The quickest way to add an 1" to your stock length if you are using an A1/A2 extention is the DPMS 1" stock extender, if you can still find one: http://www.midwayusa.com/product/613589/dpms-stock-extender-1-ar-15-aluminum-matte I use this on my race rifle, with a EFX-A1 stock which make the whole thing slightly over A2 length, which I like. I don't know if you can still find this thing, you may have to shop around for it.

Fiber optic front sights don't have the fiber for aiming, but for finding the front sight. You use the fiber do to acquire the front sight and place it somewhere in the rear notch, then you use the outside outline of the front sight as per the usual for the whole equal height equal light thing. In your indoor/dim scenario the fiber sight will only do you so much good, sure it is marginally easier to pick up but you still need to see the outline to accurately aim. On the bright side (see what I did there?) the larger front to rear difference means you will have wider light bars on either side of the front sight which should make it easier to aim in crappy light. PS: yes, there are times where you "aim" just with the fiber, for fast close range stuff, but I feel that is not what you are asking.

Burring is rarely an issue. It is possible but not every likely, you won't know until you look. Most often it is the transition of the trigger bar to plunger and depressing the plunger that people notice. The factory radius is not very forgiving. Polishing that improves the fill a bit and re-profiling it (or buying an aftermarket one) makes the a large difference. Obviously if you have a burr inside the channel, fix that while the plunger is out of the gun, but personally I never seen one on the 4 or so MPs I've messed with. Anything is possible, S&W QA is not exactly legendary.

Assuming that is the only part you had moved around yes. The caveat is that Apex has 2 different sears, the forward set and the standard, and the forward set is supposed to be used with the forward set trigger and the other with the factory trigger. Assuming you are using the same trigger in both you should be fine. If you are talking M2, who the hell knows, he new two part sear is something I have not played with.

Hey guys, stop scaring people with that video. smoothing out the edges of a striker safety is not going to cause any safety issues. In fact the worst you can do is make the gun NOT fire, instead of making it unsafe. The gun in that video was jacked up as it had that safety disabled completely and the sear mangled. Those are completely different conversations from smoothing the transition edge on a plunger. Sure, if someone doesn't know which part does what then maybe they shouldn't muck with it, but not every home project is a "death on the range!!!" waiting to happen.

And I suppose the other factor is that pressure on the lugs does still get exerted before the gas systems comes into play at all, before any gas gets sent out of the barrel. I'm thinking there your best bet is a bolt fitted to the extension maybe, for minimal play?

That is my thinking as well, to a point. You are relieving the pressure on locking logs in the early phases, but the more velocity you impart to the carrier the more stress you will put on the cam pin and bolt in the cam pin area when the rotation starts. Personally I have not seen broken lugs but I've seen broken bolts at the cam pin hole, including one of mine, specially when shooting high pressure rounds, my long range ammo is around 60k according to the load data. For me, I've chosen to go to the new JP bolts that have a reinforcement band around that area, and also go to adjustable gas systems to reduce the pressure in the system.

I accept your purchasing decisions, but I can't respect it. If you don't want to hear what people think of your decisions, then don't share them in a public forum.

Dude, I don't care how you are trying to justify this to yourself, you are supporting fraud. I have ZERO problems with buying cheaper optics for training guns, Primary Arms has made solid business selling various clones for example but they do NOT pretend to be something they are not. I'll support companies honest about what they are doing, Sure, you can make whatever personal purchase decision you want, but don't delude yourself that you are innocent in the knock off business.

Well it is good that you spelled out period twice. The first one made me think of your points harder and the second sold me. No one would use the word twice without being correct, surely not.

I couldn't support companies faking brands. I wouldn't care as much if they put a different label on it. As it is, they are engaged in fraud.

I've left the house without charging handles installed. Twice, once for an AR and once for a shotgun.

OMG Im getting sucked into this absurdity Hi-point sells a ton of C9 and a other junk, what is your point? XD's aren't hipoints, but what the hell does quantity of sold stuff have to do with quality?

You guys are arguing with Ray Ray why exactly? He clearly has not shot most of the guns he lists, or tried to obtain spare parts, or tried to repair them with basic tools, etc etc. He is Ray Ray. He is the sort of person H&Ks marketing is aimed at.

TBH that is federal. They are usually not the price leader or the quality leader. Ammo is still a thing everyone wants if the prices are decent, specially after 8 years of gun sales. The ranges are packed more often then not, that ammo is coming from somewhere.

They are good people

If you disarmed them, and you are now in possession of the firearm and they are not attacking you, I'm pretty sure you are going to jail for hitting them.

Because it is assault and it would land you in jail for good reason.

There are a number of variables at work. The barrel could be awesome but if its fit to the receiver is messy it doesn't matter. You could be a great fit with a crappy barrel. It could be the optics/sights mounts being loose or of questionable quality.

What he said, and I've also seen people AD with them more. Don't know why, maybe the smaller button makes it easier to slip off it under stress or something, but I've seen multiple lefties using it AD'ing during fast reloads. Maybe they just sucked at it, but something to keep in mind.

With half a billion on the table, your share holders will be mad at you if you don't sue someone. Half a billion is not money, it is motive with a universal adapter (to paraphrase a movie)

In the great scheme of things, the lower is cheap. it is also unlikely to ever wear out so you get to reuse it many times if you want and you happen to wear out the moving bits in the upper. You can save $50 on it between bottom dollar and decent, but why?

Nothing anecdotal about it . I have two older generation M&P strikers that got 100% chewed up by the newer Apex block that is needed for their forward set trigger/sear. As in the block did not block anything, you could move the stricker past with finger pressure. If you used a more modern revision of the striker this wasn't an issue (or at least not after 10k rounds and a lot of dryfire, eventually everything wears). And that sear is ALL jacked up.

In my experience you are better off with reflex, because not everyone's eyes works with teh holograms and for some reason lots of the hologram sights historically have not been build very well.

But only 4 idiots would vote to hear a case they don't think they have 5 votes for.
