It looks like they sent you a multi chassis. https://www.AR15.Com/media/mediaFiles/424008/multi_chassis-453811.JPG The one I bought was this one. In the notes I put Subsonic Standard Chassis for SBR build. They are good guys and will make it right. Here is mine. I have no way of conforming that everything will work like planned. My host receiver is a rifle and no 4.5" barrel yet. I explained what I was doing to PMACA and gave him pics of another members build on here with measurements of my cans. And the chassis received was what they determined would work. |

Does anyone here have the PMACA long nose chassis? I have been thinking about a build for a long time now. I just dont know how it would look. Thanks to @HK_DUDE i know what it would look like with the standard multi chassis and a 10 inch barrel, but i want to know what it would look like with a 10 inch barrel and the long nose chassis.
Also, does anyone know what one of the better 1-9 twist barrels without fluting is, or one that is only 10 inches long? It seems like i cant find one that short and most of the normal rifle length versions arw fluted so it would look weird if it was shortend. |

Ok, so once again, you are all jerks. Over the weekend I have spent what... five or six bills on building one of these cool little buggers? Thank Jebus my buddy has a shop and sold me a Charger at five bucks over cost, because tonight I had a couple of beers and ordered a suppressor standard chassis (they have two left btw), a KAK tailhook tube, a folder piece, and a Tailhook. This is going to be my most expensive "mess around" project in ages and I LOVE IT!
Now just have to find a 4.5 barrel because I want a bull, a hand stop and a sight. |

So now that I have the chassis and brace assembly in the way along with a couple if different folder adapters to test, I am rethinking barrel length foe this build. I realize the current consensus is that the 4.5 is where it is at for reliable bulk pack subsonic, however I'm really mulling over the reliability factor with thst length versus a six incher.
Kidd makes a stock six inch threaded bull that looks pretty slick, I realize this will make most bulk pack go supersonic, but I have to think this may also be a little more reliable for consistency in cycling. |

I tested my 4.5" build with Automatch, Blazer 22's and Wincheser 333's without a suppressor and without using a magazine, since the magazine has an ejector and the 10/22's ejector is further back than the mag's one. Casings were ejecting just fine. If you ever did find cycling issues Kidd makes a reduced power recoil spring. It's pretty cool to have bulk pack 40gr turn to what essentially is standard velocity ammo without having to seek it out or pay extra. |

I did SBR paperwork on a 10/22 last year, I just need to turn it into a sbr now. I think I'm going to buy a charger pistol, and swap the sbr receiver into it, then drop it into this chassis, and add a folding stock to it.
these look pretty sweet ! 
my biggest problem right now is determining the barrel length, I'm not sure I want to go with a 3-4" barrel, thinking of staying with the 8" barrel, maybe using the long chassis.. hmm... gonna need to look at a lot more pictures and figure this out. |

Hey guys, yet ANOTHER question! See several pictures with handstops that look directly bolted up with the chassis, are the chassis screw positions the same as MLOK components? I know NOTHING about mlok but it seems thst would be an easy solution if one could just take the rail piece off and direct screw an mlok piece on...

HV ammo is definitely better, but it seems like you figured that out with the AE ammo. Although I can shoot CCI SV with near-100% reliability, my normal range ammo is the Remington 525 pack. The golden bullets are dirty but they make mine run like a top. As an added bonus, HV ammo is still subsonic out of a 4.5" barrel. That'll be a nice perk with the suppressor on there. 2. Just go ahead and buy an aftermarket extractor. They're like $20 and will save you lots of headaches trying to pry brass out of the chamber. I think I've got Volquartsen extractors in all of my Ruger MK series pistols and 10/22s. Even with the match chamber on my Beyer Barrel I still have 100% extraction. 3. If you're still having light strikes, try out the Volquartsen aftermarket firing pin. It may seem like snake oil, but it does make a difference. A buddy has done extensive testing on Rugers to try to get the most reliable firing pin strike, and he advised me to just buy the VQ option as an out of the box solution. Sure enough, my failure to fire issues with some ammo went away upon installation. 4. None of my autoloaders will run Aguila SV at all. I just tossed it in a box to run through my bolt guns. I don't know what it is, but I figured it wasn't worth the trouble to mess with it. |

That new SB brace looks good. Are the "wings" pretty firm? If it wqs to contact your shoulder, would they stay stiff or bend?
Personally, I would shorten the rear of the tube until the front of the rubber brace met the castle nut. That's juat me though. Looks good man! |

Thanks. Couldn't find one of those tailhook things in stock so I went with this one.
If it happens to touch the shoulder and the end of the tube isn't in your shoulder pocket it is slightly flexy. End of tube making contact to your body and it doesn't get to flex. I'm going to track down a shorter buffer tube to cut the length down. The Spikes tube plus the folding adapter adds mucho length.
EDIT: Found a shorter pistol tube in the parts box. The brace sits flush with the castle nut now. That took an easy 2 inches out of LOP.  It'll end up being slightly under 13" LOP.
