Whats to update. the Magpuls were the ticket for the stacking issue with the heavyweights.

I don't think they do the mileage ratings anymore they have some sort of tread wear rating.

I quit running the BFG's and have run the Nitto Terra Grapplers on two trucks now. I am very pleased with them. Of course I am in the south so ice and snow will remain untested though. Been eying the new Hybrid from them I may try the Ridge Grapplers when I have to put tires on my 4x4 next.

All this waffling back and forth has shot any credibility they ever had.

It seems yesterday I was holding my tiny daughter in my arms. She seemed so small that I could barely hold her without dropping her. Today I have a 1 year old and 3 year old grand sons I am chasing around the house. Time flies but for good and bad it's a wonderful trip, enjoy it.

Only 30 rounds? That thing is not even close to breaking in. I always find a new upper needs a wet bolt and a hundred rounds before I even consider if it has a problem or not. Got to shoot the kinks out first, the bolt needs a bit of break in on all the new finishes.

Either would work depending on what you want. Pistol length would be more flexible with subsonic. Carbine length can be finicky with subsonic. Both work well with supers.

Ragged round holes could mean the bullet shape is just not cutting a clean hole. Keyholes or a oblong shape indicates tumbling. Could you elaborate on what you are getting?

Try one of the small O rings under the extractor to increase tension. You can pick them up off ebay for cheap. If that's not it try a slight hotter load. Could be your gas block is not aligned and you are not getting quite enough gas to completely cycle it.

If you ever get any loads loaded to the original specs instead of the anemic factory loads of today you will regret any lightening. Full power 10mm can be a handful in a light gun. Remember too some of that weight in the slide may be there to delay slide opening, you could be tampering with somethin...
