It's got a tactical rail about the higher receiver and an adjustable stock. The DEF10 has an individual phase cause and comes along with 1 twenty-round Magpul PMAG. It's an MSRP of $999 as well as includes ArmaLite’s limited life span warranty.You bought it right. It is a screw-on choke tube. It's no less than similar to the Lyman/Cutts choke tub
