I think your confusing the pistol length gas system. The carbine length is fine. It will run a long time with the caveat that it will beat the crap out of your components. A MK18 used to have a port hole of about .080. Mine is .76. It will be fine. 1 Quote Share this post Link to post Share on other sites

Pistol length would increase the dwell time for a 10.5 vs carbine... I belive you need to be careful here and do your homework on Port sizes, a lot of companies open them way up to get reliable cycling Quote Share this post Link to post Share on other sites

ChrisJM981 924 Posted August 27, 2019 11.75" barrels come in mid-length gas. If you have an 11.5" barrel already it might be cheaper to put an A5 buffer system on instead of a barrel swap. I still want to do a second measure on a setup with an 11.5" barrel. It's probably very close though... Quote Share this post Link to post Share on other sites
Krdshrk 3,872 Posted August 27, 2019 Duh yeah - Wasn't thinking - was at work and just tossed out the number.... but yeah 7.5" difference.... And with the brace in position 3 it would be an extra couple inches so what, 5" diff? Still good to me though... I used to be in the "oh it's only a couple inches" camp.. but then after researching and discussing and shooting.... I do want one... lol. Quote Share this post Link to post Share on other sites
High Exposure 5,635 Posted August 27, 2019 I want one too. But I’m not fooling myself thinking I’m saving 9.5” or 7.5” off my typical favorite carbine configuration. I’m going from a 14.5” barrel + muzzle device and a fixed stock to an 11.75” barrel + muzzle device and the ability to collapse a brace. I’m cutting 2.75” and retaining an ability taken for granted in free America. Nothing more. Nothing less. I already have a 16” barreled MSAR (AUG copy) that is shorter overall than my issued 11.5” Colt R0933 Commando. If you are really looking for an SBR substitute with minimal OAL without running afoul of tricky NFA or NJ laws - a bull pup is a solid option. 2 Quote Share this post Link to post Share on other sites
Shane45 807 Posted August 27, 2019 And the attractiveness can really take a nose dive if you have an msar/tavor/aug at around 26.5 with a full 16" barrel! My X95 and my Bren for a length comparison. And the Bren isn't fully extended! 1 Quote Share this post Link to post Share on other sites

I’ve heard a lot of good things about this setup in the AR pistol and SBR threads on Arfcom Quote Share this post Link to post Share on other sites
SMT85 4 Posted September 1, 2019 Does anyone happen to know whether you can change the muzzle device out to a different hider/comp without causing a problems for your self? What i would really like to see is just a basic 14.5 rifle AOW without having to use a brake, pinned stock and keep my bayo lug I would die happy Quote Share this post Link to post Share on other sites

If it’s one of these “non NFA Other weapons”. You can absolutely swap muzzle device, flash hider comp etc as the weapon itself isn’t a rifle and isn’t subject to the “evil feature” clauses. 1 Quote Share this post Link to post Share on other sites

Thank you for the response, would changing muzzle devices on the Troy rifle make the SP letter no longer relevant or would it still apply being its not changing any of the things that keeps it "OTHER"?

As long as you dont put a stock on (prevents it from being a rifle), keep the VFG (meant for 2 handed shooting thus not a pistol), and has an overall length of 26" or greater (not an AOW), you are free to change out what you want 1 Quote Share this post Link to post Share on other sites

Shane45 807 Posted September 7, 2019 I found some documentation on atf site but in each case of making title 2 into title 1, the nfa offending item was disposed of, destroyed or modified into title1. Appreciate whatever you can dig up. Quote Share this post Link to post Share on other sites
PK90 3,569 Posted September 8, 2019 May the short barrel on an SBR or SBS be replaced with a long barrel for hunting or other purposes, with the intent of replacing the short barrel? Yes, and you will not be required to again register the firearm before replacing the short barrel. ATF recommends written notification to the NFA Branch when a firearm’s configuration is permanently changed or removed from the purview of the NFA. If I remove the short barrel from the registered SBR or SBS, is the receiver still subject to NFA transfer and possession regulations? If the possessor retains control over the barrel or other parts required to assemble the SBR or SBS, the firearm would still be subject to NFA transfer and possession regulations. ATF recommends contacting State law enforcement officials to ensure compliance with state and local law. Does the installation of a barrel over 16 inches in length (SBR) or 18 inches in length (SBS) remove the firearm from the purview of the NFA? If so, is this considered a permanent change? Installation of a barrel greater than 16 inches in length (SBR) or 18 inches in length (SBS) will remove the firearm from the purview of the NFA provided the registrant does not maintain control over the parts necessary to reconfigure the firearm as a SBR or SBS. If I remove the short barrel from my SBR or SBS, may I move the firearm across state lines without the submission of ATF Form 5320.20, Application to Transport or to Temporarily Export Certain Firearms? If the registrant retains control over the parts required to assemble the SBR or SBS, the firearm is still be subject to all requirements of the NFA. ATF recommends contacting law enforcement officials in the destination state to ensure compliance with state and local law. Quote Share this post Link to post Share on other sites
Shane45 807 Posted September 9, 2019 Thanks, this info is helpful. As I interpret what you posted, it would seem to me that its not worth it to go SBR until said time you have to. The point in being able to go back and forth would be to travel out of state. But based on your posts, it is indeed still subject to NFA even with the brace back on. So it probably makes the most sense to SBR an alternate lower. Quote Share this post Link to post Share on other sites

If you refer to "retains control", I believe that control is not retained when the stock is left behind in the registered state and you only have possession of a brace in the traveled state.

I’m not a lawyer but I’m going to say yes. Why not? It’s a brace for a brace on the atf list of braces. Mmmm yummy Quote Share this post Link to post Share on other sites
