Do you really want to be taken seriously? A lot of people on that forum have forgotten more about the AR-15 than people here will ever know. What they say about some AR-15 mfgs is based on what they repeatedly experience during classes, and trust me they go through A LOT. It's normal if most canadian AR-15 owners don't know s**t about parts failure, or just plain and simple quality, our f**king mags are pinned to 5 rounds and most shoot less than 200 rounds a year. THEY shoot thousands of rounds in a matter of days, out of 30 round mags, all day long. That's why they know what they know and say what they say.Yes this is true...
As for RRA from the variances i have seen they seem to not follow the TDP, but all manufactures have there own standards that they adhere too. Other issues that come to mind is i would not see the gas key staked very well and would have to be re-staked after 10,000 or 15,000 rds for example.keep in mind though that many failures i have seen are due to the armorer not keeping up with parts replacement specified in there armorers manual.
The one website that makes me laugh is M4carbine.net at times because they follow what ever Colt's employees say and yet i would say most manufactures have gone beyond the milspec standard in many regards.
I was not impressed with Colt's line of rifles at many times, and i find a lot of die harder mentality push's there product. I would choose KAC,LMT,POF,DD, hell even spikes as well before Colt USA. I have seen several Colts have catastrophic failures, they were older model from early 2000's due to quality control and not meeting there own standard. They do make a good rifle but have shown little innovation as of late in that company..
All in all, I would choose KAC every-time for the most part, due to the fact there customer service is stellar and there is a lot of work put in there guns.
Some mfgs produce an AR-15 that repeatedly fails during classes, and some produce one that NEVER fails. That's where the difference is.
