Quoted: I’ve seen this video before and was impressed. Totally forgot about Delta P. Their website is down, but I sent them an e-mail asking about availability, weight, decibel reduction, blowback/gas flow. Forgot to ask if the direct mount has the taper to the barrel, or if the beveled shim needs to be used. Will inquire about that if I get a response. Can someone recap the specs in the video?

I guess this is just a philosophical difference. I see the logic in wanting a shorter gun to be less loud, and minimizing the length on an already long gun. If anything, this seems like an argument for multiple Sandmen so one can use the same mounts and use whichever suppressor they want at the moment. |

Quoted: I am the exact opposite. If I want a short rifle, it’s because I want a short package, and I don’t want to mess that up with a long can. On the flip side, if I am using a long rifle (which will often be shot prone or otherwise rested), I don’t mind another couple inches of suppressor. I guess this is just a philosophical difference.

View Quote Another factor is I do very little bench shooting. If I'm shooting a long gun, I'm doing it off hand. If I have a huge suppressor on it, it feels more like a lance or a spear than a rifle. Where as a ~10" rifle with a ~6" can just feels like a normal rifle to me. If I'm on a bipod, shooting long range, gimme a huge can, preferably titanium. But in this part of the country, that ain't the norm. My problem is that the Sandman line is kind of the tank/FA rated specialist. Makes no sense in a smaller package, to me. Why get a tiny can that's heavy when you can get a big can that's heavy? To get this back on topic. Got a ton of 300 BLK subs to test through the Rattler, still wishing Sig would make something specifically for it. Also be interested to see a canebrake rail sold separately. The Canebrake trigger has it's own MPN, so I'd imagine the rail will, too. Have to call Sig and ask. |

Quoted: Hey, nothing wrong with that. Different strokes, and all. Interesting to hear from someone on the other side. Typically speaking, shorter guns are louder, shorter cans are louder.

Sig helicopter brace is horrible. It's nice to have options, though. Trying out the tailhook option for a minute in lieu of the SB Tactical offering. Neither of which spin....

I had the opportunity to ask Mike Pappas directly about running the Wolf on a rattler with supers the other day when he was in town at a local silencer dealer. I asked about any issues with the barrel being super short and running supers and he was not concerned about it. He said long term, you will definitely wear the baffles out but it would take a significant length of time with a normal firing schedule and at that point they would happily restack the can for free under warranty. My conversation with him was enough to ease my fears about buying a wolf to do double duty on the rattler and the scorpion.
I do still have my eye out for a sig SRD 762 when they go back on sale to take over as a dedicated rattler can. This thread is keeping me alive as I wait for my rattler to come in. |

Next week will be 8 months in on the wait for my SRD762 for the Rattler...Sigh

Does anyone know if the Rattler "conversion kit" that works with regular AR lowers is a true "drop on" kit or do you have to replace the hammer / trigger with a Sig proprietary part to get it to work?
I was interested in getting one for one of my SBR lowers but I'm not sure I'm keen if I have to replace my trigger group. |

Dealer called, my wolf was backordered. DA stopped making the wolf, is now the wolfman. Wants to know if I want to go that route.
I had my mind made up on the Wolf. Now I find myself second (or third or fourth) guessing it, wondering if I should just but a dedicated can for it. FA762Ks are stupid cheap from arms unlimited, and if the SRD762-QD ever comes back in stock at thesigapp, that would be a good option as well. Reading some earlier posts in this thread from TFB, it sounds like the SIG can may be the way to go. Penny for more thoughts on this. Rattler upper will be here Wednesday |

Another week and a half marks nine months since the check was cashed for my SRD762QD. Hopefully I'll be able to give meaningful input on this topic before too long.

I decided to YOLO and buy one of the Rattler conversion kits, and I plan to install it on a new pistol lower instead of one of my SBR lowers just so I don't have to swap the guts and parts.
Anyone who has one of the conversion Rattlers, did it come with the tapered shoulder adapter for the barrel? Also, does anyone here have one of the Strike Industries braces? Are they any good? |

Quoted: I have the strike industries brace. I would not recommend it. Couple things that irritate me on it, it always has a little wobble/play to it no matter how tight I mount it to the 1913 rail and it is very uncomfortable if you do shoulder it. It is hard plastic with some sharpness to it and I can only shoot it a mag at a time ir so before taking a break. View Quote Is the PSB sort of the defacto "decent" brace for these then? I'm not digging the side folding variations personally, but if they are the superior brace choice then I might have to forgo aesthetics for function. Also, and this possibly doesn't have an answer, but why does it appear the Rattler conversion kits come with sights but the actual complete guns don't? |

You want the wolfman, but maybe not for the rattler if you do a lot of high volume shooting. Dead Air will warranty it, but Nomad or Sandman would be better option if this is the case. Put the wolfman on your MPX.

The answer for me as to the supers vs subs question is going to depend on the ballistics. I can run either the Hornady 110 GMX Barrier or the 190 Sub-X TAP. My guess is that the 110 is going to easily outperform the 190s in intermediate barriers, but the super short barrel muddies the issue in that Hornady can't give me a straight answer either way. Have a few boxes of each on hand to get some numbers, groups, and gelatin data on intermediate barriers.

Quick question for Rattler conversion kit owners: Are the conversion Rattlers compatible with the sliding stocks?
My kit is supposed to be delivered today but the more I look at pictures it looks like the rear section of the AR15 receiver (where the buffer tube installs) possibly blocks the slide channels too much for one of the sliding stocks / braces to install and retract. Every picture I found online of the conversion guns (which are very few and far between compared to the "regular" factory Rattlers) they all have side folding stocks. |
|
Preface: I haven't attempted, just based on my own research into this questions:
The conversion block on a regular AR lower does not allow the use of the HK style stocks. There have been a few folks that modified their lowers to accommodate but I think the general feeling is that too much material is removed in that process to assure the structural integrity of the buffer tube attachment area of a traditional AR lower. |
|
I did it to a poverty pony lower. I'm not planning on buttstroking anyone with the brace, and it's worked fine so far. But, I also have a SBR MCX lower that I put it on more often than the raped poverty pony lower.
If I were doing it again, I'd just wait and get the pivoting contour brace instead. |
|
My kit arrived and now that I have this heckin' chonker in my hands I can confirm that those sliding braces won't work without alteration... and since I'm all thumbs and half a foot when it comes to cutting on stuff, I'm going to just get a side folding brace and be done with it.

OK, another set of Rattler conversion kit questions:
Does anyone else's BHO just completely not work? I took this thing out to shoot it as a test run and while it works, the BHO is completely non-functional. I can't even manually push it in to engage the bolt just slams home. With the receiver off the lower I can see the empty mag pushing the BHO up like normal so it is not a lower or magazine issue. The Rattler's bolt carrier just seemingly won't lock open. Also is it just me or is the finish on this upper one molecule thick? Upper went from the shipping box to my lower then into a padded case to the range and back... and there are tons of little flecks and nicks on it already straight down to the metal. I took the upper off the lower while troubleshooting the BHO and noticed the sides of the receiver pin holes are rubbed to bare metal in spots front and back. I removed the kind of hinkey factory sights just now and there are rail nicks where they were down to bare metal as well. It feels like if I cough too hard on this thing the finish is going to fall right off. |

No, mine works fine. Have you checked the buffer adapter for tightness? Or the rubber recoil buffer?

Quoted:
No, mine works fine. Have you checked the buffer adapter for tightness? Or the rubber recoil buffer? View Quote I can slowly pull back the charging handle while looking in the ejection port and watch as the bolt carrier slides over the BHO and I can see it snap up. Then as the carrier continues backwards the bolt head itself pushes the BHO down again. Then as I slowly release it forward the BHO comes back up after the bolt head passes over it, and I can see the top edge of the BHO just -barely- make contact with the lower leading lip edge of the carrier causing a very noticeable "pause" in forward motion as if it is going to hold... but then the spring pressure and weight of the carrier just shove the BHO back down out of the way and it continues forward. The "problem" appears to be that the normal AR15 BHO in my SBR lower is not riding high enough. I can't get it to angle any higher, even when pressing hard against the bottom of the lever you can feel it is "bottomed out" and it won't rotate any higher in the mechanism. As a "control group" the BHO in this lower works 100% with three different regular AR15 uppers I installed, but with this Rattler upper it refuses to engage. Again, the upper feeds and fires fine with no jams or problems, I put three mags through it to function test it. It is just that the BHO on my SBR lower is completely non-functional with this upper. I'm still waiting for the new lower I ordered specifically for this pistol build so perhaps it's BHO will work, won't know until I get it next week. |

I got my conversion kit in two days ago and it works fine, including BHO. I did find a used MCX lower and bought that, so I am not using a "converted" ar lower. I also don't have the same finish issues.
I do think that this SB brace sucks. Flexes pretty good since there is no metal in the thing at all. Looking for another brace option. Sig sounds likes its a no go due to its helicopter nature, SB is flimsy. Trying to find a different option. May put the buffer tube conversion block on and just get a tailhook on a pistol buffer tube. I don't want to add the width when folded, but it may be the only good option right now. What other pistol braces are there in the world that clamp securely onto a pistol buffer tube, ala the tailhook or doublestar strongarm. Any other ideas? |
