There are endless options of AR-15 Lower Receivers. Ready Gunner details out the features that you should pay attention to when choosing what lower to use when you build your next (or first) ar15. Shows Spikes Tactical Stripped and Spikes Hellbreaker, Sentinel Firearms, Tegra Arms, Mega Arms, Rock River, LMT (Lewis Machine & Tool) and Aero Precision.

I have to laugh when people say there is a difference between a billet and forged Aluminum have to be forged when Aluminum it self is compounded. Yes it is a compound all Aluminum is forged in it's manufacture process
Your prices are insane.
polymer lower vs. aluminum lower receiver…which one is better and better recomended?
Wrong forged is weaker. The stamping process stresses the metal and creates micro fractures within. Billet doesn't stress the metal since it is machined from solid metal.
Thanks for the info. One suggestion: try to use a table with a darker finish so the camera can have better exposure of the dark receivers.
Like that why they say mel spec
great video…trying to build a AR 47…do i need a special lower for that?
Can you look up the meaning of forged for me and tell me where it says that anything that has been forged comes from any type of a stamps and is stronger? Thank you
AKA Private Labeling the lowers. If I had enough money to buy in bulk. I could call a manufacturer and have the print BADD ASS CO on the side and then pay people to peddle it as the news "cool" around. And there you have it.
There only a couple things people.need to know. Is it mil spec? If not, don't buy. Do you want to get fancy or be a cheap ass? Cause function wise the $300 milspec lower will perform the same as the $49 milspec lower. Also you can mix and match brands from upper to lower, as long as it's milspec!!! This is why everyone only buys milspec and anything that isn't doesn't survive!!!
Does this apply to the AR-10 .308 builds?
There's only about five or six companies out there to actually make lowers so spikes and a bunch of them all made by the same company do some research
Did he say lower parts kit is $250 – $350? That is crazy. Lower parts kits can be had for $25 I can do a mid range drop in trigger and finish out the rest mill spec for around $125.
sorry but you are wrong billiet machined is the stronger. i have seen failure tests and the billet machined are better. BUT ITS REALLY NOT THAT MUCH. FORGED ARE JUST FINE. BILLET IS OVER KILL.
What… Forged is stronger…. Man you fact check your self lolol
Guys, is the lower receiver the only regulated part?
Thanks for the tips and comments between billets an forged made do a lil more research made decide on the forged as for us heat pressure treated it helps th gun durability last longer in my opinion just started this hobby as a beginner
Great video depicting multiple upper and lower receivers, fit and function.
I like how you used "bad" and bad in one paragraph 😛
or just buy a skeletonized one from F1 and pay 3x the price.
Can you use them on a ar pistol
Would you recommend building or buying your first AR? I can think of arguments on both sides
And you have all kinds of options to go with your built.
Unless you're in California.
Like me.
(Tears.)
Billet is better than a “stamped”?? Piece of aluminum. Why would billet cost so much more if it was lower quality?
For all the LEFTIES! : If I buy an ambi. lower, will it not function properly with a regular upper, also mags too?
Not every company makes there own receivers in fact there are 4 major manufactures you can Google this if you want but that so called cheap Anderson receivers well they are the manufacturer that makes spikes tactical receivers and many other companies so pretty much your buying a name look into it you'll be surprised
Everything I have heard and read up to now says that billet receivers are stronger than forged. You say the opposite. I am a mechanical engineer. I have a little knowledge, not a lot, about different manufacturing processes. Forging is shaping material that is heated up to some specific temperature that makes it malleable, with a hammer or a press. So I would assume the forged ones are mostly made to shape with a power hammer or a press with a set of dies in it. Then it is milled the rest of the way to the finished dimensions. The "billet" is a block of either cast or forged aluminum. Then they mill the billet from a block to the specified shape and size. So technically there probably isn't much difference in strength, unless the billet is cast not forged aluminum. The cast billet may have some sections that have misaligned grain structure on the molecular level. That would make it weaker. However a forged billet would have a perfectly aligned grain structure and be just as strong or stronger than a typical forged lower. These are just my thoughts as an engineer.
My lower is solid antimantium, strongest metal in the marvel universe
Billet is alot stronger than forged, somthing made from a solid piece of aluminum is superior to something basically poured into a mold
Just buy an 80% lower
You can make a lower out of aluminum cans
Anderson 7075 Aluminum mil spec lower only $40 at Sportsman's Guide
Or $75 with all the parts installed. https://www.sportsmansguide.com/product/index/anderson-stripped-ar-15-a3-lower-receiver-closed-trigger?a=2094522
I buy rifles for function…i could care less what they look like….same with my car
Anyone who says "tactical reload" should not be taken seriously.
Stay away from polymer, buy forged, stop buying $200 lowers.
I am selling the mechanical parts to convert an RF-31 to CNC for $320. pthomps2@gmail.com

Is it possible to sand/polish the upper and lower so they fit together better if you have a fitment issue?
AR lowers: made of billet or forged aluminum, that's it. Doesn't matter if it's an Anderson or Noveske. They all work the same. So it comes down to do you want to pay $50 or $250.
cant you legally make an ar15 without having to register it
If I buy a complete AR 15 upper with a 7.5in barrel does it have to ship to an FFL?
Why is that Mk18 flipping back and forth?
with both on the same side mag release and bolt release,i think in heated skirmish you are gonna drop your mag accidentally and get shot dead,,,bad idea just saying
Awesome video! Thank you so much for helping a newb like me know a little more on what parts to look in to! Keep up the amazing work on your videos!
Video lost credibility when he said forged was "Stamped out of a block of aluminum". If you're going to make a video claiming to teach others, do your research first. Also, for considering a quality rifle, you'd want to compare both tensile and compressive strength. Compressive strength is traditionally lower than tensile for the same stress. To be honest, even though you threw up some material properties, you really don't know what those numbers are trying to tell you. Don't try to present your guess to others.
Forged is stronger the billet?
That's news to me
Do have to tell you !! I AM TIRED
a heads up for anyone wanting one. a con to founding fathers armory ar1791 lower receiver is that the magpul d60 drum will not fit in the magazine well because of the magazine well angle angles down hitting the lever to load the d60
