I thought I would see how others have blinged out the 2k. I currently have the double charging handle, buffer tube cover, Folding rear sight, and was looking for a good hand-stop when I came across this lil fella on Amazon. It’s cheap enough that if it breaks I’m not upset. Feyachi PL-31 Laser Sight Compact Shockproof Red Dot Laser Sight with Picatinny Rail for Pistol Handgun Shotgun Rifle https://www.amazon.com/dp/B08KVX2VST/ref=cm_sw_r_cp_api_glc_fabc_VVe2Fb7H9Y2WK?_encoding=UTF8&psc=1
By mounting it to the bottom rail it acts as a hand stop and the on off buttons are on the sides by your hand. I’ve got it dialed in at 40 yards to where I can look down the front sight post and it is spot on with the post. It also eliminates the goofy cheek angles on the stock when wearing classes and ears at the range.
