I installed this Lower Parts Kit on a CMMG Mk4 stripped lower, but it will work on any Mil-Spec AR15 lower offered by other companies. The convenience aspect of it is more to do with it having an Ambi-Safety Selector, Ambi-Mag Release, and stylish trigger guard included, and just put the deluxe goodies on once and be done. The feel of the trigger is very good for a common parts trigger. I have used CMMG common parts triggers in other lowers, and have been please with them (in a non competitive role). The Ambi Safety can be installed as a std. 90, or 60 degree throw. < Use some Loctite 222 on those little screws> The Zeroed pistol grip looks like a 15 degree angle style, which I like, however it wont replace the love I have for Magpul K2 grips. The grip has storage capability, but its not water proof (if that matters) and is fastened by a 5/32 Allen Filister head bolt. (I hope you have a T-Handle 5/32 Allen wrench on your bench) If one were to buy the (complete)Zeroed Ambi Safety [$45],Zeroed Ambi Mag Release system [$52], and the Zeroed Bolt Catch kit [$23],, separately,, $120 for the three items mentioned.

Good competitive price, but top o the line parts. Comes upgraded safety selector, upgrade mag release, and upgraded bolt catch. Really great parts individually bagged componets makes for an easy install. Really like the grip, good texture, its all for a pistol lenght and i had a sba3 for it already, but stock looks good and functions well. 1st time getting a cmmg lower parts kit and I'm glad i did get it. Very pleased
