Anyone have any experience with the PA Drop In quad rails?

Yes. What would you like to know?

How sturdy is it?  How well does it allow heat to vent from the barrel? Ease of installation? Is it a good bargain?

It's very sturdy. No wiggle, no jiggle. Took me about 5 minutes to install. The only thing I didn't really like was the length of the supplied screws was a bit long. IIRC, the originals were 16mm. I swapped them out for some 12mm that sit flush when installed. Be sure to put a drop of blue Loctite on the threads.





As far as heat transfer, it it does get pretty hot under sustained fire. However, installing a VFG or AFG reduces most discomfort. I've used both the Magpul XTM Rail Panels and their ladder rail protectors and I think the XTM does a better job of reducing heat transfer to skin.





Bottom line is I would buy them again. Hope this helps.
