LOWER RECEIVERS QUALITY

[EzGoingKev]

anderson = walking pins... several folks at our club purchased andersons over the last few years going against recommendations. All now have hammer and trigger pins that walk and require a kns pin set to keep them functional.

The hammer pin is retained by the hammer's j spring. The trigger pin is retained by the leg of the hammer spring. How does the lower equal walking pins?

Have any lowers to recommend? Need one more for another build. I have a Noveske Gen 2, PWS Gen 2 and the first Spike's Billet. These have been solid for me.

Noveske Gen2, Aero, Rainier, Mega, BCM, Sionics

If anyone is looking for a Aero precision lower receiver, they have it on sale for only around $45 ($51 if you're in Texas) shipped with coupon code GNA15 on the link above. These usually go for around $80+ with a quick google search. I know the general consensus is the aero precision lowers are GTG.

Seconded on the Mega. I have a forged set so tight I had to use lube on the upper to get it to fit into the lower and both receivers are absolutely immaculate. The fit and finish cannot be beat. I would advise if you like the atomic roll mark to jump on them without hesitation as they will not be producing Mega branded parts anymore but instead transitioning to Zev here shortly.

For the most part, I would agree for a static interaction, but cases can be made using certain less than desirable interactions dynamically that can make that retention less than positive.
