Quote HistoryOriginally Posted By Magsz18: It's a VERY smooth, easy to work trigger. Mine was not six pounds. It was closer to 4.5 or 5.0 lbs. I used my Wheeler gauge and measured 6 lb consistently. It's smooth and easy to use, just not as light or crisp as my LaRue MBT2S, Geissele Super Scar, or Geissele Tavor Pack/Bow. So I went and re-did the testing, tried lubing it and working it as much as possible since it is a brand new lower and I've never fired it. 1st stage is 4 lb, final break at 6 lb. This is a Spear LT made mid October 2023. That first stage is relatively heavy by comparison. But its not gritty or vague, just a bit stiff. I was curious and tested my LaRue MBT2S in an AR15 lower. 1 lb first stage, 3 lb final break. Super light and crisp. I wonder if SIG stiffened up the springs because of some MCX's going full auto |

Quote HistoryOriginally Posted By carbon2329: This is not really a comment on the LT but I was at a recent training class and the guy next to me was using an Spear LT (11.5 / 5.56) with the new sig short suppressor (SLX556C). The clutch-Lock seems very nice. It was a night class.....and that thing was a flame-thrower. I found that interesting...... I found out the SLX556-QD was tested in the TBAC Sound Summit 2023 (https://thunderbeastarms.com/sound/summit2023/) Disregarding the political feud between this test and Jay's Pewscience testing... It shows the SLX 5.56 (which based on the weight listed on that site, is the SLX 556-QD) performing quite well, just behind the Turbo T3 and neck/neck with the Velos. The only selling point on the SLX556-QD for me is the Clutch-Lok mounting that works with the MCX Spear LT's native flash hider. Otherwise the Ventum 762 is what I'm looking to use for my other platforms due to its Bravo mounting. Since I went with a Plan B flash hider on my Spear LT upper, and kept the SIG Clutch-Lok FH on the full Spear LT, that'll be my test plan for the next season. |

I removed the M400 Tread factory trigger, and installed a new LaRue MBT2S. About 1.25 lb first stage, 3.75 lb final break.
The problem is, the hammer now has a slight dent from the firing pin. And I only dry fired maybe a dozen times. I did a search and saw that the SIG and Geissele triggers from 2018 or so had the same issue. The M400 factory trigger in my MCX doesn't have a dent from dry firing. https://www.sigtalk.com/threads/mcx-virtus-geissele-hammer-has-dimples-too.326532/ I have thousands of rounds through my other LaRue MBT2S triggers on AR15s and no dents. |

Figured out why my stock MCX trigger was 6 lb. It's the trigger spring. After cleaning and lubing the stock M400 Tread FCG, it went down to 3.75 lb 1st stage, and 5.5 lb total. However with a lighter trigger spring, it drops to 2 lb for the first stage and 4.5 lb total - but the reset is not very strong at all. Feels odd, like it is hanging until I move my finger away enough. Normally it will push against my finger.

FWIW, according to the rep at SIG CS, they said "... the low profile deflector assembly is discontinued... It will still be manufactured as a contract specific piece but won't be commercially available anymore..."
I was referred to a few different distributors from SIG and they were all sold out with no backorder available. The only place I could find that still had them in stock was Optics Planet. @coregon can you confirm this? |

Many times, when there is a low-demand/yield (in commercial market) product like this, it will be discontinued. Especially if it is built on contract demand only. It keeps the (already intensive) SKU portfolio in check. |

Anyone else have issues with the front takedown pin?
Shipping and quality control seems to be lacking… Ordered and MCX conversion kit upper. Arrived as you can see pictured. Anodizing is worn off in the rear lug. The upper won’t mount on a lower right now since the front takedown pin holes don’t line up. It’s not just tight. There is no way a takedown out fits through. I’ve read about loosening the handguard, etc, but is this common? Should this be going back to Sig? Kind of pissed about the damage before I even got it. Edit: Sig is issuing a label to ship it back and get a replacement. Excellent CS!

He posted on SIG Talk. There were a bunch of people there citing their years of experience with the Virtus not having this issue. When I contacted SIG, they told me to loosen the handguard screws so it'd be easier to insert/remove the pin. Sure enough it worked. With lube and wear, I no longer need to touch the HG screws. I still need to use the chamber flag (or suitable plastic tool) to manually push out the pins but not much force is needed. What's not normal is apparently his upper came in the condition shown in the last photo. He said the box was sealed but the BCG was loose like that. |

They're going to send a replacement. That's great news! Hopefully the new one is better! I would still recommend you grab some Torx Plus bits (TP-10, TP-15, TP-27) to have on hand. And if that front pin is still giving you issues, just loosen/remove the handguard screws like SIG recommended I try. I see on Virtus that their handguards have the same handguard link. However, the Virtus doesn't have the 2 handguard screws so that's why they tend to flex or wiggle. Spear LT added those 2 screws. |

Imma have to eat crow here for a min. A few pages ago I said I was going to pass on the LT and get a 416. Well I did and the 416 is a great rifle, However, I went to my buddy's range and he had a 11.5 spear and let me use it the whole weekend during some training. I was thoroughly impressed with the SIG and we had no issues with zero shift or anything else. It balances a little better than the 416 but ymmv. Shoots insanely flat and zero gas to the face suppressed, I will be buying one soon, kinda holding out for a 10.5 CSAW. My hats off to sig on this one, just when I thought I was done they pull me back in.

The 6.75" "Rattler LT" doesn't make a lot of sense to me. On the old MCX (v2) you could buy a 6.75 barrel and use it. The whole point of the Rattler was to make it as short as possible, hence the shorter rail. The 5.5"'s are still going to provide the absolute smallest package. And BTW I noticed Lipseys had them on sale for about $400 off last week.

Sig rep was at a local shop pushing Spears LTs out at an unbelievable prices.
I picked up 11.5 inch pistol (Form 1 already filed) with Romeo4H for $2226 out the door, plus 100 round of 77grOTM. Plus Sig $200 rebate if rifle and scope purchased together. If you consider all the extras, the Spear by it self was $1400. Not bad. 120 in tax 120 in ammo 400 Romeo 4 200 rebate |

I like the geissele ach on regular ars but noticed they don't offer one for the mcx, I think the sch is too big and gets caught on gear. Plan on using a surefire can / four prong. |

The Geissele and Radian are variants of their ar15 handles and latches. A redesign for the MCX for double latches would likely not make financial sense for them. Sig instead started with a clean sheet design for the MCX handle. It is likely that the single latch will continue to be fine as it has for the previous 50 years. |

I got the Raptor ch, but went back to stock pretty quickly. I like the use of the dual latches, and also I think the Radian handles are bigger than needed since there is no sort of clearance with the forward assist to take into account on the right side as there is on the standard AR upper.
