So long as the suppressor can be removed from the barrel and was not built onto the barrel as a permanent part of the barrel - it doesn't count towards the mandatory barrel length.
So are they ever, actually legal?
I guess what I’m suggesting is that adding a suppressore leaves you with the same length barrel you started with. If it’s too short without a suppressor it’s too short with one, too. That’s the facts as they appear to me (45 years as a mechanical engineer teaches one to think through statements like these rather take them at face value). If you disagree please explain why.
If you move thru enough of the velocity spectrum, youll usually see groups tighten then open, as you go in and out of nodes.Well ... I finished building the rifle AR-10 in 6.5 Creedmore) with the 18” barrel and a Little Bastard muzzle break. Early load development shows an unexpected result (at least to me) result. Surveying the landscape I shot 5-shot groups with H4350 and a 140 grain Hornady Match HPBT with charge weights from 37 to 41 grains in 1 grain increments. In other rifles (and in my expereience) this test usually shows that, as velocity increases so does group size. In this case the most promising group occurred with 38 grains. Obviously I’ll do more exploration but I was surprised that the smallest grouping happened about half way between the minimum and maximum loads in the Hornady manual.
The questioon is: what are y’all’s experience with load develop (faster, up to a point, is better)? Is barrel length part of the story?
Thanks!
I wish I could buy and install a suppressor ... but, like Skyler says ... probably not in Illinois.
