Bumping this. I'm endeavoring to buy one before the year is out. I've passed over many times, but after doing my first Form 1 for some AR SBR's last week, I want the SG553 I've ogled for many years. I have a 551-A1 and a ton of mags already and spent way too much money on OD Green furniture for it (

Any 922r issues with converting the P553 to SBR? I've heard differing answers and perhaps its because there is no definitive answer.
