Agree - with that barrel, it can be made effective for outdoor use - and it makes CQB even better, if you can keep the FPS right around that acceptable level (350ish).
I know
www.deescustoms.com will be coming out with some silencer + extended tightbore packages soon, and we're handling their Canada distribution and will bring some across when they’re available.
I've already tried out Dee’s 6.01 on a couple of my M4 and M733s and it's mind blowing. I also sent one on up to Randy @ DEA and am awaiting his review.... Dee's tested his 6.01's on a couple GBB's and Mac's and has had great results too – hence the upcoming package release.
Not sure on a release date though...
But as you know, any product that’s manufac'd is going to be way more expensive than a home made setup. I expect a silencer + tightbore package to be around 120 CAD, give or take.
