I can tell you 100% for a fact, through feel and through pictures that LRB and Bula receivers have far superior machining and finishing than a SAI receivers. That doesn't mean they are of poor quality, but people go ape-chit over the cast vs forged debate, so it matters to some people. Most of Fulton Armory branded parts are cast as well. Since the early days of SAI, there have been at least four different casting suppliers with the latest rumored to have its origins in Canada.
Most of the SAI parts or castings come from outside the US and are either finish-machined or finish assembled in the US. If you set the front sight to mechanical zero, left windage would have to be applied to the rear sight to achieve zero. There was a time when, and maybe still, that if you set the rear sight to mechanical zero windage, that the front sight had to be set all the way to the right and almost overhanging the front sight dovetail to achieve zero at 100 yards. They will also make sure barres are timed just right which means that to zero the rifle, the iron sights will be set closer to mechanical zero to achieve an actual zero. My most accurate M14 is built on a LRB receiver with a heavy Lothar Walther barrel (~1/2 MOA).Ī custom gunsmith will make sure operating rod guides are tight and aligned properly. The SOCOM I built is on a Bula receiver with a Criterion barrel. I've built three rifles on LRB receivers and three rifles on Bula receivers. There are now forged receivers available from LRB and Bula Defense, but LRB bas been at it longer and seems to be slightly more refined than the Bula. Shooting Sight makes fully adjustable trigger that is amazing! An annoyance, but the M1 Garand is identical and a quality hammer and trigger can be easily solved by a drop-in Garand hammer set. We do hear reports of broken hammer hooks and sears from time to tome. My preferred barrels are Lothar-Walther, Kreiger and Criterion. I've seen them shoot very well, but the copper fouling will build up quicker. SAI barrels can be pretty heavy on the tooling marks. If you go with a custom build, you get to pick which barrel you want. While it solves the bolt disassembly issue, it makes it nearly impossible to disassemble the bolt without destroying the extractor spring plunger. To fix the issue, SAI simply made the dimple for the extractor spring plunger much deeper. Sometimes, the case feeding from the next round will push up on the extractor and it will disassemble itself while firing. When Springfield Armory began making their own extractors, the relief cutout is there, but the extractor dog-leg was too long. This stopped M14 bolts from disassembling itself. To correct this, a M14 specific extractor was designed with a relief cutout on the bottom claw of the extractor. When the extractor is removed, the bolt guts fall out.
For anyone that owns a M14/M1A, they know that the extractor is what keeps the whole bolt together. What they did not know was that when using 7.62 NATO blanks for training, with a longer nose than a real round, caused the case-head to feed differently and it would lift the extractor out of place. In the early days of the M14, they used M1 Garand extractors. The bolt disassembling itself goes back to the early days of the M14, but for different reasons. To their credit, over the years, SAI has addressed most of the issues. That was back in 2007 and I had been reading about problems people had with over-indexed barrels, broken hammers, bolt roller impact defect, loose operating rod guides, bolts that would disassemble themselves while firing (not that common, but common enough that people had heard of it happening) and also the fact that Springfield Armory Inc had run out of GI parts and had been using cast operating rods, trigger groups, gas cylinders and flash suppressors. I wanted to own the most accurate and reliable M1A I could, so I joined the M14 forum (of which I'm now a moderator) and started learning as much as I could about M14's. I drooled over the M1A super match and I wanted one that was really accurate. Interested in the answer also, been looking at a Scout vs an entry level AR-10īefore I owned my first M14, I didn't know I'd eventually own six of them. Honest question.how much benefit would the extra to build one get me over say, a Springfield M1A Scout?
