Comes with different handguard, but it still works well - Alexander Arms AR15 Standard Rifle Upper

Decided to buy from the brand who developed the cartridge instead of a cheaper alternative like radical or BCA. I was a little disappointed that it came with a different handguard than in the picture, but the upper functions very well. When installing the upper on a lower I had to tap in the rear take down pin because it was very tight. Some people say this is a con, but I think it’s a pro because it makes the gun more accurate and feeds more reliably. This will probably vary based on what lower you have. I recommend using an H3 buffer.
