Get to know your AR-15 rifle - Upper parts. An upper receiver group consists of the following elements: upper receiver, barrel, gas tube, gas block, bolt carrier group, charging handle, forward assist, muzzle devices, and handguard. So if you are a gun enthusiast and you don't want to use stock solutions you are in the right place. Hard Charger is legit. I recently purchased two the hard charger side charger sets for my duty patrol rifle. They are robust and legitimately work without any problems at all. The system makes operating the rifle much easier and allows for a more positive grasp of the charging handle. It also much easier to operate the rifle from my support.

The main processes in printing a book involved setting the type, (the compositor in the background), printing (including proof-reading) and binding.

The next step: selling the book
Most books were sold by the printers or the stationers who commissioned the printing of a book. In London, the great centre of the book trade was the yard of Saint Paul's Church. Stationers also travelled around the country, selling their books at the major country fairs. Occasionally they would travel as far afield as the great book fair at Frankfurt (still held annually).
Often, to save the cost of binding, books were sold simply as sheets stitched together--probably such sheets are stored in the bins at the left in the illustration.

The compositor
The compositor sat in front of two cases, one, the upper, with capital letters, and the other with what we still call 'lower-case' letters (and ligatures--letters that were cast as a pair, like 'Æ' in this computer font). He would slot the letters, upside down, into a composing stick that would hold a line of text. The finished line was added to others in a 'galley' until a page was finished. This block of type would then be placed on a table to go with the other pages.
Two, four, or more pages, depending on the size of the planned book, were set in a 'forme,' then printed on one side of a sheet of paper. A full sheet, however many pages, would then be printed. When a book was finished the type was broken up, resorted, and reused.
Printing
Printing was a fairly simple process: the type was locked firmly in the forme, and a sheet of paper (slightly moist, to hold the ink better) was fitted onto the tympan, which protected the edges of the paper from inking; the frisket, which took the weight of the press, was then lowered onto it.
The type was inked (the man on the left in the graphic holds the inking pads), the frisket was swung flat, onto the type, and the whole arrangement was slid under the platen--the upper metal part of the press--which was pressed firmly onto it with the help of the screw so that a good impression would be made on the paper.
The completed sheet of paper would be hung briefly to dry, then stacked either for the second side to be printed, or for binding.
Stop the presses!
The first sheet would be taken to the proof-reader, but usually the press would continue with the uncorrected type until the proofreader had finished--after all the pressmen would otherwise have to sit idle. The result was that some uncorrected sheets would find their way into the book being printed.
When the proof-reader had finished, the press was stopped, the corrections made, and the press run continued.
It was rare indeed for an author to be on hand to assist in proof-reading. Shakespeare may have proofed his long poems, but he certainly had no hand in printing or proof-reading his plays.
The finished product
Finally, the sheets of printed material were taken to the binder, where they were collated, folded, sewn, bound, and the edges trimmed so that the folded pages were cut. The book was then ready for the bookseller.

One of the goals I had hoped to achieve during the 2010 SHOT Show was to find a better solution for building side charging AR-15’s. I already have one from Young Manufacturing but to be perfectly honest, the Y/M product is more of an afterthought than something that was designed specifically for this purpose. While Y/M is taking standard components and modifying them to work as a side charging unit, LAR Grizzly has been busy designing a completely new series of side charging upper receivers from the ground up. As you can imagine, I was very pleased when I stumbled upon their display, this past January, and discovered the LAR Grizzly OPS-4 side charging upper receiver.
The OPS-4 line consists of right side, left side, and ambidextrous options as well as the standard flat top, high ride, and high ride light versions. These uppers are available both billet and forged. The two uppers that we are showcasing are flat tops in both the right side and ambidextrous configuration which we used for the build on our Precision Rifle Raffle. The high ride versions are basically the equivalent to adding a riser to the flat top.
The first thing I noticed about these uppers is that there is no place for a rear charging handle. Considering that there is also no need for one, eliminating it altogether just makes sense. Of course, you still need a groove in the upper to allow for the gas key to clear so you can install and remove your bolt carrier group (BCG). LAR Grizzly’s answer for this was to add a thread to the groove and install a plug to keep the BCG from falling out when the upper and lower are separated.
For these kind of side charging uppers, you need to install the charging handles in the BCG. Looking back at the Y/M system, they have taken a standard BCG and modified them for use with handles. This means there are teeth on the right side which were originally meant to work with a forward assist. Since the charging handle itself becomes the forward assist, these teeth are not necessary. Using a BCG without the teeth makes it more difficult for debris to get caught inside and therefore significantly decreases the chance of a malfunction.
There are a couple of things to keep in mind about the left side of these upper receivers. The ambi and left side models come with a modified bolt catch that must be used in place of the standard catch. The reason for this is pretty simple: If you have a charging handle on the left side, it will strike the thumb lever portion of the bolt catch. The right side version of this upper is milled out to allow the use of a standard bolt catch, however, there is not enough room to install devices such as Magpul’s B.A.D. Lever. If you’re one of the growing number of people who like these devices, you will be happy to know that Phase 5 Tactical offers two different monolithic extended bolt releases which should work great on the OPS-4. Their EBRv2-SC will work with both the left side and ambi units.
In my honest opinion, I think the OPS-4 is a far better system than any other reciprocating side charging upper on the market. I’d also like to point out that I paid $459.75 for the Y/M system while the LAR Grizzly OPS-4 can be had for $300.00 or $400.00 for their billet version.
