I can buy either an oly or sendra for close to the same money. which would you buy and why?

The sendra has no auto markings, and also no other engravings to show who did the conversion Does not have any bushmaster markings on it (did sendra convert any of their own?) It is marked XM15a1

The oly is a Paws conversion, and has a lot nicer finish. Serial # starts with PO. It looks like it was stamped twice on the serial #

Do you know who did the conversion on the Sendra? Ask the seller.
All things being equal I'd much rather have a Sendra conversion than an Oly conversion...
What is the overall condition of them? Do you have pictures?

Also some of the conversions were marked in places that is no longer allowed...like under the grip....that might be why you don't see any other markings.

Don't have any pics. Honestly, the sendra looks like crap as it has multiple layers of paint on it. Also looks like it has some dings in the metal, but it could be scratches under the paint The owner doesn't know who converted it, and the Form 4 actually states Sendra as the mfg. I am guessing it was either "Vibra-penned" and the paint filled it in, or it is under the grip like you stated. If I bought it, I would probably have to have it refinished. It comes with two complete uppers.

The oly looks really good, It's not annodized. Looks like duracoat or something. Comes with 1 upper

Both guns run equally well.

I'd go with the sendra. Olys have a long history of having issues. Those issues can be fixed, so if a owner had the issues fixed, you could be fine. I'd still rather the sendra. Just because.

SOME Olympic receivers had dimensional issues, but I've never heard of a serious problem with the PAWS conversions. Mine has fit and fed with every upper I've put on it. They were professionally coverted and are as close to a factory M16 as you can get. I would buy the Oly without reservation, especially if you don't know the history on the Sendra.

the Sendra, aka Nesard, Drasen looks to be refinished. It's an early A1 style lower none of which were hard coated and had a purple cast to them. I purchased quite a few from them in that serial number range which is mid eighties. TG

That sendra looks about as good condition as any other sendra I've had. I wouldn't say its "beat" in any way, shape, or form. I'd stick to my first reply of buying the sendra.

The Olympic/PAWS lower is not necessarily a bad gun - but the Sendra lower is more likely to be in-spec than any unmodified Oly/PAWS (though not by a very wide margin).

No matter which route you choose, all can be made OK, eventually, with some smithing, if it turns out there were dimensional issues with either receiver, after the fact.

So, at this point, it's up to you, or some other bidder, to decide, if the Sendra/? is worth more than the Oly/PAWS.

+1. From the pix, they are basically equal. I would go for the Sendra.

Go for the Sendra I have one and it works great. My buddy has a PAW OLY and it needs to be put in spec.

buy the one that is cheaper by a huge amount of money. If they are both close in price buy the Sendra

10.5 for the Sendra, 10 on the PAWS Olympic

OK, the guy that owns the Sendra is a little flaky. I got less comfortable the more I talked to him about the conversion and requesting more detailed pics. I feel like he knows there is something wrong with it.

The Olympic mates up nice and snug to two different Bushmaster uppers. It also mates up to an Armalite upper, but the takedown pin is really tight. I think I is pretty close to being in spec.

Since I am more comfortable with the seller of the Olympic, I'm going with it.

Sounds like a good plan. When buying NFA, it's always time to listen to your gut.

BTW, when you get the Oly ... in addition to sometimes being out of spec, Oly used non-milspec takedown pins that often stacked tolerances against you. So before worrying about the lower itself, try swapping in a new, milspec rear takedown pin. You might even want to polish the heck outa it before installing. I've had tight-fitting Olys where that swap did the trick.

Have fun!

little off topic but..... does that same trick work for Semi Olys that were from the early 80's as well? i got a really early Pre-Ban lower that has a really tight take-down pin on it.

It should. The trick is to start with a new milspec pin, install and test; if it's still tight, polish the outside of the pin; sometimes radiusing the front edge helps, too.

If all of that fails, it's not a pin issue, it's that the hole for the pin is slightly off from where it should be. If so, you can always slightly open the hole in the upper, but usually that makes the upper fit too loosely on other lowers. The real solution then is to send it off to M60Joe; he can drill out the takedown pin holes and sleeve them with brass bushings that reposition the holes to spec. IMHO, the bushings route is preferable to welding up and redrilling, because welding on a 30-year-old hunk of aluminum gives me the willies.

1910 may put that in the early 80's,
my 4xxx was bought in late 84 or 85, and converted in 86

I 'll see if I can did up the number range and date of purchase,,,

I own two Sendras, 025xx and 090xx. Both have that famous purple anodizing hue, and both are very fine receivers.

If the OP didn't buy the sendra, he want to share where it is?

Mine is semi-purple. It runs like a champ.

in 04, when I asked what I should buy, 'Sendra' was the unanimous recommendation.

The Olympic looks fine. Go with it if you are more comfortable with that seller. My Frankford (Olympic) needed a minor tweek by M60Joe to fit uppers properly but runs great. I'm happy with it. I'm sure you'll be happy with your choice.
