Ones that are forged from 7075 aluminum alloy from a milspec contractor. 7075 is about twice as stong as 6061. Same thing with the reciever extension.

I would stay away from the KE Arms Jig. I bought one and it would not even fit their 80% lower. Also the top plates, they have oval holes to mount to the side plates. I assume it’s to accommodate different lowers, but now I will need to find a way to center and square it up. With a little work I’m sure I can make it work but was a little disappointed. The forged lower I got was great, I think it was out of Cerro forge.

I like "the blue jig". I don't have any experience with anyone else's jig, but it's been nicely compatible with all lowers I've played with so far, and the AR-10 jig was easily relieved for cross compatibility (since no one's 308 stuff is compatible with anyone else's 308 stuff)

Price was right and parts are replacable.

The only thing I DONT like about it is the drill holes have no hardened bushings.


My suggestion: If you DONT buy the blue jig (google that, you'll get it), get a jig that has hardened drill bushings.

you can disregard all this if you just want ONE or two lowers. For a bunch, I have my opinions.

for lowers, contact our own coltprswaydr. The prices are reasonable, the quality is excellent, and he may still be offering qty discounts (I dunno) for buying a bunch. He deserves our support. He's a vendor here, so by supporting him you are supporting the dollars he paid to calguns. So support him, you support calguns.

Oh, and at the time I was buying, even in a saturated market, had the best price on 308 lowers. Not a little bit better either, it was a lot. I dunno if everyone else caught up yet.

We do we have a jig with a lifetime warranty on the side plate. had drill bushings on on side with optional drill bushing on both side if you desire. it will cost you $125 free shipping for cal guns members. it also comes with a pdf file of the instructions. it works on pretty much all of the billets on the market and all of the forgings. it is taller than most jigs so you will not have to use a set of parallels to hold the jig when you are machining a billet with a enhanced trigger guard. it has screws that hold the two side plates together when drilling. the reason for this is most vice jaws are not tall enough to secure both top and bottom plates together when drilling
see the pics

as for lowers anodized are going to be $120 raw are $110

nice jig. Same top plates as the blue jig. better sides.

actually been making these longer than the blue jig the side plates have press in pins so you don't have to remove that rear pin when milling like in the blue jig

be careful with jigs with out drill bushings.

remember the drill your pushing through the receiver and jig side plates is harder than the aluminum. so if your a little off it will make the hole in the jig larger this will then throw off your hammer and trigger pins and crazy stuff could start to happen with your lower. the kind of problems you read about here in the gun smithing section
