AR15 in 45 ACP

[Afalex1]

Its been interesting. It is such a low pressure round it is pretty finicky about gas setup and and spring rates. Once it runs and Rudy gets the kinks worked out I think it will be great. I had fun shooting it when I used my full power hand loads and it fed reliably. It was just the weaker factory target ammo that it struggled with. We will see....

Good luck on working it out.
What weight bullets? 230 or 185?

 

[Afalex1]

The factory rounds were 230 grain winchester white box. My hand loads are hunters supply 200 grain lead round nose flat point with 7.0 grains of unique and 200 grain hornady xtp with 6.5 grains w231. Both average 1000 fps form the 10" barrel. They would have enough umph to knock down a hog with a neck shot. I'm going to test each bullet on live targets eventually.

I looked at the HiPoint 45 Carbine for just this purpose but just did not pull the trigger...I would think that would be the cheapest way to go 45 and have a proven functioning gun. Did you consider that?

With all the variations out there has anyone tried the mech tech conversion?

[Afalex1]

I went with an ar upper because I already have an sbr lower.

 

[FrankT]

Gotcha, I don't want to give the gooberment money for every piece of equipment I buy so no SBR or suppressor here...besides it is unconstitutional!

 

[Afalex1]

They are govn. bribes in my eyes, but I want to play so I have to pay.

 

[FrankT]

yeah something we should be able to do as a gun owner and no special taxes..On a good note i see the BLM backed down now the Nevada Rancher can go get his cattle.

 

[Afalex1]

That's good news. Lets try tokeep this thread on track though.

I'm in a holding patterning the 45 upper for a while. Macon armory is working out the kinks.

Frank I have a HiPoint 40 cal carbine it run flawless. I had a plastic piece break they are serious about their warranty replaced part no questions asked. It is not a very pretty rifle but gets job done and my daughters loved to shoot it. The reason I bought it. It will not do what Alex is looking achieve.

 

[Itsazonik]

I had looked at a .40 cal but thought if I went that route I would get a 10mm instead. Might be a fun one to go along with my 10mm 1911

 

[Afalex1]

I thought about 10mm but shyed away because ammo can be tough to find. Plus I wanted the biggest piece of lead at subsonic speeds. 10mm is typically supersonic.

 

[Itsazonik]

Yeah, the 45 will do great suppressed. Gives me a reason to buy a 45 suppressor

Alex has a Octane inbound and I have a osprey I am sure he feels like me it is a long time to get. Can't wait should be May maybe or at least June

 

[Afalex1]

I'm looking at may or June too. I had it filed via eforms in January, but the recent shutdown of the system makes me think it will be longer. I know the ATF said they are still approving forms that were already filed, but I think we are heading for a slow down.

Its not a huge deal for the octane 45 cause I'm in a holding pattern for the 45 upper now. It will all come together with time.

My class 3 gun shop did not due. E-forms or I would already have it submitted in September. Very curious to see how you 45 rigs works out. I think there are several of us wait to hear.

I talk with Rudy today. He said he had another 10.5" upper he has tested and is going to send it to me. He also said that he is going to run a 100 rounds through it before he sends it off.

It is a bummer that I had to send the first one back, but Macon Armory has given the utmost customer service through the process. If the new upper runs with the cheap Winchester ammo I'll be one happy customer.

 

[Afalex1]

Macon Armory received my upper yesterday. Rudy said curiosity got the better of him and he just had to figure out why the upper he originally sent me didn't run. Turns out they had a boring bar slip while cutting the feed cone on the barrels. He thought he caught all the goofed up ones, but mine slipped through. It was. 015" out of spec. He also polished the feedramp more and did a little.work to the bolt carrier.

I guess these uppers where designed to run with a carbine buffer that has had the weights removed, but it is not true with mine. Rudy tested it with a no weight buffer and it would fail to eject and misdeed. With a standard weight carbine buffer and spring it ran like a champ for him. I like this because u wonky have to switch buffers when going from my 6.8 sbr upper to this upper.

Rudy is applying some cereakote and shipping it out. I will report back when I feet to test it all myself.

Good news, can't wait till your feet test it out!!
