Hi guys, I was just researching your new piston kit and stumbled across the forum. Things look great. I'm just wondering if the Gas Block needs to be pinned to the barrel(?) or if its held on with allen keys (?) ...pinning to a stainless barrel is a bit nasty sounding for a home tuner like me. A year in and my BioHazard combo are running slick as ever..It was well worth the wait. As always thankyou for bringing such a nice product to the Canadian Market. Those 10.5 Uppers are a great deal too!

I Am Canadian Eh!

New piston kit? Only pistons sold in over a year were the closeout of the old OEM kits (they were pinned, not clamped). Currently ST is not evaluating bringing back a piston system.

I guess its a good thing they didn't have any Carbine length ones in stock then! Welcome to the Canadian market I guess :S
Really odd...I guess they've either been stuck in customs or these are "new" Old stock then.
Thanks for the heads up.
