I will sell my beautiful baby and everything else for $2100. This is my first AR build, so it has an insane amount of sentimental value, plus I put a sh*t ton of hours finding and obtaining all the parts that I wanted. Either way, have fun trying to build one like this in this market now. I'm hearing that guns and most desirable gun parts are on back order for up to a year or longer. I am in no hurry to sell this, and please don't say that it's too expensive because, as I just explained, it has sentimental value, and my sentimental value is worth $2100 to forget about.
