For ALL things ar15 far as spec, money ABSOLUTELY DOES NOT ALWAYS BUY QUALITY. Go channel School of the American rifle, armorer knows EVERYTHING

I despise those guys at the range with brakes and no suppressor. I’m reminded of Clint Smith: “muzzle brakes reduce the awesome recoil of the 5.56 cartridge” 🤣🤣🤣🤣🤣

Buy the best you can afford, *but know where to find value.* Fancy buffer tube & parts kits? Nah, fam - spend those dollars on ammo and training. Geissele trigger? Only if you've got an extra $200 to burn. Buy LaRue MBT2S or ALG/Schmidt single stage. Put those ducats toward an optic. Muzzle device? Suppressor mount for your suppressor. Otherwise keep the A2, it's actually really good at hiding flash.

Sons and bcm are both made by microbest. Sons is my go to, lifetime no questions asked warranty

Hell yes! Having built several AR platform rifles I have learned most of those lessons the hard way. When I first started and heard people talking Geissele triggers this and that I didn't buy into it, I mean a trigger is a trigger right? Then I put one in that I got on sale and holy mother of Eugene Stoner did I become a believer, I absolutely love the SSA and SSA-E triggers. My first builds were done on the cheep which in all honesty I don't really regret because it allowed me to play around and screw up and figure out what is really important. The thing I have found out the most is you have to have a clear idea about what you are trying to build and get out of the build so that you can know what you need to get the first time. Also if you can have a long time line you can find some smoking sales if you just wait around. As always great video, thank you so much for all the great content.

Love Aero's trigger guard that comes w/a screw versus a roll pin - nothing will get me saying 4 letter words more than trying to drive a trigger guard roll pin in.

Manufactures have got 4150 Nitride Barrels down so well its hard to find a bad one. Microbest Phosphate or Chrome is the way to go for a BCG. There has been some testing by the military for DLC coted bolts, and so far, its becoming pretty favorable.

I know someone who bought a aero precision lower and a bcm upper and Mated the 2 together. He also stuck a bcm spring and BCM H buffer. He also checked that his rifle's lower was Within spec after he bought it. I would argue his Rifle has the exact same if not even better reliability than a factory BCM gun.

A friend of mine just had a knights lower fail with a bolt catch/release roll pin. I nearly cried. Lol

Hey brotha, got an update on the Ruger Readydot non-powered red dot. Actually works very well in conjunction w suppressor height sights. Lines up perfectly w those. So, if no ambient light, you've the night sights for sighting. Would I replace my other Trijicon or Holosun red dots - no. If I was on a budget and needed a sub $100 dot and I had night sights already - it'll do the job. Not gonna win any long distance marksmanship contests w/it, but for up close and dirty, it'll get you on target quick.

I FIND DUTY TRIGGERS WORK IN EXTREME COLD CONDITIONS . I HAVE BEEN LUCKY MY POOR BUILDS WORK FOR YEARS . I HAVE 2 NEW RIFLES I AM TESTING AK AND AR 10 BOTH IN 308 .

Thank you so much for doing this video

As always chocked full of good info! The only place I disagree with you is on the trigger,that is 2stage vs single stage! For home defense, close and dirty work on 2 legged critters in Particular I prefer single stage . I don't need to have my finger on the trigger staging in a super high stress situation! I train more than most! Most don't really train at All!! If were being truthful!! 2 pound trigger pull isn't very much with adrenaline flowing at max capacity! Just saying. Really enjoy your channel Unc. Look forward to seeing your next installment.

If you can get one (and you likely will not be able to), get a Lewis Machine and Tool enhanced Bolt/or enhanced BCG, you can't break them if you try. Sadly these days, impossible to get

Great videos, glad I found your Chanel👍👍🫡

So aero is a suspect company? I bought into the Clint smith James reeves promos! 🤣I like my aero upper on a standard PSA lowe, but I’ve never really had anything that was high quality except my geissele super 42 buffer spring.

SIG AR's seems like they might in the proprietary category.

I've witnessed pins super loose in a dpms, i switched out the trigger for a nickel boron trigger from a saint. Used the exact same pins, but with the new trigger and hammer. That slop was gone. I didn't expect that at all. I thought the slop was from the receiver.

Thank you for sharing this brother. I just ordered my 1st stripped lower to throw together.

My muzzle break is loud for the shooter. But I'm deaf in my right ear due to a 1911 being discharged 6" from when I was 15, now 61 so I've learned to live with it. But my grandson who is just starting out I built.his ar with a birdcage to push the blast foward. I guess I got really lucky or just made my 80% jig well to match mil.specs. my nickel boron 2 stage is crisp, I also polished the crap out of all contact points. Great vid and I'll have to catch up on the others. Been off line for a while. Stay safe out there too.

Very good information, Good job Unc.

Loved seeing those FCD parts. I want to do a ODG build

Larue triggers are hands down the best 2 stage triggers for the money. Great video

Always great info from a fellow HUSKER LANDER…

I enjoyed the information and looking forward to the attachments video.

I’ve been using the 2a armament balios receivers on my last couple of builds. So far they seem to be pretty damn good. And always a rock river 2 stage varmint trigger. Strike industries lower parts. Vltor buffer tube assembly or bcm, faxon barrels, bcm or aero handguards magpul sl stock. Plenty good ambi charging handles. I’ve never really found a bad one. Bcm or rosco bolts but I’ve used faxon and even Anderson in the past with no problems.

Good info. I’ve built a few lowers and I’m glad all the parts I selected were on the suggested list. I use all BCM parts except Radiant charging handle and safety and Geissele triggers.

Wishing the s&w response came with more metal parts!

Interesting I didn't know Nickel boron is like that. I have a question why would it be a problem to use a muzzle brake 556 ? Even though all you have to do is wear electronic ear pro, I understand being in a very tight close space would suck. Some of us live in certain areas sadly where we can on have muzzle brakes.

When you talk about having a spare BCG, how important is it to check the headspace, like on a PSA upper for instance?can I just buy one of those chrome BCGs and put it in or should I have a gunsmith check it. How interchangeable are they? Thanks.

As for the carrier coatings comment idk why you put np3 with nickle boron considering they are not the same at all. Also this whole video is mildy misleading. While staying with good quality proven names such as BCM or Sons of Liberty severely decreases your chances of getting a bad part, it does not eliminate it. Proper gauging and inspection are required always.

Do you have any experience with Windham Weaponry? Quality?

Yeah I had a psa multi cal lower that wouldn’t take any mags besides metal all the polymer mags had to be forced in got rid of that no need to keep shoddy gear it’s not worth the money u save

Which buffer weight do I need on a bcm recoil mitigation system?

The uppers tend to be issue. Almost all of them are not squared. A machinists will be able to square and true up your upper. Ill rock a rock river two stage. Dont need more then that
