Attainable AR-10/SR-25

[sqlbullet]

Palmetto State Armory is changing the game on 308 AR's.  The recently released their DPMS pattern AR lower for 308 at a groundbreaking $159.  They have a completed lower for $299.  And they now have a 16" 308 DPMS pattern upper for $599.  That means a complete gun can be had now for under 1K, including shipping and FFL fees.

I personally find this really exciting.  I have gotten into building AR's.  In have a PSA lower on the way, and have pre-ordered two glass filled nylon lowers from TN Arms.  My gunsafe is definitely getting AR heavy.

The effect of PSA's quality budget AR10/SR25 pattern gun should be to bring pricing down across the market on this type of rifle.

Also has me excited for some wildcat options.  Looking at maybe building one of my three in 45 raptor, and handloading subsonic cast bulllets.  Who cares if it is only going 1100 fps when it weighs in at 510 grains.

I may have to give that a good look and see!

I did not need to know that.. already have two regular ar to build. I have been wanting one in 7mm08 for a long time now, it may actually get built at that price.

Then definitely don't look at this:

Pre-order still availble at 40% off.

I dont do preorders, especially from a company i have never heard of. Also you could not give me another polymer ar lower, see more than one crack/split in front of me.

Exactly what I was thinking as I saw they were reinforced with the brass inserts...I just take a sideline till my funds get to where they need to be.

I will let you guys know how it goes.

I personally think it is just a matter of time.  Glock was not the first polymer handgun on the market, just the first one to get it right.  TN Arms and the owner, Dave Roberts, is being very transparent about the whole process of developing their lower.  They hold the patent on the idea of the metal inserts.  And they have stood behind their products 100% with either refund or replace. Even, as far as I have read, the guys that bought one just to do destructive testing on it compared to forged aluminum lowers.

I got in on the early pre-order and got an even deeper discount.  I have two on the way for less than the price of one of the PSA lowers.  And when I placed that order PSA hadn't announced theirs yet.  At that time the cheapest I could find was about $200.

I really hope TN Arms turns out the the "glock" of poly AR lowers.  The company that gets it right.  I completely understand not wanting to be the one bleeding on the bleeding edge of the technology though.  That is what is so great about the PSA offering.

I want to build an F-Class/Palma .308 rifle, however, I would like to also have a Bolt Style upper as well for "Switch Barrel" options.

They are not the only ones using metal inside polymer for reinforcement, ati and at least one other do. The differences with glocks and other polymer guns is that they were designed from a clean sheet around the material. A polymer ar is nothing but a band aided design and never will be anything else. How much reinforecement do they add before it weighs more than an existing aluminum one? We are only talking a few ounces difference at best between the two at the start. Having seen what i have seen with polymer ar15s, you could not give me another one. The few ounces is worth the safety factor and extra rigidty.

Didn't say they were the only ones.  Said they have a patent pending (provisional patent) and once they are granted a utility patent they will be enforcing it.

Opinion noted.  Doesn't change the fact that I have bet on TN Arms product with my money, am still happy about the possibilities. and am therefore hoping they achieve success.

I am really thinking hard about getting one of the TN Arms polymer AR15 lowers to build a 10mm carbine with.

I am considering having the barrel cut to 14inch and have a 3 inch flash suppressor welded to the end of it to keep it out of SBR territory.

I also considered ordering their 3 pack deal, and have one of the lowers registered as a pistol, and build it with a 10" barrel.

Btw, POF is now building their ReVolt model in 5.56 and 7.62, which is their "semi-bolt action" model.

So I may just have to swing by and see them about building a Palma Grade upper for F-Class competition.

Why would you buy a polymer lower when PSA sells their SR25 style lower for $79.99?

[Pinsnscrews]

Weight. The idea being to build as light as absolutely possible. The polymer lower will be plenty strong enough for the 10mm.

Only do a 10mm polymer if you are buying a gas impingement upper. A blowback one will blow the lower. The ones i referenced in my earlier posts were both .40  blowbacks and failed rather spectacularly after a few hundred rounds. One of those owners killed two lowers from different manufacturers with the same upper  before finally listening to me and switching to an aluminum lower. He has had zero problems since, over 2000 rounds later.

Do you have a link for that price.  The PA-10 is 129.99 on PSA's site right now.  The PTAC lowers may have been cheaper, but PTAC.
