Thanks, I just found your channel. I kind of settled on H2 for all my ARs.
3 lengths of buffer tube. Strike industries makes a smaller tube an buffer to be used with or without their pdw stabilizer
So much easily digestible information in this video. Thank you!
I have a Spike’s T2 buffer in my 11.5 Spike’s Tactical. With a JP Enterprises tuned and polished spring. It shoots like a dream, without the annoying twang that my old DPMS had.
Best video I've seen yet on this. I'm dealing with 2 builds from scratch.
1. 16" 5.56 / .223 that feeds and extracts but no LRBHO ( I do need to try a different mag, only had 1 at the range during cherry pop time )
2. 10.5" 5.56 / .223 that fails to feed and sometimes extracts ( potential gas block issues – unconfirmed)
I am relatively new to all this. Please keep making the highly informative videos. Stay Rad. Stay safe!
I have the JP Enterprise buffer system I love it!
I’m digging that upper and rail. How it cuts into receiver and no fa.
I am curious, does it matter if a carbine buffer weights move on the inside of the buffer? because I have a 5.8oz with solid none movable weight inside the buffer, and I switched it with my standard carbine buffer,on my 16" 5.56 AR, but instead of it helping. it made my ejection go from the basic 3 o'clock pos. It jumped to around 2 o'clock being way over gassed, and still had no problems with ejection. Shouldn't that much weight have stopped my system from ejecting at all
I wish there was a chart with calibers, barrel and gas lengths, and buffer weights breakdown. Old school text book style. Just finishing a .458 socom build and finding an accurate weight setup that isnt just "start with this and adjust from there" is kinda lame. There has to be some sorta math based/measured number system to selecting buffer setups. Unless I just havent found it.
Miss you Randy on BRS! Their videos feel stale now.
A good combo for carbine 308 with 20 inch barrel?
Awesome video
Running a VLTOR A5 with a Sprinco "green" spring on a BCM 18'' rifle length gas upper. Super flat shooter with minimal felt recoil.
Great break-down. I just wish a video like this with a break-down & recommendations for buffer assembly setup for running different uppersin a variety of calibers would pop up, smack me, & yell watch me, ya idjyit.
You missed the 3rd A5 system that goes between carbine and rifle buffer systems.
I run a VLTOR A5 buffer system combined with a Geissele Super 42 rifle spring, great for the money and haven't seen a better setup yet
Geissele Super 42 spring and proprietary H2 buffer makes my 16" mid-length rifle shoot like a dream. Very light recoil, cycles perfectly, and definitely no spring twang. I also purchased a spare tungsten weight in case I needed it, but it turns out it's perfect as it is. I mentioned proprietary buffer as the spring won't slip over the shoulder on a standard buffer due to it's decreased inside diameter. Since the spring is built to last, it should be the last spring/buffer set I'll ever need to purchase.
If I have a PSA 8.5 inch AR pistol, what pistol buffer tube are my best option to give it reliability?
Randy saying corals instead of corals made me smile….. and miss him even more
A5 H2, rifle length mil-spec recoil spring, mil-spec diameter A5 length tube. There are 3 types of buffers.
Is weird to see you talking about AR 15 instead of reef tanks but lucky for me I enjoy both, 👍👍
You forgot VLTOR , intermediate😂
Just to confuse people a little bit more.
