Seems like there are not a as many 7.5 blackout barrels as there used to be. I am currently spoiled as I have a 9" MPW that will shoot anything you feed it.
I am looking to make a compact PDW and I am in need of a barrel. I would like to be at the 7.5 inch range but I guess I could go up to 8. I don't want to go past 8". Does anyone make a reliable (with supers and subs) 7.5" anymore and if not how about an 8"?
Thanks!

Re: 7.5" Barrel
The problem with a 7/7.5" barrel is that unsuppressed they are very loud, and most suppressor manufacturers will not warranty their products with barrels under 8". There are a couple, Gemtech has a dedicated 300 blackout can that is good to 7.5".
I have used both lengths and have zero function issues when the rest of the rifle is correctly assembled.

300 Blackout, not just for sub-sonics.
Re: 7.5" Barrel
Heard this from my suppressor manufacturer as well. I had to send one of mine back for a baffle strike and was surprised at their detective skills. I suspect they could tell if you used a 7.5 in barrel.dellet wrote:The problem with a 7/7.5" barrel is that unsuppressed they are very loud, and most suppressor manufacturers will not warranty their products with barrels under 8".

Here is a good read on 300 BLK port sizing and how it relates to reliability in different configurations:

I have an snd6 so barrel lenths I'm looking at are not an issue for warranty.
Re: 7.5" Barrel
The Xcaliber barrels have worked out very well for me. Pretty easy MOA out to 200 yards with a 7". I have the 1/6 twist.themonk wrote:I have an snd6 so barrel lenths I'm looking at are not an issue for warranty.
I know that they have also done some 6 & 6.5" barrels if you're interested in that. Number and email is on the website I linked above, ask for Dustin.
