This is some weapons grade stupidity here. 
Okay... so this is a two part test. If you score a 4 or higher on either step then boom you have an SBR and are a felon! You have to add up the points for each and every category that fits your weapon. eg if you have a split type stabilizer and it folds that's 3+1 = SBR. 
There is a lot here to get wrong. You think you have a 3 point brace but forget that you have a hand stop, not a vertical foregrip just a hand stop. That's 2 points plus 3 and you have an SBR. The weapon weighs more than 120 ounces - automatic SBR! Sight/Scope with Eye Relief Incompatible with one-handed fire - you guessed it SBR!
PREREQUISITES 
1. The weapon must weigh at least 64 ounces. * Weighed with the magazine. unloaded / accessories removed 
2. The weapon must have an overall length between 12 and 26 inches. * Length measured with all non-operational accessories removed 
If you meet both of these prerequisites you proceed to the SBR test Part 1.
PART 1 (Total up points and if you get 0-3 then proceed to PART 2. If you score 4 or more congrats you own an SBR!)
