First AR Pistol Build-Thoughts?

[CCC23]

My first AR build was completed a few weeks back and I though I'd share the end result...
My 10 year son did most of the work under my supervision of course. He watched U-tube, then gather parts, rewind, watch again and start working. It was a proud moment when he looked at me and said " Dad, I hate detents!" We must have launched that thing all over....lol. Special thanks to Nate getting us started with the stripped lower and flip ups!

Spikes lower / Spikes upper / Spikes lower build kit
7.5 Barrel w/ KAK Can
Slim Keymod w/Ergo Grip Angeled Foregrip and covers
PWS Buffer tube kit
YHM Iron flip-ups
Trijicon Reflex

Looks like a nice flamethrower, and a great time spent with your son. Can't wait to do that one day with my kids.
I would eventually get a cowitness mount for the RMR if I were you guys.
Have fun with it. Those little things are a blast.

Thanks, Co-witness mount is on the way. I was on the fence weather to leave the RMR lower since the flip ups align just above. After shooting it I agree with you, co witness is the way to go.

Nice package. If you don't mind, what was cost less optic? Once you build one its like potato chips...........

Right at $1000. I found I could have built a complete PSA pistol for right around 550-600. I figured for 100-150 more I could go all Spikes. Nothing against PSA at all but felt Spikes had more brand equity.

Moved to the AR section. Please be sure to post in the appropriate place.

That's an excellent build. As far as my thoughts, I too have a kak type can on the end of a 11.5 pistol build although it's a 300blkout. It makes it really kick so its hard to maintain a good check hold with rapid shooting. I ended up with a muzzle brake after the second range trip.

What brand and how long(9"?) is the slim keymod. Looking for similar look on build I'm planning.

I have an 8.5" Bison 6.8 and wished I had built it w a 10.5" barrel, my use is hunting though and now it shoots pretty flat 40-100yds. For a blaster I guess it is not as important. I put a scope on mine and may return to a red dot or holographic, the scope makes it too heavy and iron sights with my eyes is a no go. Then again I don't need it and may sell too as I have 2 16" rifles that I use most of the time, it is the bottom one in my Signature.

If you plan to use it as a "pistol" ..... with a SB-15 or other,the gun is gonna be super short anyway. As to not loose tons of velocity I would stick with a bbl of 10.5 - 12.5 inches. I have one with a 10.5" and it still makes for a super short and fairly light package.

BUT ...... I suppose that if you plan to shoot the shorter distances and you pick the right load,the shorter bbls will be adaquate. --- SAWMAN

7in slim keymod w/ 7.5 barrel. The KAK adds close to 1.5-2 inches to over all length. I just picked up a 10.5 upper in 300 for reaching out a bit longer. 50-75yrds would be as far as I'd shoot.
