Jeff O Posted March 29, 2020 Share Posted March 29, 2020 16 " or SBR? What are you guys using? Getting ready to build one. Link to comment
MoRivera Posted March 29, 2020 Share Posted March 29, 2020 To me it's probably more about weight than actual barrel length, with whatever attachments et al to make the 16" OAL. Like I don't mind using a 16" rifled barrel if it isn't a full/govt/soccom profile and heavy. On the other hand I'm not so much into the 4-5" barrels with shrouds to make 16", I want any least some barrel length over a pistol. I have an MBX ultralight barrel with comp which is I believe a 14" barrel and a permanently attached comp to make 16" OAL. That upper swings quite fast and brings the rifle's center of mass back since it's such a light profile. But I guess I guess Ideal for me would be 10.5" barrel and whatever lightweight extension to make the 16, so that's a nice combination of both. Or a carbon-fiber wrapped one. I'm currently waiting to put a lightweight extension on an 8" barrel in a CMMG Radial Delayed Blowback upper, and that may be my main 'gaming' PCC. If I could do an SBR then I probably would go with something built around an 8-10.5" barrel for more run n' gun matches. I don't mind a bit more barrel weight/length for plates and steel knockdown, because I'm generally static and just getting into a 'groove' while blasting away. Link to comment
Jeff O Posted March 29, 2020 Author Share Posted March 29, 2020 So, if I use a 10.5" barrel w a permanent extension (pinned, welded) to make it 16", I could use a rifle lower? Link to comment

Joedirt199 Posted March 29, 2020 Share Posted March 29, 2020 I am running the 8" cmmg with taccom extension and it is pretty accurate with my rmr matchmaker reloads. Didn't matter what powder I was testing it with they were all an 1" at 25 yards with a holosun 510 green. Nice a light setup. Link to comment
Jeff O Posted March 29, 2020 Author Share Posted March 29, 2020 Of course Taccom is out of stock on the extension. I got on their waiting list, when I did that for one of their bolts I got email notifications for 2 years after I had already bought one. Link to comment
Darqusoull13 Posted March 30, 2020 Share Posted March 30, 2020 10.5" uber rifle, can't wait for the next one Link to comment
perttime Posted March 30, 2020 Share Posted March 30, 2020 In my corner of the world, most have been going for 12", or a little over, in IPSC PCC. That is because 30cm is the shortest we can call "rifle". Link to comment

zzt Posted March 30, 2020 Share Posted March 30, 2020 I have both a super light weight 16" barrel with comp and a Wiland USA LLW barrel. The Wiland is a 5.5" rifled barrel with a steel shroud to bring it to 16.1". I prefer the Wiland for several reasons. First, it swings much faster for SCSA transitions. Second, it reduces recoil because you don't get the +200fps you get in the 16" barrel with the same load. Third, it lets me use factory ammo in the 135-144 PF range when I don't want to reload. That power range gives the most controlled dot movement for me. Link to comment
cecil Posted March 30, 2020 Share Posted March 30, 2020 my preference is a short barrel with shroud ... my current PCC has a 5.25" Taccom ULW upper... extremely accurate .... lightning fast target acquisitions and impulses ... i am currently building a Taccom 10/16 barreled PCC .. i shoot 124gr bullets using a 130 PF .. dot stays put..

It's very easy to file ATF form 5320.20 by email. I file it every time I shoot my SBRs in out of state matches and it has taken exactly 1 week for the ATF to respond with approval via email. If you shoot more than one match in the same out of state location, just enter the entire year in the From & To date range boxes. ATF link Link to comment
RickT Posted March 31, 2020 Share Posted March 31, 2020 My wife's PCC with Wiland barrel weighs 5 lbs. without optics. My 8" SBR (CMMG) weighs a bit more, but is much easier to swing than a full 16" barrel with real handguard. The Wiland is a sweet configuration for steel challenge. I'll use the ADM lower on the CMMG for both SC and home defense. Link to comment
StealthyBlagga Posted April 1, 2020 Share Posted April 1, 2020 I own several SBRs, and I started USPSA PCC with a 10" AR9 but I never really got to love it. I prefer a 16" with 15" handguard. It feels the same as my 3-Gun rifle and it seems like I can drive the gun harder and with more precision. Something a little shorter might be as good - say 14" - but I doubt I'd want to go too much shorter. Link to comment
Jeff O Posted April 1, 2020 Author Share Posted April 1, 2020 Decided to go 16" for the same reasons. Link to comment
davsco Posted April 1, 2020 Share Posted April 1, 2020 my jp gmr is 14.5" + the comp to get it to 16". i just built a 9" sbr for fun and pre-filed the .20 forms for a couple of matches over state lines for a one-year time period. Link to comment
robertg5322 Posted April 2, 2020 Share Posted April 2, 2020 Got a 16" barrel that had a few squibs, ruined the last three inches of barrel, but the first 13" was fine. I cut it just after the gas block location (10"), then got some .75" ID lightweight tubing pinned and welded on the end. Effective 10" barrel, but the gun feels so much more controllable. No loss in velocity, so I didn't have to change the load either. Link to comment
Jeff O Posted April 2, 2020 Author Share Posted April 2, 2020 Decided to go with an FM products 10.5 side charger. My only concern was that the folding charger looks awfully close to the muzzle. If so I will add a short barrel extension. Went with their lower too, the LRBHO is, by all reports, the best in the business. I know what you're thinking, don't need LRBHO. In a classifier with a mandatory reload from empty, means the difference between master and expert. Link to comment

MoRivera Posted April 2, 2020 Share Posted April 2, 2020 (edited) That's my only sort of niggle with Taccom, even though I like Tim and really like his products. Some things just seem to disappear or get switched up pretty fast, and when you build a system around them and want an extra...or in my case bend a carbon-wrapped barrel and want to get another...they either may not be in stock or discontinued. And if say you use a Stern magwell adapter with various uppers, and all the Taccom barrels have the feed ramp, then I'd have to mod the Stern adapter, but that won't go with etc other uppers/barrels I use. It's cool that they come out with stuff so quick, but then some things seem to drop off quick too, and you can be left behind. Anyway, this shouldn't be an anti-Taccom thing. Like I said I like Tim and his stuff. Just got to stay on top of it. Edited April 2, 2020 by MoRivera Link to comment
