Description
308 80% LOWER RECEIVER AND JIG SYSTEM – FLAT DARK EARTH
After two years of planning, design, engineering, and testing, we’re proud to introduce the industry’s first reinforced polymer receiver designed for the DPMS styled .308 in an 80% format. 308 80 lower receiver and jig system.
Our AR-10 jigs are designed with first-time builders in mind, so we have built-in safeguards to prevent common errors, drill bit depth guides, a manual, and tutorial videos to make the process even easier! With instructions and basic tools in hand, you can confidently complete your AR-10s lower in around one to two hours.
.308 80% Lower Receiver & Jig
Our .308 80% jigs provide you with the tools you need to complete that AR-10 clone or 700-yard bench rifle receiver. Choose the rugged Elite Builder Jig, fabricated from hardened steel with drill bushings, and confidently cut and drill your receiver for your lower parts kit, upper, and buffer system in a single afternoon.
Jig & Receiver Compatibility
These jigs last for long! One metal AR-10 jig can easily complete twenty or lowers without having to replace any plates from wear-and-tear. Want to spend as little as possible on your 80 percent lower .308 build? The polymer jig-and-lower combo kits come with both an AR-10 polymer receiver blank, the jig, and the bits!
Also, each of our stand-alone .308 jigs is made compatible with the popular DPMS LR-308 (gen 1)-type .308 80% lower receiver. These full-size receivers closely mimic the size and shape of the original ArmaLite-10 platform. Therefore, offers you the opportunity to build an accurate 7.62 NATO or .308 shooter from the ground up.
The .308 80% Lower Receiver Design features:
- Unique reinforced polymer design with solid core design
- ATF compliant design
- Beefed up buffer tube ring and ribbing across the entire upper surface area.
- No-thread design on the pistol grip area.
- Stiffened magwell, ultra-light design.
- See the product page for additional parts list
Is it legal?
YES! The 308 unit is well within the defined parameters of a “receiver blank” defined by the ATF. Therefore, it has not yet reached a stage of manufacture that meets the definition of firearm frame or receiver found in the Gun Control Act of 1968 (GCA).
AR-308 Jig: What Comes With It?
The Polymer80 .308 jig includes all parts required for machining, including the polymer receiver blank itself! Purchasing a stand-alone jig like the Elite Builder also provides you with all components necessary to cut and drill your receiver blank:
- (2) Side plates
- (3) Top plate templates
- (1) Set of HSS drill bits
- (1) HSS end mill bit (center-cut)
Tools Required:
- Drill press
- Table-top vise
- Cutting fluid
Other 308 80% LOWER RECEIVER AND JIG SYSTEM color kits available:
While other jigs on the market require a router or milling machine, the Elite Builder’s HSS end mill bit is designed to allow you to cut the fire control cavity with plunge cuts, vertical cuts made with the end mill in a similar fashion as drilling the cavity’s pilot holes.
This is easily accomplished using a cross-slide vise that affords lateral movement.
In conclusion, with a cross-slide and press, you can complete your 308 80% LOWER RECEIVER AND JIG SYSTEM – FLAT DARK EARTH blank within two hours.

Have always had great success buying and selling on polymer80framekits.
Igor Malyshev –
Excellent web site with plenty of helpful information and intuitive navigation. Thank you!
Frank –
By far the best sight for buying and selling gun related items. The down side is that they have increased their fees, and made major changes to the formats.
Prairiedog –
The exact same address to which I have received shipments since 1986 has somehow become insufficient for some vendors. Otherwise I would have given 5 stars.
Peter Zimmerman –
Greatly improved service. Wish the search engine was better though.
chris juhl –
Perfecto
I have purchased three weapons, one I made a mistake on and had to cancel, and every dealer has been exceptional. Very good choice when looking to purchase a new or used firearm.

I had looked all over and went to a couple of gun shows to try and find a specific firearm with no luck, I watched on gunbroker and within a short time I was able to find the firearm I was looking for. I was able to make the purchase with ease and at a better price than I was seeing elsewhere. I look foward to making purchases in the future. Thanks Christopher!!
J. Cruser –
Never had a problem with GunBroker. Probably the best site to find good gun deals. I’ve bought several firearms from this site. Def my go too.
Jeff –
I’ve been using GunBroker for approximately 10 years. Never had any issues. Keep up the good work. Thank you.
Joseph Svoboda –
Every transaction goes flawlessly time and time again. An excellent business model
Louis Polsinelli –
I liked it better in the old days when I would email the buyer and conclude the auction.
I think the new website that tries to everything for the seller is confusing and difficult
Kal Nelsen –
Placed my order on a Thursday night, and received my pistol after 3 business days!!!!! The price was $60 less than I could find locally, and the shipping was FREE!!!! Great job guys and gals!!!!
Casey Parker –

Being new to the world of firearms, I was a bit nervous about assembling a lower receiver on my own. However, the 308 80% lower receiver and jig system made the process incredibly simple and straightforward, thanks to the customer service rendered.
Sydney Smith –
This is best site for any gun enthusiast. Can judge the value of firearms by comparing listings, buy whatever you can afford, and some you can’t. Love this site.

I ordered several times from P80. They are fast (next day delivery), they have a lot of choice and their prices are really fair. Once I asked a question and their answer was useful and fast.
I recommend them.
Felix-too –
need to state ALL information regarding antique firearms & the restrictions to the various states for shipping
Joe Matt –
I was a little hesitant ordering overseas but after reading the positive reviews I decided to give P80GB a chance and I’m glad I did. The shipping was super fast (I’m in the US and I received my order in 3 days!) and customer service was awesome. They answered my questions quickly and professionally and I’ll definitely order from them again.
Howard Delo –
I’ve always had a great experience using polymer80framekits!
Benny Scarcia –
price was right, availability was in stock and reviews were good. Well, P80GB did a great job getting my order to my door in a short amount of time. Boxed securely inside a plain box and I must say, I’m a happy customer.
John Traven –
The website was easy to navigate & locate what I wanted. Considering all the delivery 🚚 issues going on these days my order was processed & I received it very fast.
Mobby Dark –
I recently purchased the 308 80% lower receiver and jig system in flat dark earth and was blown away by the quality of the product. The finish was impeccable and the jig system made the assembly process a breeze. I highly recommend this product to anyone looking for a reliable and easy-to-use lower receiver
Felan Reeves –
Price was right, in stock, shipping fast and website fast and secure.
Gerald Busemane –
I’ve been using the 308 80% lower receiver and jig system for a few months now and have had nothing but positive experiences. The precision of the system is top-notch and I was able to complete the assembly of my firearm with ease. The flat dark earth color also gives it a sleek and stylish look. Highly recommend
Manuel Lopez –
Excellent service fast shipping and reasonable price,product arrived as described and on time I will not hesitate to order from them in the future
Hdrk1111 –
Great transaction, great seller, polymer80framekits attracts some really decent folks.
Jerry Carter –
I have used polymer80framekits for the past 3 years as a small time collector of handguns and a few rifles. I have always been very happy with their customer service the few times I have needed it. The best online gun sales website. I don’t use your online checkout. I do use a gun shop in my home town as my FFL dealer to receive and ship ALL guns I sell on your website. They ALWAYS get a signed and current copy of the buyer’s FFL (usually their gun shop’s FFL). They now ship all handguns via USPS Priority Mail with full insurance.
Patrick Campagnard –
Good selection of goods at reasonable prices. Also they ship the goods very fast. I would recommend polymer80framekits.com to my friends.
John –
I ordered from Ireland and my package much sooner than expected. Everything was packed safely and neatly. They seem to care about their customers. 10/10
Morten –
Always fast shipping and great service, got a gun that is not working, but they were were helpful in troubleshooting and ultimately return.
Tibo –
Nice packing, good website and very friendly people. A lot of things that are not in stock just dissapear from the website tho, so u cant place a reminder when it gets pack 5such, as batteries, magazines etc.) would be really nice if this gets an update or sms. D_For the rest, great customer support.
Georgi –
Great shop with a variety of items to choose from! One thing to fix is that some items only come with a description in polish (most probably a site issue).
Alan –
I got a fantastic deal on a spec arms edge 2.0. Over 50% off. I couldn’t be happier
Oskar –
Best shop in Poland, there’s no doubt. I have never had any issues with customer support, guarantee and quality of their stuff. I totally recommend buying there.
Maksa –
The weapon meets expectations perfectly.
It can be used out of the box after the settings.
The shoulder support keeps you stable.
Marco –
Everything came quick, even tho i’ve ordered a wrong item, the support on the phone quickly changed everything to the way i needed. Support was friendly and speaks fluent english, which is a big + to a foreign customer.
George –
I ordered on polymer80framekits.com I received the order confirmation immediately. 8 days later I received the order, very well packed, in exceptional condition. They are very professional, you can find almost anything on the site. I recommend them with confidence!
Argiris –
I’m only giving one star because you informed me that my package would arrive in eight days and it’s been fourteen and I still haven’t received it!!
Jonáš –
Great shop with alot of different parts and wares for a good price. Easy to deal with, shipping is a smooth process and they’ve helped me with answering questions I’ve had before.
Philip Marks –
What an experience. First time using the company looking for an imitation firearm for airsoft, found the item and ordered it at a very respectable price including delivery. Whilst going through the process, I was kept in touch with by a couple of advisors who guided me through a downgrade required for Customs clearance and processed this as a priority without even a request from myself. I was happy with the response times and the way I was treated. If you do one thing in life….use these guys!
S. Doyle –
Overall
The packaging time was quick, the deals are great, everything was packaged neatly, so no damage during shipping.
Everything was in the package that i ordered, nothing faulty out of the box (i havent played a game with them yet, but as far as i can see, no issues during fitting and test fires on the range).
Payment was easy.
The only downside was UPS, and their delivery drivers, (they said they were at my door, but my CCTV footage says otherwise) so i guess because the website choose them as one of their delivery companies, that is -1 point.
Overall score 99/100 would recommend.
J.A. –
It was a great deal. Using the Site is easy, the process of shipping was very fast (3 working days inside EU!).
Sr. SANTOS –
The only reason that i’m given 4 stars its because the client support. I had ask a question about an item, but didnt get a reponse.
J.A.Spiridon –
Greetings ! first time i bought from your place,recomended by another airsoft enthousiast from my team. Happy i was not cheated on and got what i bought with no fuss or waiting extremely long times to have my items. All questions i had were answered within one day of asking them. Everything works as intended. One thing that had me frowning is that the package was opened when i got it and taped up again. maybe a random check? i dont know. either way, i am very happy about my purchase !
Tiago Alexandre Arsénio –
I purchased a tone of equipment and the customer service was just INCREDIBLE.
Brumes –
A few days after I made an order it seems like my ip was blocked again, I cannot acces the site without using a VPN anymore. This is incredibly embarrassing
Barnabas –
I have ordered several products, but I am satisfied with the quality of all of them, as well as the prices. I would recommend the site to others, especially those who want to buy Specna Arms’ products at a relatively low price.
Iancu –
Great Customer Support, great delivery. Thank you guys!!!
Vasil Valkov –
My item was out of stock, after a few days it got back in stock, and i was able to purchase. Great time using the shop, having many choices.
Majerik Dávid –
Best costumer support I have encoumteted. Helpfull, fast replies and they will always tell you if there is some kind of a problem with the product that you ordered. And can be trusted.
Aleksander –
The receiver overall is perfect, metal is with a good quality and feels strong. It also easily fits CORE and EDGE gearboxes, although the spring is blocked by the nut, so to change it you have to open up the receiver.
Deidre Davis –
Quick, helpful and very easy to deal with.
