You do know that the opening on a muzzle break is actually bigger than the opening in the barrel, right? It's just not as large as the opening on most flash supressors. THe fire pig you noted is a weird case as it is a non sound suppressing baffled tube designed specifically to be a flash suppressor. That's the theory. I'd claim it does the opposite. but hey. As for the BCM comp, if you involve science, it's not a flash suppressor. It actually creates some pretty large jets of gas. The larger opening is simply an artifact of assembly. However is the NJSP disagrees, you are going to have to spend some serious time arguing some fery technical stuff about how flash suppressors actually suppress flash and why the BCM doesn't actually do any of that. Based on the design, I would excpext it to produce more flash than a battlecomp or dynacomp. and internet videos of low light side by side comparisons back that up. Given the theorized metrics used, rather than common sense or science, I'd pick something else. It's not cheap enough or perfomant enough to feel bad about skipping it IMO.

QC seems to vary a lot on the tula and wolf pistol primers. In general, there's only three things to vary. Compound sensitivity, stiffness of the primer cup, and velocity change. I use mostly federal and winchester. For the same powder charge, I'd rank them in order of muzzle velocity of the finished round as federal SP, winchester SP, federal SPM, winchester SPM. There's over 50fps muzzle velocity difference between the federal SP and winchester SPM. CCI are quality, but they are a bit harder and a bit flared at the open end. They can take a bit more oomph to seat, and don't play nicely with my vibraprime.

No, but it can be out of spec form the get go. Or the gas block can be. I had issues with that with one gun before the panic buying. The barrel was slightly narrow at the gas block, the hole for the gas tube was slightly oversized. WAy more carbon build up around the barrel though than yours. I keep a spare gas tube in carbine, mid and rifle length around just in case.

The old UMB1 from federal. Period. No idea where to get it at the moment. Normally runs about $10-2 a box of 50. More palatably priced, I found my guns also liked 711B at only about $3-4 a box. wolf match and some eley stuff I tried shot similar, but cost more. I've seen the UMB1 stuf come into stock periodically, but no idea who has any right now, they all seem to be out.

Keep in mind that as wasp spray is a chemical agent rather than a food grade additive, using it in this manner subjects you to greatly increased liability for the injury or death of the person you are using it on. For all practical purposes you should probably consider it lethal force when planning ahead on how to lawyer up and defend your choices in weapon.

Looking at the fiber optic one, this has a sight radius of zero. It is like shooting with a front sight only, except you moved it to the back of the gun so that it is in the absolute worst position to indicate you are deflecting from a proper sight picture, thus encouraging poor accuracy. But since your "good sight picture" is molded in, you pull the trigger regardless of how badly you aimed. Looking at the peephole version, it's a REALLY small ghost ring. It can work, but it will be slow to acquire and settle down to a good sight picture. These are stupid, don't waste your money. Everything that they can encourage that is useful doesn't require them, and there is a bunch of useful stuff a notch and post style sight can do that they will do miserably at.

I had a ton of them.

Yes, we are also jerrymandered to hell and back.

Frangible bullets are a metal powder that is mixed with a binder and sintered. When it fragments, it is into a powder. Shooting steel plates up close, it's like getting pelted in the face with sand. You definitely need eye protection, but it won't penetrate skin.

It is not the only way, it is just a strongly defensible way. You can put yours on with bubblegum if you are comfortable going to court with that. As a purchaser of the stag, you can point at the ffl and stag. Stag can point at the fact they got their method approved during the federal awb. That's a whole different deal than a DIY job.

Yeah, it is addressing overall barrel length. You achieve a compliant overall barrel length by PERMANENTLY ATTACHING a muzzle device. It is a legal guideline on what constitutes a permanent attachment. NJ COULD argue that the BATFE solution is not compliant with NJ law, but they'd have to show you some technical details why, and they don't have any and the law isn't written in a way where they could easily claim that it is entirely forbidden.

Of course not, because slow, low gas ammo won't work badly on a colt after it experiences gas port erosion. Especially in winter. Oh wait.. Marginal ammo is marginal. A marginal gun makes it worse.

My kid is still in the terrible twos. Can't wait until he is old enough to appreciate proper legos.

This is the best part form the robinson arms post "Fourth, if you post a bunch of whiny petty negative stuff here or anywhere, I guaranty very slow service. I have made that a policy. Yes, we've made lots of mistakes with service but that is behind us." They have a funny definition of behind us. I've handled all of 1 XCR. It wasn't a bad design other than the trigger sucked, and there weren't any options to fix that, and it was kind of heavy for what it was. That and the price was high and the wait was long to get one. As for smith, I have a rather unimpressive comp from them, and after seeing the guy bitch about his flash suppressor on the news to try and get it to be the standard suppressor on the m-4 as well as the attitude he threw to the existing customer base that liked their products after changing up their catalog, I grew to basically dislike them. Seems people are rapidly swinging to my way of thinking.

When did you chrono that load? IF the powder is temp sensitive, you may be losing some velocity. Unless you replaced the stock recoil spring with a 13lb spring, you are heading towards the floor of reliable function. Using 165gr jaceketed in my .40, about 115pf was where reliability became very dependant on good form. About 90pf was where you could try all you like, but you were going to get failures at frequent intervals regardless of technique. As others have said, limp wristing could do it, but with the M&P it'll get you whacked in the head with brass unless you are REALLY off usually successful form. However, I wouldn't discount contributing factors making it more sensitive to limp wristing especially with the fairly sudden drop in temps. If you chronoed on a nice high 80s day with the mags in sunlight for a bit, you could have had a nice boost to velocity. I've seen people say n320 is reverse sensitive, normal sensitive, and not particularly sensitive to temp, so you know... something you would have to check yourself. IT could also just be that the trigger didn't break where he expected it to break because of a brain fart, and recoil preparation sent him into full spaz mode. It happens sometimes, even if you have been doing this for a while.

How about you tell me what the required stopping time to make a legal right on red is? Hint it's different in different municipalities, and it isn't consistent nor usually does it remain what it was once the cameras are installed. I've met few to no people who deliberately run a hard red.

The pmc bronze ammo is marginal in terms of gas. An example chronoed the same day, same 16" midlength bcm barrel. Federal xm193 average 3059 fps. Wolf 55gr fmj averaged 2832 fps. Pmc bronze averaged 2654 fps. If your gun has any issues with the gas system that look like under gassing, pmc bronze will show it. It's about the same velocity as wolf 62gr.

The issue with cleaning is that brass cased ammo can get stuck on the fouling that gets past the case because it doesn't deal the chamber as well. I haven't experienced it with a chrome lined 5.56 chamber swapping back and forth, but i know of at least one person with a stainless wylde chamber barrel that swapped between wolf and some Indian surplus with soft brass. It's jam up every time and the extractor would rip off a chunk of case rim. Bad, bad juju in a life or death situation. There's no reason to take that risk when it's easy to avoid it with some cleaning.

The damn thing is 79% windows by surface area. Why is this being taken even theoretically seriously by anyone.

That's not all. The inside of the birdcage style comp isn't star shaped like an a2 flash suppressor. That is done so it maximizes the surface area that the hit gasses are exposed to which helps reduce the temp and thus the brightness of the gas. The comp also only has slots on the top half of the muzzle d

When they were using copper jacketed projectiles I loved it. With copper washed steel projectiles, I don't.

Some of the q-see systems at Costco have the ability to add triggering devices to a couple of the feeds. From a budget minded perspective, a cheapish base is kind of consumable. The bundled cameras are not awesome, and most promise 40ft of night vision and deliver less. A reasonably capable base station can be had for a reasonable price if you shop around and catch a sale. Judicious purchase of quality cameras where needed can help control cost. Running a dedicated 12v power supply and routing cables well makes it possible to keep a frankenstein system going. You get what you pay for is mostly true, but none of these guys design the guts. Most don't even design the software. Add to that a lot of middlemen, and there's money to be saved. I wouldn't save that money at harbor freight. Costco does steeply discount certain models if more established names from time to time. The wired cameras are very standardized and mostly bundle up commodity components. There's a lot of price shopping to be done there.

You can read into it all you want. Hint: the first bush already did what you are concerned about. They have to come in under sporting purposes tests anyway. They don't necessarily come in the way you buy them as is.

Yeah but when you went there was it 85+ outside, hot as hell in there and some really fat old dude just drop a duce in the can that should ahve been declared a war crime? Cause that really makes the looping crap video and annoying speakers so much more enjoyable.

Now now, that's being nice. You ask for his name, and then ask him if he is an LEO or just impersonating one. Then tell him he is free to inspect them, but that you need his contact information in case actual police ever did find them to not be compliant, he could be sued for his ensuing professional legal advice.
