MA legal AR pistol build may have just got a little easier

[7.62x39]

Making that 50oz weight limit for a MA legal AR pistol build is tough, but this will help. I wish they gave the weight of it though.
They put this baby on a serious diet.

[STRIKE=Any idea how much the fcg milling will remove on top of that?][/STRIKE]

12.1 OEM, 11.5 finished. .6 oz savings from stock lower.

Wait, it has to weigh a certain amount now too?

Yup because 51oz is more evil and killy than 50oz. lol

Love my AR pistol!

carbon fiber? https://www.tegraarms.com/products/ar-15-lower Seems like it should be strong, but don't know much about them. 3.65OZ though @ $80

That receiver is still raw. Look at it, there are no FCG/selector holes or trigger slot.

All the others mentioned in this thread are 100% receivers. No good for those of us who roll our own.

Uh. . . Ti weighs 60% more than Al.

I don't get this obsession with Ti.

A couple of years ago, Aeroprecision made a very cool precision lower as a one-off. Its not practical, but I'm sure it is very light.

AWB less than 50 oz.

 

[dcmdon]

Yes, and I think to have any chance of making it, you would need the lightest receiver possible. Probably all plastic.

If you had the change to spring for one of the ULTRAlight carbon wrapped barrels for $900, you could probably make due with Al. Too bad Proof Research doesn't make anything shorter than 14.5"

The ban era OA-93 made the weight with a skeletonized aluminum receiver, so it is doable

Not exactly new. Same as it was everywhere from 94 to 04. No AWB sunset in MA

48 oz.

Wait....so, I need to register it as an SBR and make sure it weights a certain amount?

I clicked the link and the first thing that came up was the "Buy It Now" button. Subliminal message?

Too bad you'd have to remove the hand guard to get around the the awb too.

pistols can violate the ma awb . It's for stuff like ar ak pistols , tech9 , mac's , Uzi etc.

It's easier to just sbr a ar in mass then build one to match the awb .

Either or.

When the mag is outside the grip.

48 oz.

To bad you can't even get that from a dealer in mass, it counts as a hand gun and I have a feeling it's not on the lists.... now if you can get one ftf it would be fun....

Mag Tactical makes a magnesium alloy lower that's under 6oz. The lower and upper are less than the weight of that skeletonized lower combined.

And their fully assembled pistol is 4# so unless there are magical tricks available, it isn't happening.

Depends, if you could find even lighter parts like a lighter rail, titanium BCG, maybe a lighter barrel..every ounce counts, but your probably right. 50 oz is 3.1 lbs, that's very skimpy.

Drop the hand guard . Can't have one on a ar pistol in mass. It counts as a barrel shroud.

Lighten the bcg. Can go ti, but you can Swiss cheese a semi bcg.
Slick slide upper.

Handguns/Pistols:
(C) a semiautomatic pistol that has an ability to accept a detachable magazine and has at least 2 of--
(i) an ammunition magazine that attaches to the pistol outside of the pistol grip;
(ii) a threaded barrel capable of accepting a barrel extender, flash suppressor, forward handgrip, or silencer;
(iii) a shroud that is attached to, or partially or completely encircles, the barrel and that permits the shooter to hold the firearm with the nontrigger hand without being burned;
(iv) a manufactured weight of 50 ounces or more when the pistol is unloaded; and
(v) a semiautomatic version of an automatic firearm; and

BCG is already lightened. Buffer is lightened.
Bottom line: You need to cut a full pound from a pistol the mfg created as a lightweight firearm.

If you remove the handguard what goes in its place?

ha ha, that's a heavy receiver, roll your own for third of the weight ...

Boris, is that plastic?
