Para-Shooter from United States, OR Public Profile

I used these on a PCC build. Skeletonized receivers, black with red pivot/takedown pins, charging handle, magazine catch/release and castle nut. It comes with a brass guide pin making the install a breeze, the screws come with a blue locktite like material on them

If your rate of fire is creating bolt bounce or even won't run, you MUST run a "dead blow" buffer. These are not the cheap one-piece steel buffers, those are junk, don't waste your time and money. Dead blows usually have three (or two) internal weights consisting of aluminum-steel-tungsten, the combination depends on the desired weight. H3's are usually all tungsten hence the price. In this case brass is used, and at 5.4oz should tame any bounce issues. If rate of fire is your thing, buy an adjustable weight kit, start at 4.7oz and gradually add weight until reliable cycling is reached. The added bonus of reduced recoil and not beating your firearm to death. Is this "the best" buffer available? No. Is it the best H3 buffer under $40 (on sale), most definitely!

That's right, I said it. Why? The Superlative Arms gas block has a patented system where it can either block OR bleed of gasses. How it works: The block ships in the closed position. Turn the allen key 4 1/2 turns counter clockwise and it is now fully open acting like a standard gas block. If you want to slow down (reduce gas pressure) you have two options. Turn clockwise and you begin blocking the gas port, just like any other gas block. However, you have 18 clicks of adjustments for fine tuning. OR, continue turning counter clockwise and the gas port remains fully open, but you now bleed off pressure through the port in the front of the block. This allows you to allow the gasses to escape the system rather than remain in the barrel. When shooting suppressed, it lessons the "pop" sound signature at the ejection port. Testing shows this is worth a couple of decibels, the more gas you let escape, the quieter your suppressed weapon will be. It's only a couple of decibels so you may or may not notice by ear, but sound carries by distance, your noise perimeter will shrink. Since you have less gas going through the can, it will run cooler and withstand sustained rates of fire longer. Your can will thank you.

If your 9mm pew pew isn't running correctly, this right here is a must have, the elusive 10oz buffer. At times tougher to find than a 10mm socket, the Kaw valley 10oz buffer is the go-to.

Yep, you read that right. Being an aging paraplegic with arthritis in the shoulders and one replaced, stretching out to support those 18-22 inch barrels isn't pleasant. I find 12 inch builds much more tolerable, and a 308 in this configuration is good for 600 yard shots (I'm just a target plinker. This one-stop kit was the perfect finishing touch with an SBA5 brace. A Nomad L can takes care of the bang and flash

While it may nit be the most fancy high end catch out there, it's definitely a steal for the price paid. AR10 LPK's are notoriously expensive compared to the AR15 counterpart, the difference being the bolt catch and the magazine release. This budget buy allows to to be a bolt catch away from building an AR10 LPK at AR15 pricing

Great barrels for the money, the 300BO barrel looks to be a rebranded Faxon, but don't quote me on that.

I compared this to the Faxon in the same configuration (I own other Faxon's as well) and I believe this to be a re-branded Faxon. Same material, profile, twist, finish, I.D. fonts...just different logos and a $60 price difference. I scoped the barrel while installing the gas block abd aside from a small burr at the gas port (easily removed with a brass cleaning brush) the bore looked fantastic.

These springs do just fine for the intended purpose. I highly recommend having a couple of spares on hand. If not, Murphys law will always strike.

I ordered two of these, one sniper grey and one burnt bronze. I started with the dust cover. I oiled up the hinge pin and fitment was unusually tight, so tight I had to use my tiny AR pin hammer to tap it in. Same thing with the forward assist, I was thinking the roll pin was just a tad large, it took some serious blows to drive it in. The WTF moment came when I went to slide it on my midwest upper receiver rod for barrel assembly. The farther on it went, effort increased to the point I was using a rubber mallet. I stopped maybe 2 inches short of where the barrel chamber engages as i was concerned about getting it off the rod.When i went to insert the barrel (ballistics advantage) it wouldn't even begin to go in. At this point i broke out the dremel and wire wheel to remove the cerakote in the whole, an there was plenty of it! I had to use the barrel nut to pull it into the fully seated position, its that tight! I've used this same upper sold by other companies, none were like this. When I tapped it off the receiver rod (3lb hammer and old nylon foregrip) it actually wore the anodizing off the rod in places. I've came to the conclusion that the cerakote was applied way to thick. I suspect that tomorrow i will be removing cerakote from both front and rear pin holes, and check the BCG fitment. Outside of the cerakote being about .002 too thick everywhere it's great. If ABC machined this, its on them, but I doubt that since it's every feature. We'll see how the Bronze one goes.
