If SBRs Became Title 1 Firearms, What Would Your Practical Carbine Be...?

[Wake27]

Those were the reports, their barrels are excellent, however I will be a contrarian and say the current gas port size might
be a little undergassed. My 10.3 DD barrels (current gas port size) will not cycle and lock back on weaker .223 ammo with anything heavier than the A5H1 & green sprinco spring combo. So far I have no issues from this, but it will be interesting to see how fast it cycles when my Colt 614 Form 4 clears.

I would agree. AFAIK, the over-gassing complaints were only on MK18s. The DD barrel in my URG-I may be just barely less gassy than my BCM middie, as it will not lock back on M3 PMAGs with an A5-3 and green spring every now and then.

The complaints have been that they were over gassed.

Okay now I'm tracking, thanks.

So does that actually make PCCs more practical in terms of accuracy?

Not what I was saying..... THAT Upper is crap. Not the 12.5" barrel concept.

Pistol caliber carbine, HK MP5 and such.

Got it....... Not my point.... See above

That is my point........ Only the Cloners complained.......

Oh, I completely missed it. Thanks for the clarification. I keep going back and forth between My Colt 6945 and my MP5 as a dedicated HD weapon.

My go to rifle is a suppressed 11.5 with a Daniel Defense barrel. It shoots nicely with or without the can. I have never felt that it was over gassed. Sample size of one but it has been a great barrel.
