Quote HistoryOriginally Posted By Roadblock: This just feels bigger than it needs to be. I really want the SIG Cross Trax stock for my LT. I have a spare Spear locking hinge here just waiting for SIG to sell them as a spare part. I hope they just make them in Coyote too! Hell, I'd probably run the Cross Trax stock on my Spear too! I prefer the skeletonized look over the tube and Magpul stock. That makes one of us. I hated the minimalist. Shot my 20rds to try it out, buffer adapter went right on |

The stock on the Cross Trax looks great! Little longer, that raise hump to get you up to your optic easier without running an angled cheek riser, I can't wait try one on a Spear hinge. |

Ran a carbine course yesterday with my sig. I am very happy with how it performed. No issues at all and the Ambi controls worked great for doing Malfunction drills while moving. The recoil impulse is different than a lot of other guns I have shot. Not sure why but the dynamics of how I shoot and the Sig made it seem easier to get on target quickly for rapid follow up shots. I did take the Minimalist stock off of mine and out the Magpul system that comes on the Full size spear. I really like the SL-K stocks and will be converting most of my SBRs to them.
I really want to get a short upper conversion for my other shorties, but I do have a 10.5 Jakl on hand. Its not the same quality as the sig but its still a fun little rifle. |

I got my MCX LT 9inch in 556 pistol. I shot it 2x now. 75gn GD, M855, M193, Mk318 SOST. All reliable and accurate. Gun is zeroed for GD 75gn. I put a trigger tech trigger and a Holosun SCRS red dot. It's an amazing weapon. It's a really hard gun to find as a pistol. I am teaming it up with a SLX556C-QD suppressor this week

ARP used to do 556 barrels in 5/8 threads. They claimed having more meat at the muzzle thread reduced impact to accuracy from muzzle device torque.
Or something like that. It makes more sense the way they explained it. I'm glad to see this actually. |

People will want spares or eventually to replace shot out barrels. Rattler LT seems to be using the same receiver as the standard Spear-LT. So yes, it'll fit. Just need to get the short handguard. |

Thinking or picking up a 9" 300blk for home defense. If using identical cans, how does it compare to the 5.5" Rattler in concussion/sound with supersonic rounds?

They will meter very close. I metered a 7" DI gun vs. a Rattler and it was within a few dB. Port pop is going to dominate in either case.

If you're running a larger volume can, it's going to be six in one, half a dozen in the other. Your naked ear may notice a tonal difference but there's no way you can quantify the actual difference. I hunt with a 5.5 inch rattler. Sometimes i've got my helmet mounted ear pro on, sometimes i don't. Pick the one you want and just get that. |

Roger that brother. There are so many variables there. Proximity of your child to the round being fired. Size of the room, round used, muzzle velocity etc. I don't think the barrel length difference is going to matter. As long as you get a can that's relatively corked up, you're going to maximize your sound suppression. I still think you should pick the one you want. :) |

Does anyone know if the 5.56 7.75” version rail will work with the 6.75” 300blk barrel? Or does it need to be used with the 6.75” rail version.
Thinking about getting the 5.56 7.75” rattler first then 300blk when they become available since it seem like 300blk barrel be easier to find vs 7.75” 5.56 barrel. |

This is probably a dumb question…guys with the 11.5 barrels, are the handguards 10” or longer? Photos seem to put the end of the handguard right at the muzzle device but with my subpar math skills that doesn’t check out.

Your 11.5" is a chrome lined phosphate barrel and their 16" will be a nitride. I'm curious if these manufacturing differences would potentially impact the accuracy.

We discussed on this forum and Sig Talk, the legacy and virtus really seem to like .223 loads better than 5.56. And at that it tended to not be the heavier ones.
The MCX is really a strange beast in what it looked to eat. |

Barrel in the video seems to have the Nitride shine though. All 11.5 Spear-LT setups are chrome lined/phosphate, per SIG and retailers. Before I parted ways with my 11.5", it didn't seem to care for MK262 from Black Hills. |

Uh I think it has something to do with the poorly designed barrel clamp which allowed the barrel to flex as seen in the video and verified by many others independently. This kills the rifle for me, it is simply too expensive to have both a flexible rail AND barrel. Maybe the CSAW clamp is different? We won't know till they actually get in the hands of someone other than CAG and the SAS. |

All barrels flex when yanked/pushed, this is true for the AR-15 as well as any other barrel out there. Taking set, after flexing, is the issue with the MCX Spear-LT/Spear line and I'm willing to bet that has more to do with the handguard screws than the barrel clamp design. |

The URGI was tested right after with significantly less flex because of how AR 15 barrels seat. Maybe if they compared an LMT we could see if all quick swap barrels flex but I'm willing to bet not. And the handguard flex isn't relevant because they aimed with a scope mounted to the receiver. |

The URGI was tested right after with significantly less flex because of how AR 15 barrels seat. Maybe if they compared an LMT we could see if all quick swap barrels flex but I'm willing to bet not. And the handguard flex isn't relevant because they aimed with a scope mounted to the receiver. Except it DID flex, just didn't flex as much. And I'm not referencing the handguard flexing but rather the screws applying pressure on the barrel. I've tested on a Spear-LT 11.5" that the handguard screws installed hand tight prevents the barrel from being removed. Those two small screws cause enough clamping force to retain the barrel without the barrel clamp screws tightened at all. When the barrel flexes, the handguard screws continue to clamp on the barrel and prevents it from returning to zero. Remove the handguard screws, it returns once pressure is released. I have a LMT 12.5", I'll give their test a go on mine soon. ETA: The barrel flexing has nothing to do with their test groups of accuracy when using the 77 grain IMI. They made it very clear the flex testing was considered a separate test from their accuracy evaluation. |

In order to know if the flex is related to accuracy they would need to use a wide spectrum of ammo. One would hope the accuracy issues and barrel flex aren't independent of each other. |
