Stay with at least 5" out there and all is well. I open up gas ports as required when shortening to 17" or 18" I recommend against 16" long barrels on the rifle length gas system. |
I would have Randal do the work you wont be disapointed. |
I don't have any practical experience with suppressors so I can't offer first hand knowledge. I HAVE talked to Denny (GTS) about this and he has EXTENSIVE suppressor and machine gun experience going back a LONG time before AR15's even got mainstream popular. Denny tells me (and I believe) that the length of the suppressor that's added to the barrel almost directly equates to adding the same amount of bore length to the barrel. Now in the case of reflex designs, you gain more barrel length without as much actual measured length. So, the longer the can, the more effective barrel length past the port. Putting a can on a 16" barrel with rifle gas should make it run just fine. |
Since nobody else noticed that you started this thread with your post #1, I'll be the first to say "welcome"... You may or may not know that I specialize in barrel and upper work. That being the case, I can handle all of this for you. I keep PRI gas blocks in stock which are almost identical to Vltor gas blocks, especially if you are going to cover them with an extended handguard system such as a LaRue 13.2 which I also have in-stock. Pricing is listed on my shop services page. Parts can be found on my parts page. You might not have found it yet, but check out my how it works thread that's tacked in the troubleshooting section. |
