Great barrel - Apex Tactical Specialties Grade Threaded Semi Drop-In S&W M&P Barrel

I got this product to replace my factory barrel and it works great and Easy to install. I used it on my m&p9l C.O.R.E Pro series along with Apex extractor, trigger kit. I noticed the shot groups tightened up and have had not malfunctions so far. I like having the threaded barrel for suppressor or compensator. Overall I would recommend any Apex tactical product, they are worth it.
