I had an SWR Spectre .22 Suppressor which I found to be a very well built an good performing device; on my High Standard Supermatic Trophy Citation, there was no effect on accuracy or POI.
A few months ago I took advantage of SWR's offer to upgrade the baffle system to reduce carbon buildup in the supressor. The new unit was very, very quiet, but I could not hit a target with it. It threw rounds everywhere, but I could not find any evidence of baffle or endcap strikes (I still can't believe this). The only thing that bugged me about the upgraded suppressor was that it would not thread completely onto the barrel, leaving a few thousandths between the rear endcap and the barrel. I couldn't figure it out; there was no obstructiion inside the suppressor touching the front of the barrel when measured with a depth mic. After careful consideration and examination, I decided to run a 1/2 x 28 tap down the rear endcap thinking there might have been a bad thread (it happens, even with CNC). I ran the tap thru to full diameter and removed it, and along with it, a small black rubber o-ring (!).
Long story short, the supressor threaded easily into proper position and now performs with no change in accuracy or POI shift.
My guess is the o-ring was intended to keep carbon from the threads so the can doesn't become "one with the gun', but I use anti-seize compound on all my threaded connections. I'm guessing when I tightend the can down it cause the o ring to bulge into the bore and somehow upset the bullet enough to miss a target at 10 yards but not strike any baffles or the endcap.
This is just an FYI to anyone getting the SpectreII Suppressor. It is not a knock on SWR, more like a learning experience. I love the suppressor and would buy another if I had the choice. Good shooting to all.
