Some highly regarded BCGs have no staking. Staking or not isn't a measure of quality.
FA vs SA carrier weight isn't a measure of quality, either. JP LMOS carriers are lighter-- are they crap?
And with the proper (small diameter) firing pin, is the lack of shrouding really a major problem?
Sure, a premium BCG is worth the modest upgrade price, but the examples you cite hardly make the Ruger BCG "garbage."
Sorry man, it's cost cut hot garbage IMHO.
Using the firing pin to cock the hammer is just stupid. Why in the heck would they do that when there's a shrouded design that uses the carrier. Un-shrouded BCG's are just a dumb design. No thanks. This is a prime example of cost cutting and why you spend the extra $150 for a Colt 6920.
Regarding some premium BCG's lack of staking, I'd assume you're referring to a Youngs BCG. That's a premium BCG. And I still wouldn't trust it. They did some testing and said it was good. However, there's reports of the bolts backing out in training classes when guns are run hard. People staked them after, and they were fine after staking. The lack of decent staking on the Ruger is just flat out manufacturing to a cheap price point and highlights their junk BCG design.
Comparing a JP system to this Ruger is laughable at best. JP has done so much to finely tune their systems. This Ruger is just doing non full mass for cost cutting. I wouldn't use full mass vs. non full mass as a hard and fast decision making rule. However, in this case, it's just an indicator of cost cutting and a POS component.
Fair enough.
My understanding is that unshrouded FP designs originated in the 70s not as a cost cutting measure, but as a workaround for unintentional FA that Colt had to deal with. ATF and all frowning upon FA for a non NFA gun.
Does my new Ruger MPR contain these deficiencies mentioned? I have not shot it yet, and am new to the platform. I havn't even taken it down for inspection yet.

You should just buy an AK. Problem solved. You're welcome.

For the lower, if you only want a great trigger and the rest stock- buy a complete lower and change the trigger. When you factor in labor and whatnot, I don't see you being out money that way.I'm trying to decide if I should buy the tools to assemble an AR or just pay someone to assemble the lower. Also I don't know if I want to just buy a complete upper or buy all the parts to do a full build. Never built an AR before so I' m a tad out of my element here
