Great to know. My M4 (11715 LE) is due in this Friday.
I ordered the same choke based on a lot of searching and calls but that Carlson number is for the C with no teeth, so it’s not the same in the picture. That’s the 85006. https://www.midwayusa.com/product/1005265674?pid=378169&utm_medium=email&utm_source=service&utm_campaign=shipping-confirmation&utm_content=product-shipped-today-product-description-link
Carlson told me the 84030 is the best for recoil. Ordered this after I ordered the Carlson 85006 IC based on my first call to them. We’ll see what works best. New to the M4.
Hoping to put rifled slugs, 00 Buck, Target loads through it with one choke.
