AR-10 Slick-Side Uppers?

[FALex]

Well, I am contemplating picking up an AR-10. I have a couple 15's, and I enjoy them, so I figured why not get a 10 for the collection? As I continue to look into them, I am finding a vast majority of AR-10's have slick-side uppers (no dust cover, forward assist). I know there are some 15's that do not have these accessories equipped on them, but they don't appear to be as prevalent.

Since this will probably be my only 10, I wanted to build it up myself. I also wanted to use billet aluminum for the receivers. I looked into Black Rain Ordnance and Mega Machine, but they appear to only offer these slick-sided uppers.

All of that information for two questions:
1) Why are there so many 10's that are slick-sided? (A buddy of mine suggested it was because it makes the 10's seem more "sporting/for hunting" and not so evil and black...)

2) Out of those companies offering billet receivers, does anyone know of one that offers an upper with the dust cover and forward assist?

Thanks for the help and info all.

1a) because the forward assist and dust cover are fairly unnecessary.
1b) because the AR10 style or large frame doesn't have an industry standard designed off of one military platform. (like the AR15)

2) POF is a good one

Armalite is now introducing an AR10 that is compatible with the SR25 mags and has both the dust cover and forward assist. You'd have to contact them to see if they're selling the just the upper and lower receivers yet. Dust covers are great for keeping debris out of the action until you're ready to fire. Forward assist is debated constantly on here. If there's an issue with either debris in your chamber or defective ammo, you don't want to force it in with the forward assist. If your action has become sluggish due to foreign matter in the action, then the F/A may save your hide if things are about to get very deadly if you don't get a round chambered fast.

The mega only lacks the forward assist it has a dust cover and I am sure you would be happy with yours you can see the dust cover on the one in my signature.

I may be wrong but one thing I have heard is that they dont tend to have forward assists on the AR-10 type rifles as often because the heavier buffer spring tends to have less issue pushing it into battery.

Re: AR-10 Slick-Side Uppers?

If you "need" a forward assist on an AR-10/LR-308 platform rifle, you need to just yank the CH back and extract the round because it wasn't meant to chamber!!

Seriously, if the additional buffer spring tension and longer charge length of the big-bore ARs isn't enough to run a round home, or alternatively you can't manually push the carrier forward using the notch/indent on the carrier itself, chances are the round shouldn't be run at all.

There are multiple big bore AR-platform rifles in service without the F/A, including many that have served successfully in operations throughout the world. There simply isn't a need for them in any "real-world" setting.

If you want a big bore AR-10 type rifle WITH those features, the newer Armalite AR-10 rifles have them (as well as having compatibility with Armalite pattern mags or SR-25/DPMS mags...pick your poison), or POF (SR-25/DPMS platform) just to name a few.



ETA: just a clarification on the newer Armalites...you can get the newest models set up for EITHER the Armalite pattern OR the DPMS/KAC pattern mags, but NOT both. You have to chose which platform you want to run as they are NOT interchangeable.

I have thousands of 308 rounds through a couple barrels in my AR10 and I never needed the forward assist and the deflector hasn't deflected anything yet either, no need to worry about those little things.
cheers.

Re: AR-10 Slick-Side Uppers?

Some people believe that to use the forward assist to jam a defective cartridge into the chamber of a 308 rifle will only serve to truly jam things up. Once you really jam that cartridge into the chamber, your rifle may need complete disassembly to fix it, when simply extracting the defective stuck round may allow you to resume shooting.

If your rifle jams because it is that dirty, then the above logic still applies. You need to FIX the problem, not pound it further into the barrel.

Black Rain Ordnance AR10 receivers have dust covers.

I was just looking at a BRO upper/lower set. Man, all of those billet aluminum receivers look damn good! Mega, BRO, LMT, POF, etc...I can't wait to hit that Powerball on Saturday. I've got it in the bag.

Re: AR-10 Slick-Side Uppers?

I think you will find the BRO stuff to all be of exceptional quality and tolerance. I have more than one small & large frame guns. I prefer the receivers that are finished in "Nor Guard". That finish is exceptionally durable & low friction.

*Nor Guard is often referred to as "electroless nickel". It is a nickel boron "exoskeleton", if you will.

I am not sure this is strictly true. On my LR-308 if I manually push a case into the chamber then gently close the bolt, the bolt will stick behind the case and fail to close. The reason is that the extractor claw as not yet engaged the case. As a result, no amount of pushing on the bolt indent will push the bolt home. This is a clean and lubed gun.

At what point should the extractor engage the case, and how much force should it take to make this occur? Should you be able to make the extractor engage the case as I have described? Thank you.

Re: AR-10 Slick-Side Uppers?

I have both uppers,

i like the dust cover - wish the slick-side had it

never use the forward assist - if dropping the bolt on the round dosn't seat it, forward assist isn't

slick-side isn't as sexy

Re: AR-10 Slick-Side Uppers?

my POF308 has a forward assist, with around 2,000 through the gun, I have sot it completely filthy and never had to use the assist. My Armalite AR-10T has a match chamber, no forward assist, and still have never needed it. On the big boy AR's I think its more for show then go. I cant even remember someone telling me they used it on a 308...
