After a six month wait, Brownell’s has finally received the SA Inc, NM unitized gas cylinders. Don’t waste your time and money. This is the second one that I have returned due to extreme poor quality. This is not Brownell’s fault but who ever is making them, be it Springfield or one of their contractors they are just plain junk. The screws are not centered in the spindle valve. The front band is not centered on the gas cylinder and the tabs are not bent properly. There is no excuse for this kind of work not to mention that the cylinder is now ruined. Wake up Springfield!!!

Get a welded one from Fulton Armory or send your gas cylinder and front band to Ted Brown to screw and glue. Either one won't dissapoint you with their quality.

For a top-notch AMU-style (screwed) unitizing, send it to Warbird.

Good prices, fast, and superior quality work.

Thanks flcracker.

I think I may have found a sollution for unitizing the SA Inc. gas cylinders.
In a week or 2 I'll know for sure. Price will be just a tad more but worth it.

I did come up with a better idea for unitizing the front band which will leave the gas cylinder in the (as is USGI configuration) unmodified condition allowing the spindle valve to turn.

It works best on match barrels and I'm redesigning it for use on USGI contour barrels. I'll let everyone know when everything is done and I do some shooting with the new design.

A jig will be required.
Cost will be more so I'm trying to figure out a fair price.
That's what I like about working on these rifles. Something can always be done better and a little different. In this case, the spindle valve remains unmodified. Also, if you need to change the gas cylinder down the road, you can. Just like a standard rifle.

My late father was a machinist and tool maker for over forty years so I tend to be picky about machinework details like this. It is hard to imagine that the people doing this work do not have templates for locating the holes or a jig consisting of a barrel spline section to force the band and cylinder into alignment. The work in the picture is pure crap that looks like the work of some drooling idiot with a hand drill.

Do the screws go all the way through the spindle valve and out the other side of the body?

The screw holes do not go through.

It doesn't really matter who did the work, they just need to find a new career that has nothing to do with pride, quality, and craftsmanship. I find it hard to believe that Springfield Armory would ever accept such work. Maybe they are rejects they sold to Brownells and the management doesn't know any better. The spindle valve is hardened and not easy to drill through without the proper know-how, necessary skill and equipment. But why would someone butcher a job like this and expect to get away with it...........is beyond me. While the gas cylinder looks serviceable, who would ever want to use one like this, and it's supposed to be an up grade to National Match!

I ordered one of these last November and it was flawless. Ordered a second one in March but they were out of stock, so it was backordered.

The backorder finally arrived and it is in the exact same condition as the one in your photos. I had to file down the overlapping band just so it would go on the barrel otherwise it would NOT go on. The screws are offset like yours and the tabs for the handguard are bent upwards like yours. I had to bend them down just so the handguard would go on. In spite of my having to do this work, the barrel band is off center, I have to use shims to get the gas cylinder lock to time, and the gas piston feels loose in the cylinder - too loose. This leads be to believe that the gas cylinder is well used. I had already planned on sending it back due to the poor quality but had to jump in and confirm your experience - you are not alone.

I know for an absolute fact that Springfield makes these for Brownells becasue I talked to both companies at length about it at the beginning of this year. The backorder (at Brownells and Springfield) lasted from March until now. Either Springfield sent "blems" to Brownells, or perhaps the QC at Springfield is so bad that they both are selling inferior products. To Brownells defense, they are not M14 specialists so they may not be aware (yet) of the bad quality.

I had a similar horrible experience with my M1A at the beginning of this year which led to Springfield having to replace my entire rifle. I am starting to wonder about Springfield Armory. I hope the "Lifetime Warranty" does not mean a lifetime of returns/repairs/replacements.

Geez guys.
Everybody knows (or so I thought) the tabs on the band are supposed to be bent for a reason.
The handgaurd is "always fitted" to a unitized gas cylinder.

I have to admit the workmanship is really poor.
Just send it back and Frank will refund your money.
Well, he won't refund your money if you do something else to mess it up or make alterations.

Warbird,

Yes, I am aware that the tabs need to bent upwards to custom fit the handguard. I have a couple of unitized cylinders from Smith Enterprises and the tabs are not nearly as bent as on this recent one from Brownells. Mine were bent nearly all the way up.

Regarding my return of the item after I "modified it" it seems that the loose gas piston problem was due to a very worn piston. So, after installing a new piston, all is well. I will keep this cylinder afterall.

Unitizing the gas cylinder will not preclude this step. As far as the screws go, it looks like they are hand laying out and drilling the location rather than using a fixture as they should (or they have a piss-poor fixture). It does look like crap, but still functional. I might consider keeping and trying it, if it was free.
