Finally got my Magpul trigger guard and when I was putting it on I broke the lower. I even used a wood block to support the damn thing but I guess I hit it wrong and snapped the other side off where the roller pin goes.  Man am i pissed now.

That stinks.  That was the part I worried most about when assembling my lower :(

I've heard that placing a magpul MIAD grip will hide the damage.

You can always buy the "Stark" grip.  It looks like crap but it will cover the area.

super glue Seriously though, why couldn't it be welded then refinished?

I'd just sell it at a loss and buy another one.

I'd just tig that little piece back on with the pin in for alignment...

Hit it with a  TIG welder and touch it up with some aluma-black.

There ought to be a shop around you somewhere that does welding, I would think they could fix it pretty cheap.

7075 has poor weldability.

Use some sort of epoxy and a MagPul MIAD with front strap.

Placed an order with Spikes for a new lower. I will sell the Del Ton Lower when it gets here. I'll be damned  if  I ever do that again

I like to use Craftsman "robogrip" pliers for installing the rollpins (wrap the jaws in electrical tape so you don't mar the finnish).  The jaws stay parallel compared to regular channel locks, and using pliers will apply smooth steady pressure instead of the impacts involved with a punch and hammer.  Much more controlled evolution that way and less chance of screwing something up.

As to welding the tab back on, as already stated 7024 doesn't like to be welded.  Even if the reciever was 6061, keeping things lined up is going to be a pain in the neck, definatly not a beginners type weld job.

I cannot understand how this happens.

I just built my first AR, still waiting on the barrel.  Anyway, I've read a number of these type of threads.  I took my time, secured and supported the lower and had no problems.

As someone who welds AL every day...it would be easier to just reconsrtuct the broken ear and re drill rather than trying to weld the broken piece back on. If you are in GA bring it by my shop and we'll give it a shot. Also the anodizing will have to be removed from the area as it will make welding almost impossible.
