Atf 4999 issue has kak type notches - Strike Industries AR-15 Pistol Buffer Tube Kit

I am attempting to comply with the ATF 4999 and get the least amount of points to ensure my AR pistol remains in compliance. I purchased this after watching the YouTube video indicating and showing it only had drainage holes and no notches. Unfortunately this is an AR-type Pistol Buffer Tube with Adjustment Notches (KAK-type) giving me 1 point on section 3 of the ATF 4999. On the positive side this now places my a PSA 10.5" CARBINE-LENGTH 5.56 NATO 1/7 PHOSPHATE 12" M-LOK SLANT MOE PISTOL KIT at exactly 26 inches. I ordered the Phase 5 Weapon Systems Inc SB Tactical Pistol Brace Upgrade Straps to make this a “Fin-type” brace NOT lacking an arm strap ensuring I don’t get an extra 2 points. My backup sights give me 1 point and I can use a red dot without a magnifier because if I add the magnifier it will now place me at 4 points because the Presence of Reflex Sight with FTS Magnifier w/ Limited Eye-Relief is worth 2 points. These kak type notches are really an issue for those trying to keep points to a minimum.
