i’ll agree on the Magpul. They make great products but I think their bipod needs a major redesign. Yes, it still resides on my RPR but I went with Atlas on the MPA. Atlas is a much better piece of equipment.
My biggest issue with the Magpul is that you cannot tighten it enough. Literally the rifle will fall over because the bipod is just that loose. The legs are sloppy but On the RPR which has become a practice rifle, I am not going spend a bunch on more accessories. (The barrel is getting very long in the tooth, still shooting well and grouping quite nicely but with around 2200 rounds down the tube, time is getting close for a replacement).
So, back to the subject at hand, got the cash, go at least with Atlas, money strapped, the Harris is a proven product. Don’t forget the adapter.
