing. the takeup is a little long and the reset is a bit mushy. might look into upgrading it at some point. overall the build quality is good though
got this bcg for my dd upper and it runs like a dream. havent had a single issue in over 500 rounds. much better than the crap mil-spec bcg i was using before. very happy with the quality
the dd barrel is decent but i was expecting a bit more accuracy. its an improvement over my old wilson combat but not amazing. maybe i just need to try some different ammo. still happy with the overall build quality though
