This is the 3rd manufacturer of a designated pistol caliber lower I have purchased. The Angstadt 1045 is BY FAR superior to the other 2, and it isn’t even close. The pictures don’t do this lower justice. This lower is built like no other lower I have purchased before. I was sitting at my FFL today and we both were amazed at the beefiness of the 1045 lower. I wish they would include an underneath picture so you can see the width of the trigger guard and understand what I mean by beefiness. I signed for this lower today and immediately did a Form 1 on it. I can’t wait to SBR it when the stamp comes back.

The fit, finish and quality is fantastic! This is by far the best quality 1045 lower on the market. I had many issues with 2 other brands, I’m happy I found Angstadt, they resolved all my issues.

I highly recommend this lower. It’s the only lower I’ve found that will work with a CMMG upper or a CMMG build using their BCG and barrel kit.
It beats having to buy a dedicated CMMG lower when you can save money by buying this stripped lower.

very pleased with the quality, fit finish of the lower is hands down the best dedicated 45 acp AR lower you can buy!

Got to look at it at the FFL, looks awesome. Haven’t taken it home yet, as my ID is in renewal so need to go back with the other form of ID.

I got this lower elsewhere but want to say how satisfied I am with it. It is certainly the key part for a good build. The BHO works every time unlike another brand I have. I costs a bit more but worth it. Thanks.

It’s beautiful! I picked it up yesterday, and assembled it last night. It is the nicest(by far) AR45 lower I’ve looked at, and owned. I grabbed a Frontier after I missed the last stock of these, I’m gonna sell that. Funny, I ordered this from a dentists chair while getting a root canal, wasn’t going to wait, or miss this again…

Paired with a Gibbz Arms side charging upper, Craddock Precision barrel for a 10mm build. Tack driving beast and just waiting for the next hog hunt!!
