Alberta Tactical Rifle Supply Any Good?

So then does 1 assume you own an AT15 and have made detail comparisons between the 2 makes? To make a blanket statement like you have without having both to compare is rather ridiculous.
How does being a mechanical engineer make any difference apart from adding a degree of arrogance to your post?
Sorry but this is epic fail unless you have something definitive, you are only putting out your "opinion" which are like arm pits, and everyone has a couple.

I had a chance to physically look at a fellow range member's AT15. I guess being an engineer actually helps when understanding tolerances, structures and actual required function.

By the way, did you use finite element method when designing reinforcement structures? It would be great if you could share them, I'd be interested in seeing the added strength, stress and flex point due to the shape. I assume you've tested the standard receivers and know what the weakness is right?

For example:

This test is to similate extreme forces applied due to hard recoil. The light colored locations are the weak points, have you done anything to improve on the standard design? Cause adding more lines on the magwell won't nessecary add strength.

Has your receiver material been hardened? It would be great if they can be age hardened, similar to the process they do to aircraft parts. I believe Vltor uses this method too:

"Each MUR starts as a 7075-T6 aluminum forging that is fully stress relieved, heat treated, age hardened twice and then undergoes a cryogenic treatment." - Vltor website, $206 in US, ~$250 Canada.

What is the type and hardness of your anodizing in terms of Rockwell hardness scale?

All of these inquiries expanded from the question: What improvemets does your design have over traditional designs? From this answer, one can then reasonably judge the price tag.

That's my armpit opinion, I hope it's not epic fail.

Everybody T6 hardens 7075 Alloy, that's what the T6 stands for... Some guys even go on to T651 heat treat it but most of the time it's unnecessary. And adding a Mil Spec lower to Solidworks and doing a stress test on a certain area doesn't mean you engineered the weak points of the design

Man I love engineers sometimes! You're not related to Allan Kerr are you?

Lol I'm not related to Allan Kerr.

Under the lack of technical information, these points were just a starting point for hopefully more in-depth explanation from ATRS. I was hoping it was ATRS responding lol

At no time did we ever claim to have re-engineered the original design. We have taken the plus or minus tolerances out of the equation that were put into place by an engineer so that our products are "on the numbers", something VERY few parts of any sort can lay claim to these days.
And we have enhanced many features from the standard AR15 platforms.
Price is simply arrived at by cost of materials and cost of manufacture. The amount of time we spend hand fitting and finishing increases the cost.
We never intended to be the cheapest nor to appeal to all pocketbooks. Some place value on low production "boutique" articles others prefer mass produced non collectable goods.

We use 7075 T651 alloy as supplied from Alcoa, just as everyone else who uses 7075 to make an AR upper or lower. There are after all only a few manufacturers of this material. We have the parts hard anodized with EXACTLY the same process as does everyone else who uses 7075 alloy in any industry. As an mechanical engineer, you should know that there is a vast difference between anodizing 6061 alloys and 7075 alloys and that billet aluminum COMES hardened and stress relieved.
Google does not require membership, or a ring, you can learn all you need to know about 7075 T651 BILLET material there.
Did you Brinell or Rockwell test the gun you "looked at"? Did you check the tolerances? Oh right you don't have access to those. Was it a Gen 1 Gen 2, Gen 3 or a Gen 4? How many rounds had been through the gun? How many failures to function had it experienced? Was the owner satisfied with product and service?
Having a "look" at something at the range and then making broad and unsupported statements with nothing to back up your blather? Really lame.

We DID engrave a lower for a fellow who asked us to with some artwork he provided that depicted a shield and skeleton key as I recall. We mistakenly assumed it was a family crest. We are NOT in the business of looking up, verifying and learning the significance of each and every crest, logo or bit of artwork that someone want to have engraved on their gun. Apparently this was an insignia of some part of the German military in WW2. We dd NOT know this. The owner of the gun posted photos of the gun here when he got it and a ####te storm rained, the thread was locked before any response could be issued.
On the "other" forum ATRS was banned immediately, therefor not allowing for any response and the haters had a feeding frenzy.

So to set the record straight once and for all, we will NOT engrave anything that we know is offensive like a swastika, we will also NOT engrave crosses, any religious, military moto's crests or symbols or any other form of personalization as a result of this 1 mistake.

So much for the Charter of Rights and Freedoms. I don't understand why you'd get hype for doing what the customer asked you to do on his build. You're responsible for removing material from the receiver, nothing else. My, and the other Rifle Regiments as a matter of fact, use a Maltese Cross for our regimental crests. Am I to understand you'd refuse to engrave our crests into a build because of this nonsense?

That's quite rude actually, I'm not bashing your products at all lol. The quoted post was merely suggesting ways to understand your product. Just answering them is good enough.

Now I understand that there's really no added structural improvements and that you use 7075 T6, and your anodizing is up to spec. I also gather that your tolerance is set at the highest or lowest at various places. These are features of your latest Gen, Alright!

What's with the "lame" comment lol just explain it as if you're explaining to a customer would probably earn you one or two more customers.

So in terms of functions, are there any notable improvements? I see that there's a feature to tighten up tolerance, is this for accuracy? Or is it just for feel?
