so you wont be coming over? thats a bit of a drive for you. :-)
just like you can pull up pix of broken polymer lowers i can pull up pix of broken forged ones. its not that hard to do.
did you read about the one in YOUR picture? the guy put a bad buffer tube on it, mismatched buffers and got key strikes in the back where he bottomed it out... he BEAT IT INTO..... it was an UPPER PROBLEM not the fault of the lower... & yet even when admitting it was HIS FAULT... they still sent him a new one. as a note: he also received impact marks in his Aluminum lowers when he ran this combo.
but if you want to go that route then read this thread: Plum crazy composite lower...is it reliable - Page 2
or maybe this one...
Plum Crazy Lowers - Page 6 - Colorado AR-15 Shooters Club Discussion Forums
and heres a forged lower to show it can happen there too.
no one said these are perfect or the only choice in the world, but the likely hood of a regular shooter buying one of these and "wearing them out" is not too high.
im not sure how much more torture testing past the 50BMG upper you could ask out of one of these.
then theres that "free replacement" thing that ive never had offered to me on a forged one.. or even a billet one.
there are things to not like about them: my main complaint on the polymer lowers is the trigger guard area... its too tight & too square.
seriously though bud.. im not exactly a noob in this hobby. im into actually BUILDING guns, not just buying parts & put them together.
look at some of my builds.. ive done 0%, 30%, 60% & dozens of 80% AR's... put out a free plate design several years ago so that people who dont have a mill could do these with a drill press.
