Modern Sporter builds Q&A

If anyone else is hella OCD like me, cut 1 strip of hockey tape the same height as the rear lug and wrap it around. It takes up pretty much all of the slop between receivers. It's nice and tight now.

How is the dust cover pin retained without the c clip?

Most Barrel nuts are going to have a large enough diameter that they will keep the pain from sliding forward. In the off chance whatever Beryl that you choose happens to be too small, it's pretty likely that your handguard will do the same job.

can you show us? I've also used hockey tape on my AR's and almost everything else, got a roll in my range bag

Does it seem like a delta ring will be enough to retain the dust cover pin?

Dumb question.. ha ha
But what keeps the pin from removing rearward, if you don’t use a Cclip

ALG Defense rail anti-rotation tabs needed a little filing to work.

The handguard I believe.

It cant. One way in, one way out

 

[BCreserveMP]

The other rearward direction.
I’ve watched vids, where the c clip was removed and the pin was pushed out towards the rear. ( butt stock end)

The rear hole is not machined all the way through. It's more like a socket.

I dont have a way of hosting pictures. Shoot me a PM. I changed it up a little.

It's how a standard AR is designed to retain the pin, so yes.

Thanks!!
I had to change it up a bit. Dont worry too much about overlapping as the sides will sheer off themselves. Just make sure you dont leave pieces inside.

Woo hoo! Final fucaly .., lol
Thanks Dietz

Did you get the trigger filed down so the upper fits?

 

[Dietz]

Wrong person I think. Mine is a a basic single stage mil spec I paid 25 bucks for (though it is actually pretty crisp)

As far as military rifles go, the basic AR15 milspec trigger is an excellent trigger.

Your receivers must be super tight now, since ATRS must be holding pretty small tolerances in the mating areas to begin with. Your tape is putting pressure on the pin itself, and not on the sides of the receiver/hook, correct?

 

[BCreserveMP]

The hockey tape trick makes it even more Canadian.

 

[johnmbrowning]

Gee, is there that much slop compared to your AR15's?

Well my AR has an accuwedge to remove slop, not really an option with this. Dont get me wrong its not out of control i just personally like a rock solid lock up as to not disturb my longer range prone shots.

I’m guessing you’re using a rest, sling, or bipod for your probe shots? The only way you’re going to find the slop in the receivers is if you’re deliberately twisting on it and looking for it.

When you have contact on the upper and lower and there is movement, and you are focusing on a target at 500m you will notice it, dont have to "go looking for it". I already said its not a huge deal, im going to do the hockey tape trick and it should be fine.

 

[Dietz]

If its loose enough to make a rattle sound, then it's too loose IMO....But that's just me. I have OCD like that. I dont own any ARs so I cant really compare it to anything.

It's pretty impossible to not have a rattle sound because the buffer contains loose weights that are meant to be freemoving, and the bolt carrier is floating too.
