hump

Thanks. I was leaning towards the 510c due to the size of the glass. I will go ahead and get an Atlas mount on the way.

Is the optic still robust to allow dumping into buckets for 3gun matches?

I am currently running a 507c on my CO gun and really like the clarity of the dot. It is very easy to pick up. I have a Atibal MRD v2 on my open pistol and have considered buying a 510c for my open pistol. I have noticed several for sale in the classified with a mount and have to wonder if the weight is an issue. I would just change the 507c over to the open gun but I will need to buy another mount and don't want to end up with an extra mount if the 507 is to small for the open pistol.

I have been thinking aboit trying a 507 on my open pistol. I really like it on my CO pistol. Does the size of the glass slow you down.

I am shooting 9mm.

I use the Major Pistol with good results. Much cleaner than AA7. I also use the Auto Pistol for major of. It is very similar to HS6

Has anybody else polished the feed ramp on the receiver? I polished mine to a mirror finish and it hand cycles amazingly smooth. The shells almost jump into the barrel. Haven't been to the range yet but it sure feels much smoother.

How effective is the comp when shooting 1145fps ammo. I can't tell much difference. I am going to drill 3 holes in the top of the comp to see what that does but I am thinking I will just leave it off. The pattern is much better without it also.

I have a Lynx and it ran great right out of the box. It has been extensively upgraded with parts from Carolina Shooters Supply.

Me too

Yes shells down

Rotated facing the wrong way.

The RIA mag springs are a LOT stronger than the springs in my 12 and 20rd mags for my Lynx shotgun. I have wondered why they need to be so strong. I did find out during a match on Sat that installing a spring backwards in a 10rds mag will cause misfeeds.

Mine is set up pretty much the same except I am running the factory buffer and spring. I polished the trigger and changed the trigger spring and improved the trigger a lot.

I think I found my problem. The forward legs on the bolt carrier were rubbing the magazine. I measured the carrier legs and found the very front of the leg was .038 narrower than the rear section. I adjusted this and it is now much smoother. I won't get to test it before the match on Saturday but it feels "right" now.
