it's a British parts kit bult on a Buena Park Entreprise Aussie-cut receiver. Serial number is EAI 002062. The barrel & chamber are chrome lined and had some rust spots in the chamber but those came completely clean with a chamber brush. Receiver is billet forged and has a nice purple-brown patina on it :-/

Hunh, the first images I posted were too big so i deleted them and resized them using imgur message board size. Perhaps the larger images are not updated yet though they appear smaller to me. :redface:

Gas piston looks to be a bit too short. What'd you spend on your SLR?

Beautiful L1A1 with a very desirable Buena Park receiver.

Have not shot it yet; Chambers rounds from all four of my original inch mags; all click into place. Checked head space and it closes on the go gage but not the no go gage. I thought the gas iston looked a little short as well but it is original military gas piston; I imagine it shoots since the previous owner sold it to the shop after firing it and not cleaning it :( It had carbon all over the gas piston head and at first the piston would not come out when I removed the gas plug; after a good cleaninging of the tube, piston and spring it pops out now when I remove the gas plug. New spring and L1A1 gas piston otw just in case.

Well, I think that we found the problem from your other thread. Measure the gas piston that came with the rifle. It should be about 11 5/8" long. I would be curious to see a picture of the gas piston that came with the rifle.

Ok the gas tube had some back and forth play in it so I removed it and cleaned the threads, gas hole, end of tube and re-screwed in the gas tube to the gas block. No movement now. Replaced the pin that holds it in place, still no movement; hole is lined up without any back and forth wiggle. Cleaned out gas tube inside of it and there was some brown rust gunk. Now the new USA-made Falcon Arms piston and spring fits. the end of the gas piston is now just very slightly from the end hole in the receiver, not as far as before.

Painted end one on left in both photos. It is shorter for some reason but appears stock military gas piston ???? New, slightly longer one is in the rifle now. Just need to fire it.

:beer: Shootin time.

Cleaning the paint from the end of the rod, and whatever else dripped in around it may help with the fit.

September 10, 2017, 20:09
there should also be play in the gas tube. maybe not so much fore to aft, but it should roll a little left to right. It behaves as a shroud for the rod, not so much a containment vessel, needs to be able to expand when it heats up.

Roger, it wiggles side to side slightly. I am glad I took it apart as it needed cleaning badly. Nice red brown liquid rust residue was all over the threads and inside the tube and gas block; apparently its been sitting in the shop for a while. My spraying it down with clp removed a lot of surface rust and made a nice thin film. All clean now. Why was the gas piston, which the end is blued not painted, a surplus Brit gas piston, be shorter??

When the rifle is in battery you want the end of the gas piston to be slightly back from the bolt carrier.
If the rifle is out of spec you sometimes have to grind the receiver end of the gas piston to correct this. Your gas piston could be from such a rifle. I think Century made some short gas pistons also.

That's interesting. This rifle had obviously been fired with the shorter gas piston in use. I guess this would require more gas to properly cycle or maybe it was not cycling correctly every time so the former owner sold it to a shop. Hopefully it will function with the new gas piston and spring in it. It's slightly back, about an 1/16th of an inch from the hole in the receiver. With the original gas piston it was back 1/8 of an inch. The original short piston, with the receiver end dipped in blueing, is marked FN

First shots at gas setting 5; it came set at 6 but with a shortened gas piston. 20 shots from 30m standing. Keep in mind I am right handed but left eye dominant so I have to shut my left eye and typically shoot a little to the left on all my guns:

No malfunctions, no failures, ran like a champ. The last 6-7 were rapid fire also standing, 30m.

Second mag, standing, 25m. No rapid firing:


Only one failure; first round stove-piped; ran bolt and cleared it, ejected round that was halfway fed, inserted next round, no failures the rest of the magazine.

Your SLR is GTG.....now what will be your next riFAL and what is in the batter's box :whistling:

Next? You mean one is not enough?!

I'd like to get some more mags for it and a nice wood stock set.

Will try a couple of Moses mags next.

Hang out here for a year and see if you ask that question again.
I'm only quoting you for posterity :biggrin:

Oh yeah, and contact yellowhand about SLR wood or Dean or just watch the MP closely :cheers:

Nice rifle and shooting!

Tried a aluminum metric magazine I picked up for $10 at a lgs and it fit fine, locked up with a click. No wobble at all, feeds fine. looks to be a pre-ban aluminum para-mag. Wish he had more.
