    Micro ARP Build

    Posted by Paul Kuehn on March 5, 2024

    This was one of the parts I needed to complete a micro ARP chambered in 5.56 with a 4.75” barrel, 5.5” M-Lok handguard and fluted flash can. KAK has some great products and fantastic customer service too.

    Loud as hell.

    This is a good little barrel. It sounds like a large caliber gun going off when you fire it.. It works great with the micro gas tube.Both are a little over priced for what you get. But they work.

    This is my 3rd 4.75 inch barrel I have them all now. Love KAK products! Customer service is great. now for the barrel I haven't finished my build yet but I have 4.75 in .300 BO and boy is it fun to shoot. cycles fine no false feeds or cycling issues, so I'm sure my 556 and 762 will be the same. thanks again KAK

    The Short Boom Stick

    Posted by Sj on November 26, 2020

    I first ordered this thinking it would be impossible to be accurate and cycle the rounds adequately. I was shocked and amazed . It was more accurate the 7.5 in 223 Wylde stainless barrel I had . I bought it to intimidate the guys in the range and hopefully for self defense. It did both perfectly. If you want a home defense barrel that can fire 77 grain projectiles and go through walls so it goes to the intruders and not wait for intruders to come to you . This is it! Recoil is minimal. The concussion blast shakes the walls . They have increased the price of the barrels but still worth it .
