Questions & Answers
“Product Info” clearly states that this includes the BCG and CH. “Features” state in all caps DOES NOT include BCG or CH. So which is it? Expert Answer

This does not include a BCG or a charging handle. Would have to purchase those separately.

Caught it on sale... by JMV, Verified Owner, August 10, 2023
Fantastic deal even when not on sale. Aero makes solid in spec parts that fit very well on what ever lower you're looking to use. Make sure to select the deal that includes the Charging Handle and BCG, for less than would you pay if bought by itself.
