Crafting a rifle from a bin of parts is an enjoyable past time that I recommend because it is not difficult, but it does require some moderate effort and mindfulness on the part of the craftsman.
Everything has a set of tolerance ranges that is important to abide when constructing but ultimately, for not a lot of technical difficulty, a bespoke rifle can be crafted to your exact desires.
“What’s in a name?”
I suppose it is appropriate for one to consider manufacturer’s efforts and purchase a fully-built, turnkey, rack grade rifle but whatever I call mine I’d be lying if I wasn’t a bit prideful in the end result and for that reason, I build — and because I can.
My rifle fucks, and is a reflection of the man who built it. I wish that for yours too, because what does it say of a man whose rifle is impotent and broken?
In life, some things are inexpensive, some things are cheap, and some things are worth more than they command. An inexperienced eye cannot tell the difference betwixt the three and so defers to present and individual value.
I’ll save you the trouble and say that good cartridge brass lasts and is worth it to pay some small premium for reliability. Simply, upon detonation, it obturates, seals and is ejected in fractions of a second should everything operate as it should and sometimes…it doesn’t do any of that.
A rimless cartridge can shear at its rim, and let me warn that should you not have a plan nor a prayer in that moment, you are simply dead in the water.
It’s easy enough to remedy, if you know what you are doing, but slender cylindrical rods are not often found by happenstance in nature and if it’s dark and you need a second shot, it’s not going to happen.
Buy good brass. A lot of it. Because the sun is setting and one might not shoot enough to understand the necessity, but it is wise to acknowledge the present and individual value of appearing prepared.
Don't get me wrong, the PTR-91/G3 is cool, but it's a night and day difference. The PTR 91 damages the brass pretty bad upon ejection (a problem for people who like to reload), and has a problem with the OEM hammer breaking. My bro's hammer on his PTR 91 broke after just 3 or 4 mags worth of shooting from brand new. Also, the PTR-91 recoil is a motherfucker. It beats you AND the brass up. In comparison, a good AR-10 kicks not much more than an AR-15 and is smooth as fuck. Plus an AR-10 has a lot more aftermarket parts.
Fireforming 7.62x39 to 6.5 Grendel is the limited hangout of the reloading world, but having already been necked down, the only thing left is to pop smoke
