This is how the PS90 should have been designed.

I just picked this up today after it was shipped to my FFL. It will be turned into a SBR as soon as possible.

Sight drops 1" (top of the FNH red dot sight base to the top of the rail)

Any difference in weight? Looks nice. Thanks for posting.

That's pretty awesome. Didn't have a clue anyone was making those. Would make a sweet SBR.

Sorry I can not really tell yet, it is striped and my other FNH P90 receiver is assembled. Thanks

This is the description of the mfg.

Precision CNC'd out of billet 6061 aluminum
*Weighs 14.8 oz (35% lighter than the Factory FN receiver)
*Tactical low profile, integral, 12 lug, mil-spec picatinny rail
*Monolithic single piece construction
*Billet 6061 aluminum construction provides higher strength than the factory cast receiver
*Durable type II anodized finish
*Marked 5.7x28
*Sight tower design allows enhanced magazine changes

Let us know how it works for you.

If you don't mind me asking, what is the cost on that receiver? (Send via PM if you don't want to post the price publicly... or just PM me a link if you would be so kind)

 

[jaflowers]

They were on GB for $359. Wish I seen/known about them prior to my SBR submission. Oh well, another time.

 

[SAVAGEJIM]

I saw these on GB also. I'm very tempted to hold off on some other upgrades to save the $450 to buy one ( $360 + $50 FFL transfer fee + S & H)

While it is unique and slick looking, I see that you have the ERT sling. Where do you attach the sling mount on the receiver? Also, any ability to add more rails? If you use the top one for optics, is there a way to mount other items on the receiver that is not shown?

Looks like it is a good beginning but I think that more work is needed to make it more viable to the masses.

The design goes all the way back to 2007 when Thompson Machine first came up with them. Didn't like it then and have not changed my mind. :biggrin:

that is my exact question for a forward sling mount.
Additionally, there are no provisions for side rail mounts.

The only option to address this is to get offset mounts that you use off the top rail

Just use the ERT and sling as a single point sling and you are good.

That's what I do. Now, I wasn't a fan of it in single point prior to SBRing my PS90, but now, it works very nicely.

That receiver is pretty slick, but I kind of like the "hand carved" cast of the factory version.

I like the lower rail position. So many optics are just a hair too high for me on my PS90.

Overall though, I'm not a fan of the aesthetic and the lack of side rails.

I hope you get many, many years of enjoyment out of it.

Defo. The lowered rail does make for better zeroing especially for helping the zero to remain true at shorter ranges.
At first, I wasn't a fan of the Thomson single rail, but after shooting my PS90 at 10 and 15 yards with it being zeroed at 100 yards, the lowered Thompson rail on the EFFEN90 looks like it will reduce the elevation discrepancy ant such shorter CQB ranges.

On my stock receiver, I will experiment with zeroing at 50 yards and 25 yards before shooting again at 10 and 15 yards

Nice!!! :shock:

Looks like you could install the front sling attachment point on that. Hard to tell from the angle of your picture with the mag in to see the clearance.

thinking more about this, yes, I agree. The aesthetics are lacking but the precision is there because it's CNC milled and its stronger.
My other dissent is how short the rail is.

But despite all this, I'm still going to save up and buy one.
The superior precision from the machine is aesthetics enough for me and the functions outway the lack of my gripe about the rail being too short.

 

[Copper&Black]

Finished it up, added a bolt on side rail made by the same people. Had to use a RMR mount with a rise to it to bring it to the perfect height.

Very nice setup!!!
