Sig Sauer Rattler LT (new version) vs Sig Rattler (old version)

lets check out the main differences between the new sig Sauer rattler lt and the original sig rattler.

[@joearabia5627]

Something I think you left out is the barrel/handguard compatibility. The OG Rattler was proprietary in its operating system and handguard. The Rattler LT is updated to be compatible with all other models of Spear LT.

[@thegatmann]

Great info! Pinned.

[@joearabia5627]

And for anyone wanting more info, this means you can't take a Virtus(or Spear LT) handguard and just throw it on an OG Rattler upper. You'd be left with an open gap in your top rail. Trying to add a longer barrel to your OG Rattler will force you to get a Virtus or Spear LT BCG since the operating rods are also different lengths. So, anyone with an OG Rattler has to go through a lot more steps to convert their gun to a longer barrel version. The new LT Rattler is essentially just the Tac Ops version of the Gen2 MCX without the SD handguard, and this change just makes the new Rattler more compatible/modular.

[@jeffkashat4625]

Just waiting on the SD Handguard now.

[@user-ie9jz8ht6c]

According to this comment, The Canebrake handguard for OG Rattler is not compatible with the Rattler LT. Does that correct?

[@ExileXCross]

​@@user-ie9jz8ht6cwithout modification, you have to Dremel off a part of the top rail.

[@DoaneTactical]

Two is one, One is none. At least that's the excuse I'm giving myself to purchase the Rattler LT. I also have an original rattler and love just about everything about it. I like the new receiver features on the new MCX/ Spear rifles so I appreciate them being added to the Rattler LT. Also the compatibility with the other LT models is kind of cool in my opinion. I found myself wanting that with the original Rattler because of the pistol brace fiasco.

[@khtrucking6962]

Great review man thank you!

[@ms542]

FYI: I did boil water then took it off the stove and let the muzzle set in the hot water for 1 hour. However, when I got my muzzle device off on the rattler LT I saw no indication of rocksett. I believe the taper is just really solid and they crank it down at the factory. Easiest way is to remove barrel and put in vise against the sides of the gas block. Use a bit of heat/torch evenly and then use a crescent wrench. Went pretty easy if you have a solid vise and some heat. It did take a few heating cycles with me trying to loosen in between heating.

[@thegatmann]

I’ll try that!

[@criticalstruggle3428]

Plus 1 for my rattler LT. It didn't have rockset I just used a socket and my impact driver. It came right off

[@festerofest4374]

Someone from Sig (I'm in NH not far from their main store) told me they don't use Rocksett. People think Sig does because they are on there so incredibly tight.

[@RedEarthRider]

I now own more sig spears than ar15's. The best way to take off the muzzle device is buying a Gieselle reaction rod. Grinding off the 1 and 3 o'clock lugs. This will allow it to fit into the mcx/spear series of rifles just like it was made for it. The rod is still able to be used with AR15's. Yeah, it cost about 100 bucks for the reaction rod but the grinding off of the lugs doesn't make it mcx/spear specific, so I say it's a no brainer for those who own both platforms.

[@thegatmann]

I’ll check that out!

[@SavageRiders316]

Soo will they offer an upper Conversion Kit for this one like they did for the original? For those of us who already have an SBR Lower available.

[@fatbackcrowe2448]

I have the 5.5 version and I like it better because it fits the smaller Virtus BP . The extra inch and suppressor FH wouldn't let it fit. I think the actual weight is about the same for both.

[@UltimateEnd0]

I like both tbh

[@Youknowwh0iam]

Does the 5.5 have less recoil? Comparing both with same can?

[@portermaberry5909]

Nice review!!! Just might grab one.

[@Rangergeo85]

Hope you're keeping it

[@matthellcat2494]

Why didn't they put that rattler tag on the spear, but with spear

[@rcg3496]

Did I miss it or did you compare the weights and the cost 🤔

[@BrianKern2121]

This video will probably be a good example of my capital gains loses for 2024 in 300 BLK.....

[@EITFM]

Factory sig three prong muzzle device is not difficult to remove on 300 blk rattler. Clamp the barrel assembly in a a vice and It will come right off with a wrench and a bit of leverage. Only on the 5.56 rattler barrel is the muzzle device really stuck on, because it is attached at the factory with Rokset thread glue because it is not supposed to be removed because sig does not recommend people run that short of a 5.56 barrel suppressed.

[@TYMGhosT]

The muzzle device on the 556 spear lt is literally designed to take a sig silencer 😂

[@EITFM]

@@TYMGhosT not the sbr rattler with 5.5” barrel. The barrel length is the primary difference

[@Richard-wz9uh]

LT is a definite upgrade with ambi controls and compatibility with other LT handguards and barrels but light it is not (Yoda?).

[@echofoxtrotwhiskey1595]

It’s lighter than the OG Rattler.

[@Richard-wz9uh]

@@echofoxtrotwhiskey1595 True. True. Still there are significantly lighter platforms for this barrel length and caliber. I'm being picky I suppose. I really want to see more mainstream companies using better materials liked forged magnesium receivers, titanium small parts, and carbon fiber furniture though. Sure it's expensive now, but if it begins to be manufactured at scale, it won't be expensive forever. Then the whole industry is propelled forward. This isn't even considering the untapped advancements in cartridge technology that is just waiting to be used by mainstream firearms manufacturers at large. That could REALLY propel firearms tech forward. Smaller, lighter guns with lighter ammo that has the same effect as current full size MSRs.

[@adamf.4823]

What is the foregrip on the original rattler here?

[@aftermath2333]

What red dot is that?

[@Jasonz1919]

old school rat looks better

[@user-bj5xr5ju4n]

increasing the barrell length on the new rattler is an admission from sig that 5.5 is too short even for the 300blk. disapoointing but lets rather have that +1 inch if needed than not.

[@echofoxtrotwhiskey1595]

It has nothing to do with 300BLK and everything to do with having more dwell time to work with so it’s not as gassy suppressed.

[@chrisket2981]

Interesting discussion 🍿

[@gabrielraveleau1798]

I like the old rattler more, I find it better looking

[@Shoop...]

My main interest in comparing the two lies in it's ability to effectively manage gas with suppressed 300 blk and more importantly it's ability to switch between subs and supers on the fly. After shooting subs does the gas need to be togled when loading a magazine of supers or have they found a middle ground in their 2 stage gas setting. Beyond that, the 300 blk Rattlers true competitor, in my eyes, is the CMMG Dissent and it appears to handle gas, both sub and super, like a pro. However, I have yet to find a true and full comparison of both platforms and more specifically their gas management and how functional it is to toggle them during use or if it's needed. Thanks for covering the cosmetic fluff though, the Sig website doesn't seem to care enough about it's civilian clients to offer much or any information on the subject.

[@paulbarclay4114]

[@artificialtelemetry]

I like the LT the most. I think it's a redesign and though out much better.

[@bluegunner4719]

Does it have a bendy barrel like the spear rifles?

[@crashdsnowman1]

Barrels don't bend, Retorque the barrel bolts to the new spec...5lbs more than the old spec.

[@MaddieLivingston42069]

Very well done video, my favorite gun is probably my OG Rattler with the 5 inch barrel, I don’t chase women so I’m good sacrificing the extra inch 😂 #SizeMatters

[@BUITACTILE]

What brand of ammo did you run for the rattler mine is having feeding issue

[@ryanleach158]

I wondered the same thing but can it really be the ammo? Running subs without suppressor and on high gas setting the og doesn't push bolt back enough to allow correct feeding.

[@lordhuck2689]

Weight difference?

[@thegatmann]

Without all of the attachments, the rattler lt is 5.1lbs and the older rattler is 5.7lbs.

[@cbrdeathwish]

Only thing I care about is how gassy is the new LT? My 5.5 will choke you out indoors

[@GammaRayTrae]

I think the lt is a major upgrade because if the weight saving, trigger (plus you can use any trigger now), and more mlok points They should have gone with a 7” barrel, I think that’s the sweet spot for 300 black as a do all cqb system

[@DudeManDave]

The new rattler is heavier than the old rattler just an fyi.

[@dadrionrichardson530]

About a pound.

[@not_your_business666]

As for me a 6.75 barrel is a downgrade. The old rattler with a folding stock and K can is easier to conceal in a backpack.

[@chrisket2981]

What’s confusing is the “overall length” according to SIG is 16.5” for the LT vs. 23.5” for the OG 5.5 inch barrel. This cannot be accurate.

[@not_your_business666]

@@chrisket2981 Hmmm I feel like it's 23.5 with a stock.

[@patriotgunner]

The Rattler LT has a 6 & 3/4" barrel not a 6.5" like you said.. Just saying

[@jimrodriguez8047]

I’d buy the SIG LT and Rattler LT if they offered with a slower twist. I prefer to shoot the zippy supersonic 300’s and the 1:5 twist is way too fast. Great for subs and suppression but not 110-125 gr.

[@mattrogers6237]

how so? the rotational energy difference in supers is SUBSTANIAL having the faster barrel. The people who developed the round put it in all their weapons as does sig. 1:5 is what all 300blk barrels should be.

[@jimrodriguez8047]

@@mattrogers6237 110 gr bullets in a 9” barrel run about 2150 fps. With 1:5 fast twist at that velocity, excessive bullet rpm and bullet jacket separation becomes a problem. Bullet rpm for the aforementioned is in the RED at nearly 310,000 rpm..entering solid bullet territory. David Silver, the R&D Chief at AAC that developed the 300 blackout found the most versatile barrel twist for supers and subs to be 1:7 and 1:8..that was the design goal of 300 BO to be capable of doing both. SIG focused on maximizing subs for suppression in the Spear LT hence the 1:5, but to the detriment of supers. If you review Daniel Defense, LWRC, LMT and most other manufacturer offerings, they use 1:7 NOT 1:5. 1:5 is not what AAC intended as you stated. 1:5 is specialized for subs.

[@jimrodriguez8047]

110 gr bullets reach about 2,150 fps out of a 9” barrel. At this velocity and a 1:5 twist, excessive bullet rpm and potential for jacket separation is a possibility. Bullet rpm for the aforementioned is about 310,000 rpm. That’s in the RED, where not all jacketed bullet designs will stay together. David Silver, the AAC R&D Chief that developed the 300 BO, found the most versatile twist for subs and supers is 1:7 and 1:8. The design goal of the cartridge was to be able to shoot both. SIG chose to optimize the Spear LT 300 BO for subs and sound suppression by choosing 1:5, and to the detriment of lightweight supers. If you review manufacturer offerings from LWRC, Daniel Defense, LMT, BCM and others they all use 1:7. 1:5 was not the original AAC twist as you stated and should not be the universal twist either as it’s focused on heavy subs.
