MWG works good... But is a little delicate... I won't totally endorse it till I have a 1000 rds through it... 500 rds to go...<:-)) Start using the ButlerCreek STEEL Lips first...
WMG... Have ZERRO Warranty... And you don't ever leave it loaded after shooting at the Range because the Belt is Rubber, so you don't want to store it under tension...
ButlerCreek STEEL Lips are the Best for the Money...
Tacticalinc.com is the absolute Best...<:-))
