Lol brought to you by crippling debt. I felt that 😂

@Wade-1 18 дней назад

Military does use the Rattler, and I'm sure they use the 5.56 in some units. I know SAS and other elite groups have used the LT.

@markhurley3242 10 месяцев назад

Just stumbled upon your vids, couple of observations from my own experience. The button head torx screws for the forend will easily strip out if you torque them to 45 inch lbs., don't remove the flat head torx screws holding the retainer tab on the bottom of the forend, and finally, my Gisselle reaction rod does not fit the chamber on these guns. I had to ship my upper back to Sig to remove and replace the stripped torx screws on the forend and also asked them to remove the muzzle device as I run a DeadAir Sandman S. Customer service was great, they covered all shipping and turn around time was 4 days. They told me they have received bent and mangled receivers from customers who tried to remove the muzzle device without the proper tools.

@shootloadrepeat 10 месяцев назад

Thanks for the information which is sorely needed. I have not yet tried to do anything with the muzzle device, and will look into sending to Sig for removal although I do have a dedicated barrel vice I could use to clamp down the barrel outside the receiver. Good to know on the handguard screws as well. Thanks for watching and for the useful info.

@shootloadrepeat 8 месяцев назад

Little update. I removed the muzzle device by clamping the barrel (removed from upper and also removed the oprod to give me more room) in a dedicated barrel vice. I have bushings that enabled me to spin off the flash hider with a 3/4 socket and a few whacks with a dead blow hammer. Did not soak in water but if one doesn’t have a barrel vice, water soak is the only option.

@nrocha2466 5 месяцев назад

The reason why so many strip the handguard screws is because they're NOT standard torx t15! They are Torx Plus IP15 screws. Wish Sig would note this !!

@christianbattung2548 2 месяца назад

Sub’d. Going to pick mine up after the cali 10-day wait. Learned so much from your videos!

@rusty9008 Месяц назад

Hello there, any idea how I can block the stock from folding? I live in CA and just purchased a MCX spear LT.

@liggerstuxin1 8 месяцев назад

I got the big brother and want this one too

@shootloadrepeat 8 месяцев назад

Yeah I hear you. I want the big one too but I want it in either 6.8x51 or 6.5 CM

@julianc2789 8 месяцев назад

I found a Sig suppressor for my MCX Spear LT and it is currently in jail! When I had called Sig, they didn’t have any in stock so I’m grateful that I found one.

@shootloadrepeat 8 месяцев назад

Yeah me too. 7.62 but it will suffice. It’s a compact one and titanium so not very quiet we’ll see how it does when it comes out of jail.

@julianc2789 10 месяцев назад

If you want to remove the flash hider I have seen a few guys say they soaked it in hot water which I guess loosen the rock set stuff they put on it.

@shootloadrepeat 10 месяцев назад

Just filed paperwork on a Sig SLH 7.62 compact Ti can. I may leave it on after all. I figure I'll soak in water anyway. I have a 9L heated ultrasonic I can stick the barrel into and then put this in a barrel vise to spin it off if I get antsy waiting a year for approval to come in.

@julianc2789 10 месяцев назад

I filed for one also about a month ago as I found only one place with one in stock so I snatched. Now its the waiting game….lol

@julianc2789 10 месяцев назад

Its the Sig SLH 7.62

@tacticalwave 10 месяцев назад

For me to remove the flash hide I put the tip of the barrel in boiling hot water and held it there for about 5-10 minutes. It was still VERY difficult to twist off I almost ended up breaking my desk with the vise lol. I wish Sig wouldn’t put rock set on all the flash hiders. But anyway really nice video thanks for checking mine out.

@NOLES-kl4ft 8 месяцев назад

Nice set up

@shootloadrepeat 8 месяцев назад

Thanks!

@Boomerfootball1 11 месяцев назад

Can’t go wrong with an mcx. Curious if your gonna do some more of the long range shooting videos.

@shootloadrepeat 11 месяцев назад

Yes i have some long range videos planned.

@Flashhideronly 7 месяцев назад

Wondering if you ever put the vertical grip farther back to help you use your light. Noticed it was way far forward

@shootloadrepeat 7 месяцев назад

I have since made this into an SBR. The vfg is further back now by necessity.

@renatosureal 6 дней назад

What's your opinion on the STOCK folding INWARDS, not OUTWARDS ? To me, it is a VERY PROBLEMATIC proposition as the stock gets tangled with uniform, equipment, etc. and the shooter needs to open some room between its body in order to deploy it. FN-FAL deploys outwards...

@shootloadrepeat 6 дней назад

@@renatosureal I don’t have ausecase in which that matters too much since I’m not a professional in that sense, but the beauty of the system being modular jeans that you can indeed get a stock that collapses inward like an MP5 but you have to buy that stock, or outwards to the right by just flipping the folding mechanics around.

@julianc2789 10 месяцев назад

I’m in Texas…DFW area and bought that gun back in June….haven’t been to range yet because of the Dang heat.! I bought the retention piece recently but waiting until I get the gun out and shoot it first. What part of Texas are you living in?

@shootloadrepeat 10 месяцев назад

I'm just North of Houston. Yeah I hear you about the heat. I've had 110 degree range days shortly after. It's brutal. Hope you get to shoot yours soon. Thanks for watching.

@MaciejLewinski 8 месяцев назад

Do you also feel a looseness between the upper and lower? Especially when you pull the gun towards you in the shooting position?

@shootloadrepeat 8 месяцев назад

No looseness here at all. Actually quite tight. These receivers come shipped with an installed Accu-Wedge which tightens up the 2 halves.

@renatosureal 6 дней назад

How come AR's platform has not been able to ABBOLISH this FORWARD ASSIST button once and for all ?! It is the only rifle which has it ... Is it possible to get RID OF IT ??

@shootloadrepeat 6 дней назад

@@renatosureal yes it is modular and can be changed it for a flush cover that doesn’t have it. It’s there because of a military/contract requirement.

@christianbattung2548 2 месяца назад

Question, the part that holds the bolt catch just needs to be punched out right? Its not threaded?

@MrFra1ler 11 месяцев назад

any more barrel flex issues? I have the 9” 300blk. Mine doesn’t seem to have the issue, but I’m concerned been seeing this all over the place.

@shootloadrepeat 11 месяцев назад

I believe in my case it was mostly if not all, the handguard flexing and not the barrel, as I took it on a range trip and put over 300 rounds through it in quick succession. I stuck it in a case and when i pulled it out at home the. handguard has flexed over to one side. A boresight confirmed the barrel was not affected. I ended up installing the Arisaka zero retention clamp and it really stiffened the entire thing up. In your case the 9” barrel and shorter handguard will have a much smaller lever moment so the issue should be less apparent. Will see over time if it happens again but will confirm zero next time I’m out just in case.

@MrFra1ler 11 месяцев назад

@@shootloadrepeat thanks! I appreciate it

@christianbattung2548 2 месяца назад

Sub’d! Thank you very much for your videos! Learned so much from them! By the way, I have an opportunity of grabbing an LWRC SPR or a MCX Spear LT. Any thoughts to which one you would pick?

@shootloadrepeat 2 месяца назад

Thanks for the sub! As far as which one? LWRC is generally higher quality, but if you want something that is different and not just another AR, get the SIG. I have LWRC also and it’s been great.

@christianbattung2548 2 месяца назад

Okay got it! Just in a dilema since the price and condition of both are similar. Im planning on using it for 3 gun/ multigun. Cant go wrong with either one?

@christianbattung2548 2 месяца назад

@@shootloadrepeat quick question, i was trying to do a function check of the spear lower with the upper removed. The safety on the semi postion and the trigger wasnt pulling. Is that normal since the upper is off?

@vietnamtactical 4 месяца назад

Are you able to use the BUIS when you have a riser?

@shootloadrepeat 2 месяца назад

Yes but just barely. It's not lower thirds, more like lower 7/8ths lol

@jbdoingjbstuff 8 месяцев назад

What size Torx do I nee for the handguard and barrel screws?

@shootloadrepeat 7 месяцев назад

You probably already have your answer but it's T15@ 35in-lbs for the handguard retention screws and T27 @60in-lbs for the barrel clamp. Torx of course.

@nrocha2466 5 месяцев назад

The handguard screws are NOT standard torx t15, they are Torx plus IP 15. This is why so many strip the srews! Wish Sig noted this. Not sure on the Barrel screws...but I suspect the same ??

@Nom_AnorVSJedi 11 месяцев назад

Do you think SIG will release the MCX Raptor soon?

@shootloadrepeat 11 месяцев назад

Haven’t heard of the raptor but if it’s anything like the current rattler then I will try to get one. I’m debating on SBR’ing this one and getting the 11.5 barrel as that is more my preference. Thanks for watching

@nathancdm4 11 месяцев назад

What sling are you using?

@shootloadrepeat 11 месяцев назад

I was using the Blue Force Gear Vickers Sling (Combat Applications Sling) This one: www.blueforcegear.com/vickers-one-sling But I just set up and will use Edgar Sherman ESD sling here: www.weaponoutfitters.com/edgar-sherman-design-sling.html I've been using the BFG slings for years, but I like how compact sleek the Edgar Sherman ones are. Will give them a try actually tomorrow. Thanks for watching.

@victorcastillo8974 4 месяца назад

What stock is that ?

@shootloadrepeat 4 месяца назад

In this video it's just the standard Sig stock that comes with the rifle versions. I'm now running JMAC customs wire stocks and skeletonized bars interchangeably.

@Flashhideronly 8 месяцев назад

You put your front iron sight on backwards 😅😅😅😅
