Why would anyone pay $30+ for a 300blk pmag "made by sig" when you could get the exact same mag, literally, for less than $20?

Doesn't work with cmmg banshee uppers, but no where is it mentioned that it will only work with certain 9mm bolts. Waste of time and money. Returning asap.

Got these to easily check brass length before loading. If it supposedly checks for sammi spec and headspace then i should be able to put a piece of brass in the guage and if it's over max case length then it shouldn't fit flush in the guage. But it does.

Loaded ammo or not, it should be verifying the case length because if the brass is over max length then it won't fit in any in spec chamber.

I've put pieces of brass that are 0.01" over max length and they still fit flush in the guage like they're good to go. Anyone that knows anything about loading ammunition knows that 0.01" over is a lot. The difference between most cases min and max length is 0.01". So another 0.01" over max is a lot.

Do not buy these. They're absolutely useless.

Within a few weeks of wearing these the material inside the right boot started coming loose and made it impossible to get my foot out without sticking my hand down the back of the boot to hold the material down to get the boot off. Within another week or so it happened to the left boot too. I can't slide my foot out of either one of these boots, and didn't even get a real months worth of use from them before it happened. $100 seems like a good deal i guess, but the saying is definitely true here... you get what you pay for. Don't buy these. Not unless you want to need another pair within a month. I've bought no name boots in the past that lasted way longer than these for half the price. Pathetic.

Is there a ring when the brightness is up to a certain brightness? Yes. Is it the exact same as on a t2? Yes. For the rds, once you get the brightness up over half way and you're inside you will notice a red ring if the dot isn't positioned perfectly in the center of the window. It's the the same on a t2, but since the t2 has more brightness adjustments it happens at about setting 7 on the t2. If you're outside it's hardly noticable unless you're one that likes the brightness cranked to the max. The optic deserves 5 stars because you're getting aimpoint t2 reliability and durability for less than $500. I also like the push button adjustments. They could be a little more tactile for use with gloves, but it's not that big of a deal imo. The biggest pro (no pun intended) for this optic is the aimpoint durability and reliability for less than $500. That's a win, i don't care who you are.

These are awesome. I've used with 5.56 and 300blk. Started with the want for a compact 300blk sbr that'd fit in my vertex duffle without the need for a folder. A 5" barrel with this buffer system comes out to 18.5" collapsed. Loved it so much that i bought another for a different 300blk build (that I've also ran an 11.5 5.56 upper on as well). The magpul sl-m stocks are made for these buffer tubes. They're a perfect combination. Well worth $125 if you want a really compact rifle without wanting a folding adapter. These are just like the older cqb stocks that cmmg use to put on their 300 banshees. Only difference is that the lwrc uses a flat wire spring. Other than that, the 2 are identical in every way. They're both awesome, but cmmg doesn't make theirs anymore, sadly.

It works, and it is a nice system. That being said, it sucks to spend over $300 (after buying the bolt, cam pin, firing pin, and retainer pin you also need with this kit) only to find out that SA will not warranty this product if you use it with 300blk after opening the package. That should be made very clear up front. I'm still going to use it on this 300blk build because i want to, but if anything happens then I'm just SOL.

It wouldn't cycle subs, even all the way open (18 clicks out), with my set up. But I'm using the lwrc uciw buffer system and dont have any lighter buffer options, and obviously can't use a lighter carrier. I'm sure you could get it to work with a regular buffer setup. Luckily, this build was for supers only. I just wanted to see if it would run subs too. So far so good with supers, and I'm using the bleed off feature.

So it will work with 300blk. Just understand that it says in the packaging that it's not for use with 300blk and they will not warranty it if anything happens while using 300blk. How would they know? I'm not positive. Just felt like you should be aware of this before making the purchase since it's not stated anywhere on this product page.

With this barrel i got multiple failure to feeds per magazine. The rounds would always go nose up into the barrel hood. That was with fmj and defensive ammo. The issues instantly resolved when i put the oem barrel back in.

The finish on these barrels are pretty nice, but who cares if they won't feed.

Don't buy these. They're too expensive to ever have the kind of feeding issues i had.

Enclosed optics really are the only way to go now that they're available for pretty much every gun.

The only negative I've found with the eps is that you'll need to file one of the screws down, at least when using with a glock. I think they should have a shorter screw from the factory for this, but they don't. The screw that goes over the extractor plunger needs to be shortened or it will touch the plunger and not allow the gun to extract. I'm even using an adapter plate on the 43x mos and the screw was still too long. So if you have a slide that uses an actual "k" footprint that allows you to direct mount the eps without a plate then you'll have to shorten the screw even more than i did. It's not hard. I did it in about 5 minutes while taking off a little at a time with a hand file making sure i didn't take off more than necessary so i had as much thread engagement as possible. Again, not hard, just something to keep in mind. Don't just thread the screw in straight out of the box and think you're good to go. Definitely function test your gun after installing.

I guess my 3 star review yesterday was a little hasty. After spending a little more time with them than just a couple pulls after installing, all 3 triggers are off. The first trigger i mentioned in my orginal review is the closest to a match duo, but there is some noticable creep in the second stage before a simi rolling break. The second trigger i mentioned in my orginal review is as bad as i orginally described. It's more milspec than not. The last trigger i mentioned in the orginal review is kind of like the first trigger, but the first stage is a little shorter and the second stage has more creep before a slow rolling break.

I contacted sig this evening. Hopefully I'll hear back from them Tuesday, after the holiday.

I'm not saying to write the match duo off completely. They're an amazing trigger when they're "in spec". I think this was just a bad batch that got through QC. And the the fact that not one of the 3 i just got feels the same as one of the others. That tells me that it's almost definitely a qc issue and not that sig just changed the match duo.

And i was going to just edit my first review, but that's not possible. So i felt like i had to make a second review because that orginal review isn't totally accurate. I've learned my lesson about giving a review too fast.
