BOTW: Kevin's AR9 Build

by Tom R

The 23rd Installment of Build of the Week was contributed by Kevin. I really like the look of that hand guard. If you all can’t tell by now, I really set this series up to get good ideas for the stuff I want to do. Pete finally convinced me to em-brace PCC builds and this is a nice clean one. It does need a can. And the backdrop needs a nice marinara sauce… How does it shoot, Kevin?

We are doing installments 23 and 24 back to back in a shorter time window as we have a huge surprise coming up for SHOT. Voting for Set 6 will be on the 9th… Stay tuned and definitely cast your votes.

Keep the submissions coming in! We are publishing them in the order in which they were received (with the exception of a single person submitting back to back–those will get spread out).

Greetings TFB Team!

This is a 4.5” AR9 build I completed in January of 2018. The parts include:

MAS Defense side charging upper and barrel, KAK 9mm flash can and a Troy 7” Alpha rail with squid grips, along with Troy Battle sights (HK style front) and a JP 9mm BCG (v2).

The lower is a 9mm Quarter Circle 10 (Colt Pattern), with a Rock River Arms lower parts kit, KNS pins, Radian Talon ambi selector, Magpul K grip and JP Silent Captured buffer in a Maxim Defense adjustable pistol brace.

Thank you!

    The entire concept of PCC's tickles me. Everyone who thinks a 9mm small carbine build as being new, never lived or trained through the 80-90's. During the 80-90's the vaunted MP5 was the gun of choice if your department could afford them. They were also the most copied. They were the supposed "killing machine" and even the fiction novels followed suit. Now we're almost 40 years down the road with numerous cartridge improvements, and today people gasp at the possibility of using a PCC as a primary defense weapon. The prevailing logic behind this being that a 5.56mm or .300 ACC carbine are better in all ways so why even considder a PCC?

    As someone who trained with and was assigned a MP5 during this time frame all I'll add is that PCC's, especially if shooting USPSA events, are a giant load of.. fun!!! Everything important/vital with a PCC we can't possibly know from photographs. The best we can do is guess. I'd rather have a really ugly and rusty well tuned PCC, than a new & shiny yet to be tuned PCC. And there really is a lot of knowledge/skill/techniques/equipment choices that goes into a well tuned PCC. Check out the USPSA build foruns to see what I mean. But when well tuned they are a load of fun like you wouldn't believe.

    THIS build certainly looks the part. Kudo's to the builders sense of taste. I'm not fond of any "brace" that has velco or material prone to catching on the shooters word fabrics. I'm also not fond of anti-walk pins.. they're not necessary if the piece is well built and most people use them for looks. The hand guard has a large outer diameter. One of mine has a 5.5 inch barrel with a 16" aluminum shroud and a thin foam protector around the shroud making it a very easy PCC to drive. Finally, PCC's really benefit from a RDS.. This build promises a lot of fun.

    Tom,

    Exactly what KNS pin kit did you use please?

    What a cool build, I hope to emulate it.

    Thanks,

    Mark
