One piece polymer lowers

[Texas by God]

My local LGS has a box full of these for $30 each. They take special takedown pins and A2 buttplates which are not included.
They use a carbine length buffer & the stock is the buffer tube. They are great for a lightweight AR build. PM me for contact info if interested. They are Sabre Defence brand.https://uploads.tapatalk-cdn.com/20180208/58cda9dd2cb418fd0e65c819d36f92e6.jpg

polymer/plastic lowers have a very bad reputation for breaking off between the grip and the buffer tube.

polymer/plastic lowers have a very bad reputation for breaking off between the grip and the buffer tube.That's why these are of one piece construction. They don't break. Google Cav15 and watch the torture tests. I would not use the conventional type you are talking about. GWACS in Oklahoma is the maker. I'm very impressed by mine and a cool benefit is the snug fit to the upper. None of that play that you have to fix.
Do yourself a favor and try one; it's the same as a polymer frame handgun. I have other ARs but I hunt with the Light one!

Got rid of my A2 stocks, eliminated more weight. Filled poly is very strong, but I'd like to see metal reinforced to prevent warping. Also forces a rifle config.

I like the trunk for storage and no rattle like a telescoping stock has. To each his own.

My .300 Blackout here has a 4x Nikon, sling, and 30 rounds of 110gr reloads aboard. https://uploads.tapatalk-cdn.com/20180209/6bd4d7ea5d1592beac13f37aacf343bf.jpg

I like that!

Looks like a nice idea for those of us that like the A2 stock .

A good deal! I looked around and found the manufacture and there price was 129 or 80 for a blemished one and then add shipping and FFL transfer. At $30 ea plus say $20 ship and $20 FFL fee that's not bad, I believe my local GS will transfer up 3 guns on one fee as long as it's from the same place and all done at the same time.

They had about 12 left last Friday. Now's your shot.

A 5.56 in black. These are very handy carbines. A great base for a PC carbine as well.https://uploads.tapatalk-cdn.com/20180221/7d6c9f3d0247cf232f5cce11c44e5103.jpg

Those look like the old Cavalry Arms lowers. They had a good rep back in the day, before the BATF shut them down. Seems like they cast the two halves of the lower in-house, then sent them out to have the halves welded together. BATF found out, and made them stop production. They said that Cav Arms was not 'manufacturing' the lower, and that whoever did the welding was. The welder was not appropriately licensed and had no interest in becoming so. Cav Arms continued making AR furniture for a while, and may even still be in business, for all I know.

ETA: Yup, they are. http://www.cavmfg.com/Firearms-Accessories-and-Components_c11.htm

GWACS is the current manufacturer as far as I know. I got the takedown pins from them. These are marked Sabre Defense and came from a police auction I'm told. My .300 is assembled on one marked CalvaryArms. My experience with it made me get these when I stumbled over them.

One thing negative about those one piece stock Thomas :kidding:is you can't put a bump stock on them!!!!

To continue this- I've decided on another .300 Blkout because I got a great deal on a barrel. Coming soon to these pages.

If you own a .300 BO and a .223 AR, devise a means of POSITIVELY IDENTIFYING your .300 BO mags. It does really strange things to the bullet/boolit when you fire a .308 down a .224 bore. I've seen too many incidents of that to ignore the problem. Somebody gets in a hurry and grabs the wrong loaded mag. The cartridge will chamber and the bolt will lock. The rifle will fire, too! Bad news, all told.

Absolute advice! Personally I paint & sharpie mark my .300 mags and leave my 5.56 mags as is.
When the first .300 BO arrived at our deer camp, I showed everyone present that a .300 would indeed chamber in the 5.56. I removed the firing pin first. The OS look was on everyone's face!
It can't be said enough.

I watched a video of the aftermath of firing a 300 blk in a 223 rifle. The bullet was still in the barrel and was swaged down into a long skinny copper spike. The upper blew apart and the bolt carrier was peeled like a banana. I’m a lefty, so I especially worry about the FA know being blown into my face. Can’t be too careful.

On topic: I built a lightweight rifle with a 16” pencil barrel on one of the GWACS lowers. It is a fantastic gun, and I am absolutely convinced it’s just as or maybe even more durable as a conventional aluminum lower. Molding the stock and receiver in one unit eliminated all the issues with using polymer.

Since these came out I have used them to build 9mm,223,6.8mm carbines and have never had a problem with one.People have issues with them because they are not tati-cool looking.

Any more of these lowers available? Anyone have one they dont want? Very interested if so.

[Harter66]

On the mags .
I had a 6.8 and a 556 . Getting them mixed up isn't a big deal . The 6.8 in 556 won't battery and the 556 in 6.8 just reforms the brass . So the 6.8 got ASC and AR Stoner black SS mags and the 556 got plastic ...... don't know why I can't remember the name now .

Anyway the first AR was an ATI Omni Hybred with aluminum re-enforcement from the grip screw boss to the buffer tube boss . 2000+ rounds no problems . I imagine if you used it like a club it might be a problem and would most likely break across the FCG or mag well . The AL fittings are thin and probably investment cast or stamped straps form rivited the the bosses . I don't make it a habit to beat on guns but I was not unhappy with the poly metal gun . It did what it was supposed to do when it was supposed to do it . I think the poly receivers have come a long way from the super purple monster (purple poly whatever) $19 plastic wonders of 1997 . ATI has a full day in the desert do 97 things bad to your AR including several drops from cars and an altitude drop 50 or 100 ft , I can't remember now , sand ,mud , heat etc and firing like 1000 rounds during the abuse cycles .
Sure it's a sales pitch and there's no way short of doing it all yourself to proof it but it's there .

You know everyone thought old Bill Ruger was nuts for going to investment cast parts too .

Here's the .300 Blackout I "assembled" on the lower. I got some good deals along the way, $360 as it sits. I may put a dust cover on it but probably not. I hope it shoots as well as my other one.(or better)!https://uploads.tapatalk-cdn.com/20180613/efb961979cff3f4568c970bca84b0f5f.jpghttps://uploads.tapatalk-cdn.com/20180613/7466aca9e70b8d5877649fc2d6b4ed4e.jpg

Completed with a tough old steel Weaver K4. It's still in the High 90's at dusk so I haven't felt like shooting much. I may have to do some pre dawn shooting this weekend. Wake up, neighbors!https://uploads.tapatalk-cdn.com/20180702/8cd70966802db500c137448ee01a7b4d.jpg

I wanted to try one (or two) of them but I couldn't find an FFL to receive them as per the stupid NY safe act it would possibly considered an "assault weapon". Dumb laws, if it has a removable mag it can't have a pistol grip.

I have a Cavalry Arms lower like this. Several thousand rounds and no problems. I also have a carbon fiber lower (no stock attached) by Plum Crazy with several thousand rounds through it. No problems.

Since the first ones came out I have had 8 that came and went in all calibers only issue I ever had was the seem on one came apart at the rear of the stock on a 9mm. This was caused by a too light buffer and hottt loads little gorilla glue fixed issue and its still going. I have just built a 9mm on a tennesse arms polymer lower 1500 rds so far and no issues.

[Texas by God]

I feel that a mention should be made of the selector switch installation on these lowers. It is a blind hole for the detent; once it is in there, it might not ever come out.
So make sure you get the trigger in that you want BEFORE installing the selector.

I have seen some crazy stuff with brass I buy. Love seeing when people fire a 9mm in a 40sw, or 40sw in a 45acp. As far as the 300bo out of a 223...thats a bad bad day for sure.

[trentvb]

These look cool.

[Texas by God]

I've built my last one. I had to fit it a bit but there is ZERO play betwixt the upper and lower. This one is 7.62x39 with a bullet proof Weaver K4.https://uploads.tapatalk-cdn.com/20190521/acb31cffbcbcaef09f7962b4fb2cb2f8.jpg

Texas By God not to steer the thread but you got me curious as to what my 10.5" 300BO weighed after it is all finished. Magpul Gen II sights, Magpul sling, 30rds of 220gr subsonic, 7lbs 14.4oz pretty pleased with the end result.

That one looks very handy, Doug Guy. I haven’t weighed this one yet. It won’t be as light as my BO due to the steel scope and the ff forend. Are you shooting cast in that pistol?

No sir, that is my last piece of storm prep, assemble, proof it, sight it, load it and park it in the ready spot where it will sit and hopefully never be called to duty.. It's for looters, thugs and drive bys which seem to permeate the landscape in the wake of a disaster.

Whatever is heavy weight and subsonic at wallyworld is what fills the mags.

Gotcha. I live on the farm so mine is stoked with whatever jacketed supersonic I have loaded. It’s set up for grab and go as well. If this one shoots cheap ammo well, I will only reload hunting ammo when needed.....
