Pick anything, its all great.. I was kinda worried about doing this on my own for the first time.. I took my time and things came out great!

I initially did a polymer lower to learn with. This 80 percent arms jig and lower worked great. I would recommend this to anyone interested in building a lower. Remember to wear safety glasses, ear protection, use milling oil, and take small increments. You will make a mess so work where it does not matter and can clean up easily.

Products I bought were very good

I have had nothing but great things to say to my friends about 80% arms. My last order was missing the end mill that I ordered and one phone call resolved it without issue. The replacement showed up later that week and I was able to complete my latest build.

Excellent through and through. Although I do like the style of the standard AR-15 lower more.

My orders came in a timely manner. Jigs are great quality, durable materials, fitted and finished to work for just about any user regardless of experience level. Satisfied!

Product was great and also fast shipping

good product.

I am very satisfied with the gst-9 80 percent lower I,ordered.I was happy with supports updates when asked.Originally I ordered a ODG lower and bought all the things to complete a Odg lower but after waiting for atleast 7 months,customer service told me they had no stocking date for my requested item.But I then was informed that black was in stock and could be delivered much sooner,So with the 2nd amendment climate here in Washington, I figured I had better take the black,It came in less than 7 days.But The frame was perfect,,the only problem was when I ordered the frame it was to ship with a compact grip and a full size grip included in the sale when I ordered during the special sale in June or July 2020,But I only g.ot the compact grip not the full size .while not a deal breaker I t still leaves me less than overjoyed with the experience. And even though I still need a odg frame to match the parts I bought originally before I was offered the black frame.My problem is the missing full size grip I paired for and never received. That was my only problem other than the reports of possible infinite shipping dates because of a problem with manufacturing processes.I am not sure I will be purchasing another frame from this company,even though I love the gst-9 frame,I. At try another vendor.

Excellent quality parts and tooling. I’ve bought 3 GST-9’s. My first full kit took a year to deliver due to COVID-19. I thought I had been scammed. I held out hope, they split my order, and it was worth the wait! My other 2 shipped quickly and customer service has always been more than helpful! Thank you!

Simply stated, 80% arms are the best. The communication, service, quality, and information are top notch. I’ve used the universal gen-3 jig for multiple AR-15 lower builds and the product makes it so easy to complete. Any mistakes are mine and not the jig. They’ve designed it to be as idiot proof as possible. Each time I use the jig it gets easier and faster. The lowers I’ve done the last few times are perfect. I just needed to get some practical hands-on experience to work through the kinks. If using the jig for your first build, get a practice lower if you can. Otherwise go slow and check that all bolts and and screws are locked in after every pass! Final nugget, make sure when drilling the hole for the trigger pins and the safety selector are perfectly perpendicular both horizontally AND vertically! Next phase will be the GST-9. I’ve got all 3 lower color - Black, FDE, and Patriot Brown. Can’t wait to dive in!

as described, great price, arrived quickly

Been buying from 80% Arms now for several years. Great Products and service.

Good products at a fair price. Ships when they say it will. What more can you ask for.

All of the items I have ordered (AR 9's) have been, for lack of better description, perfect. Shipping was nearly same day for me, arrived in 5 days, highly recommended.

I am a lifetime customer with these guys/gals, love the service. The site is very easy to navigate. Also the selection of merchandise is other wordly. You will always get your ites on time and very discreet packaging. Like I said I love these guys/gals that work here.

"Easy Jig" is an appropriate name! It's clear that all of it's appointments are well thought out, no doubt by much trial & error. The instructions are clear and easy to follow. My 1st lower came out perfect! Never having milled anything before. I'd love to add a photo of the awesome kryptic typhoon ceramicoat finish I had it done in, but Imac's instructions aren't nearly as clear as 80% Arms!

Quality product will definitely 👍 recommend and looking forward to future purchases!

great product the shipping was fast with a wide variety of merchandise and the service is the best.

Incredible product, puts P80 to shame. If the funds were there, i’d definitely have more of these!
