12.5” for general purpose, agree. A part i disagree is when you said you were gonna use a 13.9” to “reach out a little farther”, my brother in Christ just use a 16”. Better fps. Run a stock, no pin and weld. If you really want to pin and weld, go with the 14.5”. Better fps, same pin and weld.
@@Mtn_Marty your feelings on the 13.9” don’t outweigh the facts that a 14.5” or 16” is better. Clint Smith would say pick one or the other, stop dicking around in the middle. Your chest rig is also ass. hOw BoUt ThAt?
I like your paint job very nice. Tactical Hive Guy's "Coch" did a barrel length velocity test , it's amazing how 1" can increase the terminal velocity too fragmentation . As a GPR you have to include out to 300 in that figure, too get that you'll have to start with 3000 fps min. base line. I don't know what length under 16" can do that, maybe a 13.7 or 14.5 can, I don't know. I do know that from 10.5" to 12.5" doesn't have terminal velocity at that distance, that's not too say they can't reach ,but not with terminal velocity, so they aren't considered GPR's . All of the shorter rifles were developed for CQC or CQB in Afghanistan for closer range (in building's, huts etc.) work, for that they are perfect out to 100yrds . That's why the 300 blk-out was developed as a quieter more leathle round under 100 . It's not relying on fragmentation, the 7.62 with less velocity creates a bigger permanent wound cavitation = BIG HOLE ! So the 300blk made all the MK-18 (10.5") MK-111(11.5") types less desirable, because the 300 very short suppressed is so much quieter for CQB. Also remember fragmentation has two purpose's more damage and less over penetration, you need 2600 fps min. to frag, which gets you back to the 16" barrel for 3050 +/- velocity with M193 55gr. That's why they switched to M855 62gr.more effective out to 300yrds.with SBR's . Just say'n, I like that paint job 👍 😎 THANK YOU for sharing.
I love my 13.7 pin and weld. Compact enough for inside work and more than viable for longer than cqb ranges. Put together a 13.5 AR10 just for giggles also and can't wait for the snow to clear to see if I can make it do 500yds.
Aero has an awesome sale going right now. If you buy any upper you get a free BCG and charging handle with free shipping. I picked up a 13.9 for $492 shipped
16 inch is imo the perfect barrel for a general purpose rifle build. I’ve seen videos of marines clearing buildings with a 20 inch A2 with that long ass fixed stock no problem. A 16 inch barrel and an adjustable stock will give you alot less length to maneuver in CQB situations. And the 16 inch will also give you the length and velocity to hit targets 500 yards out no problem. So with the 16 inch barrel you can do pretty much everything fairly easily but at the end of the day it comes down to training. Give a newbie a 12.5 barrel CQB build and have someone who’s been training a-lot with a 20 inch A2 clone and then dude with the A2 will crush the newbie with a 12.5 because he put the time in to train.
Currently don't have 12.5 but I really want one. I agree a 12.5 is a great choice for a general purpose rifle. There is a study out there with sensors per every inch of barrel and it showed some solid data. Velocity readings from 12.5-14.5 were pretty much the same and only really increased when nearing 16". Oh and 10.3 makes little sense when you see that you get a massive FPS jump by just adding a single inch and again even more so when adding another inch (12.5). Funny enough I own a 10.5 gun. My other favorite option is actually a 16" barrel. yeah it's getting a little longer but it's still able to do CQB relatively well and has a very good velocity increase and with modern day propellant mixtures is around 150 fps off a 20" barrel in many 55grain loadings.
nice vid and sweet set up! personally have a 16 incher cause i cant be bothered to go through nfa shenanigans and i like my stocks. also epic bunny spotting at 11:49
Hope you escape in time. Looks like things are getting rough in that state. Pretty sure there's an 'underground railroad' near wine country, should you need it...
Nice build. Personally I like the BA 13.9 Hansen barrels with a P&W muzzle device (they come with a pinned gas block and on sale are really inexpensive). Still pretty short but great velocity and a very soft shooting barrel that makes accurate follow-up shots a breeze.
@@Mtn_Marty Hope he's trained to operate a slide and charging handle in SPITE of having no opposable thumbs. Mine is... Had to use extra treats in the training process, but it worked
I have a few Criterion Core barrels I will say you will not regret it. Great shooting barrels I do have their 12.5” and 13.9” and they both get sub moa with 77 gr IMI Razor core
@@Mtn_Marty if you want a bomb proof set up look into Ripcord Inds. Gas Hole gas block. They can be a PIA to install but well worth what you get….. Super Tight but you will get no gas leakage past gas block and if you use locktite or Rocksett to your screws it will not ever move
08:25 hand on that muzzle brings out my Marine Corps weapons instructor vibe filling my lungs to capacity ready to pounce on a recruit for violating two of the rules of weapons handling... 😂As YTer and 2A personality you gotta remember to stay solid on these things. Thanks for the vid.
hi i was recommended this video to me by youtube your narration is pretty cool, i watched your video from beginning to end. my GPR is super chunky (almost 10.5lbs loaded with all attachments) so now I'm looking for diet accessories for it. 16" barrel with LPVO and light. i really don't fancy having a 5.56mm carbine heavier than grampaw's M1 Garand. also some kind of jackrabbit or another one of god's creatures was hanging around at 10:55 lol
So @arisakadefense lights are lightweight. What kind of lpvo are you running? Maybe sell it and scoop up a lighter one like the new 1x8 from @primaryarms. It’s compact and light.
I have the 12.5 pinned. Lighter bullets for higher velocity work well. Feel I am wasting powder on heavy 308 bullets. Found 125 grain work well. I got the heavy cmmg barrel for tree stand hunting. But gonna go out coyote hunting some time with it. I may go sbr or suppressor with it. It's loud a.f. now.
I run a 16 inch gun. That way no worries about rule changes that aren't legal anyway. LOL It's a mid length gas BA 4150 V that is cold hammer forged and coated. I run a decent coated BCG, and trying to get an A5 buffer system on the way for an upgrade. Oh, my upper, lower, and 15 inch handguard are all Cerecoated in FDE, for cool points. I run an FDE ROMEO 5 XDR red dot, and a matching Juliet 4 magnifier. Both are at 1.63 mount. Oh, and MBUS of course. My sling is an FDE Vickers, by Blue Force Gear, and is attached by QD. Simple I guess. It all works well, and never hiccups. It has eaten anything I feed it, but I settled for ONLY using PMC X-TAC M193. I have kept it simple, and mid-grade. LOL
@@Mtn_Marty Thanks. I looked at yours for a bit to see if I could get any ideas for my next build. I have everyone of the small parts. I do mean everything. I just ordered an Aero M4E1 assembled upper receiver, and looking to get an empty matching lower, both in FDE. Then use my spare barrel and bolt carrier group. LOL I liked the info you gave us. Thanks again.
Good stuff, hell of a rig. I do like the route you're goin with it, I'm actually runnin a sons of liberty 13.7 pinned, runnin a dead sir sand man s, the little bit of extra barrel length makes a pretty big difference and still a very handy rifle with good ballistics and velocity.
You are going to be VERY impressed with Criterion barrels. I used one for my last build and it is the most accurate barrel out of all my rifles which include Noveske and Daniel Defense.
Great rifle set up and review. This upper was my first build and I made the right choice for my needs and wants. Could you please do a tutorial on how you painted this rifle? I’ve wanted to paint mine but I haven’t found one that I like until I saw this video.
Subbed off of this video-- very cool set up on that GP rifle. I'm still building mine, slowly... I *would* also be interested in a 'battle belt' video, since yours looks pretty cool, and I've started thinking about building one has well. I'm not trying to build it on the cheap, however, anything that's 'not too expensive' is always appreciated
Myself, I wouldn't put an LVPO on a GP rifle. I'd put a red dot and a 3 x magnifier on it. Now, on a Recce style rifle, definitely an LVPO with a piggy back or 45* red dot for up close and personal.
I actually stated that exact caveat in the video. A GP should be set up to cover most of your assumed mission set. Because there’s so much wide open space where I’m at I like some magnification. However I also have a rifle set up with a 3x mag. But honestly, great point man.
@@ronin2167 all good my man. Like I said it’s a valid point. Just got to set things up for you. So many people get wrapped up in what the latest influencer does when in fact they should look around their AO and make informed decisions for their kit.
It’s one of their kit bags. The larger one. I threw a hook and loop 3 mag insert into the back and have a kettle bungee wrapped around the back to keep the zippers together.
Sure thing! Copy and paste these links and it will get you completely set up. I do get a small kick back from these and that helps me continue the channel. 12.5" Aero Upper - alnk.to/b7vmEGA , Lower - alnk.to/4My5lkS , Lower Parts kit - alnk.to/aLFQH5j , Trigger - alnk.to/b7vmENM , Scope - alnk.to/7X1J08K
@@cottojn you could however my understanding is that 7.62x39 gets super slow in barrels under 16” but I’m no AK expert. If you really want smacking power with a short barrel get a 300 black out upper.
Hi Jose, I have experience with AKs in 7.62 and with shorter barrels. A couple of points. First, loss of bullet velocity due to barrel shortening is less with a 30cal bore than a 5.56 because of the additional volume. Expect 123grain steel ammo to still get over 2000 fps out of a 10.5” barrel. Second, loss of velocity isn’t the same problem with 7.62x39 that it is with 5.56. The latter relies on its speed to create fragmentation and wound channels. The former relies on being a big piece of metal. The previously mentioned 123grain bullet is over twice the mass of 55grain M193 5.56. Third, the primary advantage of 300blk over 7.62 in my opinion is plentiful subsonics. Subsonic 7.62 exists but is temperamental and it can be difficult to get reliable function since the AK platform is harder to tune. 300blk also offers a common manual of arms to 5.56 ARs, which is a big deal. Having said that, there is no reason to not have a 10.5 or similarly short AK pattern gun that shoots 7.62. They are fun, easy to handle, relatively inexpensive, and effective. I have used a 10.5 shooting hollow point 7.62 to humanely drop large hogs. I have yet to have to track one down after impact. I hope this helps.
Tons of post online about Aero bolts breaking prematurely. Id go with BCM bolt, but the Aero upper itself is pretty good. Though imo Aero doesnt hold a candle to DD, BCM, FN, Colt, or LMT. If i were to only have 1, it would certainly NOT be Aero.
Well, we are at about 7k rounds on this setup with literally no problems ever. I've never heard of Aero bolts breaking any sooner than other brands but the internet is a large place filled with experts...who knows! Probably a good idea to have extra BCGs on hand regardless of the brand of rifle you are running. Also, were you aware that almost ALL brands use tool craft BCGs and just rebrand them?
