Installing Buffer tube, Spring & Spikes Tactical ST-T2 Heavy buffer.

You need to tight the Castle nut to 40 pound

Thanks!!!

I love 5.56 ar, but if i had to upgrade caliber I'd skip 300 bo and go 308

Go with a 5.56mm barrel. Ammo is still ridiculous for 300 blackout.

I think you left out your detent pin for the rear take down pin.

clear and easy. good stuff!

556 is p shooter 300 blackout is as small a round as will go on a pistol 556 is basically a 22 with high velocity i reload my own so availibility doesnt matter to me

Thanks

nice tips & vid!!!

good video, I'm installing the same buffer, how do I get the original one out?

Thanks a bunch for sharing. Excellent tip on that rear takedown pin and spring as well as the tip on the buffer spring assembly. Now go kill some Zombies!

When I purchased my grip, I didn't even get the bolt with it. It was a pain because lower receiver kit didn't include the bolt either. Kinda sucks when companies trying to cheap out by not including necessary hardware.

Understanding that the only thing you need to do to switch between 300 blackout and 223 is to change the barrel. The 300 Black out is the same shell casing as the .223/5.56 that has been trimmed down to accommodate the larger caliber bullet. So it works with the normal .223/5.56 upper. Just change out the barrel to the larger 300 blackout barrel and load 300 blackout ammo and fire. Switch back to .223 just switch the barrel and the ammo again.

your videos are the tits! thanks!

good luck trying to find 300 black out 

I use a little dab of grease to hold my detents & springs in place while I assemble. It just kind of holds them in place & makes for smooth operation. 
I love that T2 buffer. It really makes a difference in felt recoil. 

I just got the 1.1 space gray no washer either man..

Excellent video – installing same items – didnt even have to replay…perfect length and explanation – flawless install on my end – so Thank You for your time and effort !!

Did you stake the castle nut or use thread locker?

cool think i can do that

awesome video, thanks 

NICE JOB…HOW DO YOU LIKE THE SPIKES BUFFER?

i'm currently debating the same exact thing for my mega arms lower… decisions, decisions.  i already have a regular AR, i sort of want this one to be different.

Then I wouldn't use it. Always smart to follow the directions.

My Miad states in the instructions to "not" use the star washer.

nice….

lol

You tell me I don't know much and then you say I'm building an AK-15? I don't know what that is either. I have an AK-47. Yes I'm still learning with the AR-15 but when I'm done I'll know more about it and how it works than most people that just go out and buy one. What I do with it is none of your concern. I have no intentions of going out and killing people. If that interest you then I'm sure just a plain stock AK-15 will work for ya.
