I've contemplated buying that PSA BCG/CH combo (w/ 8620 bolt) for $170.
Is it the best of the best? Nope. Is it quality, solid, good enough, better than a lot of what's out there, and probably as good as most folks actually need? Yep. I think it's good quality, great for builders, excellent for those on a budget, and also a fine option for those who want a quality backup BCH/CH at a fair price.
The only problem is that I don't have any need for it at the moment (have two extras each of BCM bcg and ch at the moment), which seems an okay problem to have. But my opinion is this PSA package is a solid buy.
