Sig Spear LT Owners.... accuracy ? impressions ?

[ansel]

Is it worth the price ?

 

[Near miss]

Probably not. LMT and other AR10s do not leave much to desire.

^^^OP's asking about the LT version, not the large frame Spear.

I've had my 300 Blackout LT since about February. It's robust, feels very solid and it's a tad heavy. Accuracy is fine, I'm not trying to shoot bugholes with this one but it's more than capable. Bit on the gassy side, even with a flow through suppressor. Eats everything including Hornady 190gr. Sub-X rounds which is why for me, she's a keeper. Zero FTF's to date. With a folding stock, it's super compact and easy to transport. The 1:5 twist is not good for normal jacketed supersonic bullets but great with subs. For supers, you'll need monolithics. It's the color of baby poop. Full ambi controls are nice and work intuitively. I would absolutely rely on this gun without question.

Now if you're talking 5.56, I think there's a lot of competition out there. I have a POF P415 SBR and I'd take it over the LT 5.56 SBR. Not as nose heavy, more gas adjustment, likely better barrel and just as robust with a hand guard that doesn't have the LT's issues. Build quality is pretty stellar on the POF and it's not the color of baby poop.

Have you noticed jackets coming apart on supersonics, or do they group erratically compared to monolithic bullets?

 

[Ape_Factory]

I personally haven't had any grenade just yet but I've also avoided using any of the over 1000+ rounds I've loaded using 110 grain projectiles as the muzzle velocity puts them over 300,000 rpm definitely over the manufacturer's stated limit. I also have a similar number of the Speer 125 gr. and they're "borderline" from an rpm standpoint with my MV. I'm a bit hesitant to use them with a suppressor which is my main concern. I've started loading monolithic bullet only from this point forward.

Last time I shot with the Hornady 110gr. V-Max, the holes in paper seemed a bit larger than normal @100 yards. Now if I could get them to consistently frag at 50 yards, we might be on to something fun. I know Frank at Bartlein commented that as the barrel wears, it get harder on the jackets. With varmint type bullets, the jacket is thinner and there's more chance of them coming apart. I do know to avoid the Nosler 110 grain projectiles as there's been documentation of them coming apart with a 1:5 twist and destroying suppressors.

I'm not noticing any erratic groupings. It's a bit easier to achieve higher velocity and accuracy with jacketed lead core bullets. They're a bit more forgiving than monos in my experience. I do have some Hornady 125gr. SST's I need to try out. Just not sure how effective they are at less than 2100fps.

Which flow through suppressor are you using? One from Sig or Huxwrx?

 

[Ape_Factory]

Hux. I currently have a HD-QD762Ti and a Flow 762 in time out. But even if you take the suppressor off, I notice it's a bit gassy. Also shooting at an indoor range this year as it's close to my house but I don't notice it at same range with my other rifles, even with an AR10 DI. The POF is far less gassy than the Sig but two different cartridges/powders.

I also use a standard baffle Diligent Defense Enticer S and it's far more gassy in that configuration but still work perfectly. It's amazingly quiet so I use it with subs where all I can hear is the action cycling. If I were to run and gun outdoors, I'd switch back to the Hux. Huxwrx also has their own HUB adapter coming out (was supposed to be out last month) so it'll make it very easy for me to switch between suppressors.

I do like the BCG actuator rod on the Sig. It's super beefy and triangulated, not a rod. Very robust. I think the piston system itself has proven itself in previous MCX iterations. I've not heard of failures or premature wear in those systems.

 

[Coffee_and_Pipes]

I’ve been interested in the Spear LT as a solid, discreet, travel gun, and I would probably go the pistol route so it could go on out-of-state trips without needing a permission slip. I recently got my HD-QD762 out of jail, so I would be running a similar setup.

I wonder if stepping down to a Rattler and lower muzzle velocities would be a safer option, stability-wise. Otherwise, I would consider the 5.56 Spear LT. I imagine it would be more concussive unsuppressed, and the greater OAL means stowing it in a bigger bag, but 5.56 is cheaper to shoot, and I’m primarily interested in supers across the board.

 

[xxflyingturtlexx]

11.5” 556 since they were first available; over 5000 rounds, mostly imi razorcore and some BH otm. Under moa with good support. Stays clean after several thousand rounds even with a suppressor. I love it. Not for everyone. Most opinions you will find are going to be from ppl who never owned one; and/or doesnt really shoot or train with rifles or simply put can’t afford one.

I use it with a t2, g33, flow k 556 and ngal.

If you have any other questions feel free to ask

 

[Riverlife87]

I like mine, its another rifle. Its not gonna be anything wildly better than a mk18 or something similar buts its cool if you like the idea of a piston rifle. I actually think at the current price its a decent value.

Yep, with the Rattler it'd be far less of a concern as you're just not getting the same velocity. With that said, the 9" LT with monolithic supers is a potent package. Supers in anything short is going to be LOUD. I originally put a muzzle brake on the LT and it was stupid. I wanted to apologize to the shooters on either side of me. Switched to a flash hider and it was no better really. My 12.5" 5.56 isn't any quieter though. I will say the 300 blackout LT kicks a lot more than a 5.56 with supers. Subs, it's a pussycat.

Actually took both to the range today and the Sig, with the Enticer suppressor just about gassed me out after 20 rounds in quick succession. The Flow762 can't get here soon enough. I'd continue using the HD-QD762 but I'm direct threading the Enticer at the moment and until Hux releases their HUB mount, it's one or the other. If I have to fire inside my house, subs with the Enticer isn't going to make the family or pets instantly deaf.

My 14.5” 5.56 used to be pretty annoying when I shot it at the indoor range, and I was doubled on earpro. Now, it doesn’t bother me as much, but shooting it with the can makes a world of difference. I’ve probably crossed some threshold of hearing loss, too.

I shot a buddy’s 11.5” 5.56 outdoors and unsuppressed, and I didn’t care for it. I also didn’t own a suppressor at the time. I had ruled out anything with that short of a barrel, but I’m interested now that I can take the edge off of the concussion.

With all of that in mind, where would you place the LT in relation to some particular 5.56 barrel length? I’ve heard a short 300 blk barrel is not as bad as an equal-length barrel in 5.56.

This would be my first forray into 300 blk, and I’m less interested in the supers/subs back-and-forth option as I am in more muzzle energy (and possibly less blast) out of a shorter barrel. With a twist rate that favors or needs monolithic bullets, that might put shooting the gun outside of my price range as I was hoping to be able to use “cheaper” blaster ammo for practice while keeping some 110 vmax or some kind of 125 for home defense.

 

[Ape_Factory]

I tend to use H110 for 300 supers and it's a faster-burning powder than say H335 which I use for 5.56 supers. H110 is actually a pistol powder and you're using less in a case than in a 5.56 round. There's less powder being burned more quickly and an average consensus on necessary barrel length for 300 black is 8.5-9". Some say certain powders are more quiet than others but I've not been able to discern the difference myself other than noticing Lil' Gun was louder than CFE Black (for subs). I can get pretty good fireballs with the 5.56 out of the suppressor with the first shot. Like impressive flame thrower shit. Subsequent shots don't show any flame and the suppressor doesn't have a built-in flash hider. I don't get that nearly as bad with the 300 blackout, supers and the same suppressor.

So a 300 black super out of a 9" barrel is probably equal to my 12.5" 5.56, maybe even a bit quieter. I pretty much curse anyone who shows up at an indoor range with an SBR and no suppressor. I remember someone showing up at an outdoor range with what looked like a ten. something inch 5.56 and he was two benches down. It was so loud I had to get up and walk away. I don't think I was the only one either as he put it away shortly after and whipped out a .22LR version with a can. I can't fathom shooting one without ears.

There'd be zero point in shooting subs without a can on 300 blackout.

 

[Coffee_and_Pipes]

They’ve released their new Rattler LT, so it will be interesting to give it a few months and see what teething issues it needs to have worked out; hopefully, not that many.

I’d want to pick up a similar 5.56, maybe a Spear LT, as a trainer, but putting extra-gun money toward ammo or reloading equipment is probably more reasonable. Maybe I give up on all of that and buy a couple of BCM pistols, one in .300 and one in 5.56, and call it good. It’s all a daydream for the time being either way.

FWIW

 

[Ape_Factory]

The POF P415 (think it was a gen 3) went more than twice that, also a piston gun, and never really failed. Steel-cased ammo too. I own both the POF and the Sig so no bias on my part.

Nice. I’ve always been impressed by POF and some of the innovation, contrary to many.
IMO anything approaching 1000 rounds is impressive.

I went to an indoor range yesterday and worked on learning hold-overs with my 14.5” BCM. If I started going at a quicker pace (not mag dumps), the gas started kicking up 10-15 rounds in, and it was getting annoying from 20 onward. I’m running a OSS Hx-Qd 7.62 with a carbine buffer and a fixed gas block.

I’m new to suppressors, and I know dealing with gas blowback is worse shooting quickly and shooting inside. That said, how do y’all’s Sigs compare to DI guns in terms of blowback? @Ape_Factory , I know you mentioned the Sig 300 blk runs gassier than your POF, but how does the Sig compare to a DI gun?

This range had LTs for sale, so I looked at their 11.5” 5.56, and the ergonomics, weight, etc., all seemed great, but I want to keep realistic expectations about how the gun runs.

 

[Ape_Factory]

Still have a DI 300 Blackout that's waiting on a new gas block but generally speaking, there's usually more gas with a DI system. I never really noticed the gas with the DI gun but I was mostly shooting outdoors. With that said, "my" Sig is a gassy gun, without a doubt. My only experience is with the 300 Black version however, not with the 5.56 guns.

I have a piston SBR in 5.56 (POF) and a home-built DI 16" and they're both about the same gas wise with the POF producing a bit less. I run the same suppressor you currently have. Indoor ranges tend to trap and magnify the gas too, as does your ammo choice and the powder used. On subs, I'm using CFE Black which is really gassy but it'll cycle any gun and I have a lot of it. My range has walls on either side of the booth and while there's some airflow, it's not a lot so I take that into account too.

But theoretically, a piston gun should have less gas than DI. With a traditional baffle can, it won't matter on either. You'll get a lot of gas.

much love from me. i bought 2. had a couple vitrus and sold them before these came out, too nose heavy

they are a very smooth shooting and accurate. has a cool trigger, like a 1 1/2 stage almost.

they shoot fmj, soft points and mk318 to nearly the same POI at 100yds. so zero with something you like and practice with fmj.

i like piston ar’s but the speer is not in the same realm IMO. ar’s are ar’s because of the bcg/buffer tube. everything else is different. my LWRC IC doesnt get shot nearly as much now and i cleared out a couple DI’s to make room.

are they worth it, depends on you.

i used suppressors on DI and piston AR’s. i never noticed much difference in gas to the face but i’m lefty so i always get that on right handed uppers.

seemed like a waste to put a can on a piston rifle since the blow back gets them filthy and defeats the purpose of the piston upper, IMO
