ar-15 matched receiver

All the replies are really helpful. Getting a good ar lower manufacturers can be difficult sometimes.

Gee J that is too bad, you are underwhelmed.
As someone who has multiple copies of the Ar, I prefer the 6.8, underestimated as they at the 68 forums prove.

But for a battle rifle I think SScar 17 and LMT have eaten all the ammo types I have.

Now the LMT MWSF same caliber, different purposes unless you are used to carrying an M1 or M14.
Either way you cannot beat the weight of the SCAR 17 plus the extra ammo you could carry 2 mags maybe 3.

But what do I know I even have a sword for if and when primers run out.

Still value your opinion, but as the OLD ORIENTALS would say.


He who knows and knows he knows is a wise MAN, follow him.
The rest are either too dumb, asleep or ready to be taught.

I guess if we want to be technical we could say the AR-15 flatters the AR-.10.

I am talking the Ones, the Pork Chops carried.

For a great article Look for untold stories Men and Balls about the Portuguese. Now I know why my step dad got in at 39 and left after V-E day.

Be Well.

It's by Rainer Daehnhardt. Lives in Portugal and is of Prussian ascent, I think.

Enjoy, if it's your thing.

i am not too sure how to reply, because i really don't understand the tenor of your remarks very clearly.

it is difficult for me to understand whether you are talking rifles, or if you are talking calibers.

the fn scar, "heavy" or "light" is not a bad rifle. it is a fine rifle.

it is not, in my view, anything that represents any kind of a departure from the ar-15, or things that fn has been doing in its other battle rifles for many years.

as to the upper, with the exception of the gas system, it is basically derived from the ar-15.

as to the lower, it has the same control layout, and departs from the ar-15 lower most significantly in the trigger control group.

there are many after market triggers, by geissele and wilson, for instance, that would improve the ar-15 system, if it needed improvement at all.

in sum, i stand by the opinion that anything the fn scar can do, the ar-15 platform can do as well.

i see absolutely nothing wrong with the fn scar, and i see no wise in which it is superior to the ar-15 platform as developed.

as to the lewis machine & tool ar-15's and ar-10's, especially the rifle adopted by the brits for a squad marksmanship role, they are just hard to beat.

as to calibers.--

the 7.62x51mm nato is a wonderful tool. it is a good cartridge to 800 to 1000 yards, proven time and again.

it is also a bit overpowered in terms of energy and momentum as used against human targets. this, of course, is in the realm of military usage.

i happen to think that the british got it right in the early 1950's insofar as the development of the "intermediate infantry round" goes, when they developed the .30/280 british infantry round.

it was designed around the same parameters and thinking as the soviet 7.62x39mm (model 43), and has the twin virtues of being just as tractable and manageable to shoot, and in being significantly more powerful & more efficient ballistically than the russian.

i am developing a wildcat version of the .280 british, you can read about it here.

i have an upper in 6.8mm remington spc and consider it a fine cartridge, very accurate and very manageable. it would make a wonderful little squad machine gun round, say in a weapon along the lines of the russian rpd.

the 6.8mm remington is far superior, in my way of thinking to the 5.56x45mm nato, and is a step in front of the russian 7.62 (model 43).

i prefer it to the 6.5mm grendel, but i think the grendel a good cartridge as well.

i think the .280 british far and way superior to all those rounds. and, if you look to the facts of the matter, the .280 british does not give up very much to the .308 either, and is much more tractable to control than the .308. if you look to films of the trials involving the .280 british and the .308 (the t-65 cartridge at the time of the trials), you will see the .280 much easier to manage under full auto fire. (british pathe film service. google it.)

as to old chinese sayings.-- they have kept the fortune cookie guys in business for a long time, so i guess they must be pretty good.

p.s. yes, the ar-15 flatters the ar-10, which stoner and armalite developed first in time. they then downsized the ar-10 to handle what became the 5.56x45mm nato.

and, both rifles "flatter" the johnson semi automatic rifle, model of 1941 in conception, layout and function of the bolt and the like. this is no accident, because melvin johnson (inventor of the johnson rifle) worked with stoner at armalite.

you can look it up.

p.s.s. johnson also was very instrumental in the transformation of the gatlin gun into the vulcan cannon, and did early experiments attaching electric motors to gatling guns to increase the firing rate.

you can look that up, too.

apples to apples.--

the 7.62x51mm nato with the 150 grain bullet, about 2650 fps in the service loading.

(civilian loading, for bolt actions, is a bit higher.)

the .280 british, (or 7x43mm) was loaded to around 2500 fps with a 140 grain bullet.

(civilian loading, for bolt actions, can attain around 2600 fps according to various "authorities." i load my little "jj's brit" ™ to 2500 fps w/ 140 grain sierra flat base bullets, with no strain whatsoever.)

i would not want to be shot with either cartridge, and i cannot see that there would be a lot of difference in the experience. dead is dead.

just yesterday, i was shooting the 300 yard gong at the local range with jj's brit, a 120 grain nosler ballistic tip at about 2650 to 2700 fps at the muzzle.

a 10 or 11 year old boy shot the rifle once from shooting pads, and whacked the gong with no difficulty at all.

nor did he have any trouble managing the rifle.

i don't think the experience would have been as enjoyable for him shooting a .308 .
