Any one ever try an aluminum bolt catch before? I can see it being a disposable part like an aluminum bcg. This place called PAMAX Tactical has some. It's probably the lightest bolt catch there is even though it clearly seems to be a knock off B.A.D bolt catch but made of aluminum. I might try one just to see how durable it is. I wonder how much lighter it is than my moded titanium bolt catch. My guess is that it weighs around 4 grams since my titanium one weighs 6 grams.
https://www.pmtactical.com/product-page/ar15-enhanced-aluminum-bolt-catch-release Can't wait till those incognito arms stocks start shipping, at this rate breaking 3 lbs is guaranteed. I also got my 14.5 barrel back from rainier arms today. I took a couple of quick pics just in case anyone wants to see how their titanium muzzle brake pinning and welding work looks like. https://drive.google.com/drive/folders/1ea0OQqRcmIf0cBWowkiuZNPFKfXKjTc_ |

The entire plum crazy parts kit comes in at 126 grams. Trigger group is 17 grams. Takedown and pivot pins 3 grams. Magazine catch with spring is 3.5ish grams. Magazine catch button and bolt catch detent according to my scale TOGETHER are 0 grams, rofl. I need a better scale... Safety selector is 3 grams. Pretty light stuff!!! And the hammer is identical to the one new frontier sent me out as a replacement. All these parts look and feel different than the old school NFA polymer parts. They do feel like they are higher quality.

I went with sharps because they use a much harder steel than the others. When they first came out they had bolt breakages but it was a heat treating issue. I believe you will be happy with the iron city bolt though, it appears to be high quality. I put more even more money into my "duty" guns than my lightweights, i like to throw every dollar i can at attaining reliability. Spikes tactical makes ion bonded gas rings too, they are a great product. They started making them because their "compressor" SBR was eating up regular gas rings in only a few thousand rounds. The ion bonded gas rings lasted as long as the 7.5 in FN doubled chrome, cold hammer forged barrels. View Quote |

A bit of light reading on each coating shows both have similar lubricity, and both are "corrosion resistant," although I haven't seen any info comparing one to the other yet. DLC is much harder, and much thinner than NP3, at only a couple microns, so I imagine there isn't any need to "undersize" components before applying the coating. Does NP3 have any corresponding plusses over DLC, besides cost? View Quote |

The sharps dlc isn't quite as slick as iron cities, but it's still great! Also they don't coat the extractor. What kind of barrel are you using? You thinking about an echo trigger? Lol it's great fun! Not just fun though, it's a fantastic trigger for a duty gun. View Quote |

Binary triggers are cool and all, but the way the SLT seals all the moving parts up in the housing lends itself better to reliability. Being able to activate the safety anytime is nice too, if a bit niche. It's also absurdly light at just over an ounce, which obviously isn't the end-all be-all in a duty gun but it's a nice touch.

It's a tough call, but I think I'm going to end up going for the V7 2055 receiver set over the Master of Arms Esoteric. It's slightly heavier, and doesn't have a threaded bolt catch pin or takedown detent holes, but it has mag release fencing, a bigger trigger guard and short-throw selector markings. I've got the option to install a dust cover too, if I'm so inclined.

bah, we don't need no stinkin' port doors!
PWD update: all U data added. Also, a user requested a weight/length ratio in the FF rail sheet, so I added a column for that. It's ounces per inch. No surprise, the 15" brigand arms offering wins that particular race. Just 0.33oz/inch! I'm honestly not sure how many people will find that kind of trivia useful, but it was super easy to add so I figured "why not?". Same thing could be added for barrels, I guess...but would anyone be interested in that? All people really care about is the weight of a part, no? |

Is the vorn usa upper that weighs 7.1 oz in the PWD the same as the one that's on their website that says it weighs 5.7 oz? I was thinking of buying one for a different build that I am doing but not if it weighs 7.1 oz.

Anyone have experience with polymer dust covers from Mako or Kaiser US? I notice that Kaiser has a disclaimer on the description of their covers, which claims it's "X-7 Compatible Only," not quite sure what to make of that. It's just a dust cover, right? What kind of voodoo is going on that keeps it from being used in other upper receivers?

It's one of the best receivers i have ever used. View Quote |

It's hard to imagine that HERA has a worse rep than Mako. I bought one product from those clowns (rail system for my CETME) and the item I received looked like it had been bounced down 8 flights of concrete stairs. Totally unacceptable. Took months to get it replaced, and when the second one came in it looked like it had bounced down just 1 fight if stairs, so I said screw it and lived with it. I'll never order from them again.
As far as port doors go, everyone has to have their niche of expertise in this world, and I know where pscots is. |

Man, the word cetme has no place on the lightweight forum ?????? I had a ptr-91, stupid thing was like an anchor. And upgrade parts were so pricey... Gimme an ar any day of the week! I do like makos recoil reducing butt stock, I have it on my duty 308 riding a tapco 7075 commercial buffer tube. The tapco tubes actually have detent locks! View Quote |

Bah, adjustability costs weight. Over rated in a world with custom length CF anyway, right? If I share my ultralight, the borrower can deal with it.
BTW, i got my LuthAR charging handle. When I first got it the latch was refusing to open easily, like there was some flashing on a surface somewhere in there that kept catching on something. I was like "wtf?!", but after pushing the latch in/out for about an hour it's calmed down a bit. The spring they use is probably 3x as strong as it needs to be, which doesn't help ease of use for an already not so great design. All in all, not impressed. |

Catch me Hah!!!
I have my aluminum bolt catches coming (2). My lightest Tegra lower complete but without the CF stock and Taccom buffers and spring now weighs 172 grams or 6.05 ounces. Hoping I can get below 5.9 ounces before the Incognito CF stock gets here. Even cutting the bolt catch roll pin shorter will remove weight some. Since I am now in cardiac rehab (kicking my ass) and it's only 113 degrees outside, all I can do is work inside at my desk trimming weight off my lower receiver. I have to get all my safety gear out (HEPA Vacuum cleaner, dust mask etc) for cutting the CF hand guard back from 10.5" to 9 inches. |

I want, I need a Hesse upper! With that upper receiver I could try for 2.5 pounds.
My Luthar charging handle has worked great, might be because it sits in a polymer upper. Got an email, my aluminum bolt catches shipped. Does anyone know the weight of a steel barrel extension??????? |

There is no data base for the 308/6.5/7-08 ARs.
My ultra light polymer 556 isn't something I would use if the Zombies come out after the Jackasses loose the next election. The POF roller cam pin was lighter than any other 308 cam pin, even lighter than the V7 improved cam pin. Which they actually put the wrong weight on their web site! Also the 2A hollow titanium takedown pins are lighter than the aluminum 308 pins. But my AR308 is a perfect rifle, weight of rifle is 4.39 pounds with the polymer trigger group and 4.50 pounds with the Hyprfire EDT trigger. The 2A receiver set is a work of art, near perfection. I could try a titanium bolt catch, some of you will be dumping your expensive ones for the aluminum ones? |

The pamax tactical aluminum bolt catch is 5 grams :D i ordered 2 and they only sent 1... :( Maybe this is a sign from God that I don't need one on my 308?

My enhanced V7 tool steel bolt catch @ 7.970 grams or 0.2805 ounces by drilling a hole through the paddle.
So almost 3 grams savings with the aluminum bolt catch. How much did that over priced titanium bolt catch weigh? |
