Its removable and ATRS can put a standard rear pin if you so choose. Wonder if ATRS can put a home depot bolt instead ;) as a takedown option. LoL
It wouldn't make sense to replace it with a standard pin since the receiver design prohibits the upper from pivoting on the pivot pin, which "would be" the whole point of a standard pin to begin with.

You can't fit a Geissele National Match trigger without a AR15 style standard sliding pin. There was no hope in it fitting with the Geissele National Match with the fixed rear pin.
 
The Triggertech adjustable trigger wouldn't fit either until I replaced the fixed rear pin with a KNS takedown pin and filed down a part of the rear housing on the trigger.
 
Like I said... the design of the Sporter prohibits the use of the pivoting function of the AR15, why use one that slides out vs one that is fixed? Doesn't make any sense.
 
I fail to see how replacing the rear pin with another pin of the same diameter makes any sense...

By having a removable rear pin it allows 1 to drop the upper down and miss the big protrusion on the trigger where sliding the upper back does not clear the protrusion.
Hard to describe exactly without you having it, but going with a KNS style pin does allow for easier assembly on some of the odd ball triggers. For most guys this is not an issue.
We have altered the rear pin boss on the upper for the F/A uppers to resolve this.

The rear of the trigger housing hits the pin on the way in,removing the pin allows the trigger to slide all the way in, then when you install the pin it should clear the problem area on the trigger.

And as ATRS has said , they’re removing some matarial from the boot the hook, and everything is good
 
Got it. Nobody had said it was because the hook can't clear the space between the trigger and rear pin when assembling the upper, so I was like WTF? lol
 
I haven't been following what little changes you've made too closely but are you saying that my TT Adaptive triggers will work with the FA uppers without having to use a removable rear pin?

From testing the TT triggers here, yes. I am sure there are still going to be some odd triggers that still won't work "drop in" but we have cut down on that number substantially with this change to the hook boss.
 
Did u contact macdef to tell them you don't like your lower?

Yes. It took them 10 days to respond to my email and the gist of the response was "we're sorry to hear that, let us know if we can help you".

It's an odd way to respond when "send us the receiver set and we'll replace it" is the only acceptable answer.

At that point I gave up on receiving any meaningful customer service and got out the power tools.

Their follow up response when I pointed out how disappointed I was with their product and service was "our cell number is posted on Facebook and Instagram." No offer to replace was made.
 
They are too busy pumping out receivers that are out of spec to deal with customers. They will let their poor stocking dealers deal with the headaches.

Just for clarity, as this thread is in ATRS forum - that rifle above is the SLR, correct?

Don’t want people who are uneducated to jump in, see that post and assume it is ATRS work.

Based on where the serial is (which side) in comparison to the bolt catch - that is ATRS’ competitor, the Maccabee SLR
 
Assembled my SLR receiver today. Overall it went well except I noticed one more thing. There was a fairly significant machining mark in the tabs for the bolt catch roll pin.

The rear tab was gouged quite a bit. This concerned me because these tabs are a known week point. I figured that the gouge had created a line that, combined with the tight roll pin hole, was the perfect week point to possibly split along. Not a good place for something like this.

I tried tapping the roll pin in and could tell that it was going to be very tight so I stopped. This time I wasn't taking any chances. I have some longer than normal drill bits so out came the drill. Not overly thrilled but I think it was the best route to take. Pin then tapped in as it should.

Here's the rifle built. IBI 7.62x39 barrel is going on a MS when it arrives but I couldn't wait till then to try it out.

Final thoughts: Both products are very different from each other, both in design and execution. One was absolutely flawless and assembled without any issues. The other is functional but lacking in the attention to detail department.

I am considering one of these barrels so let’s have a review.
