Yup Norinco M14s were" unfinished "when they hit the states.
Here is a " finished" version.......below. ( Built it to be a general/ all purpose rifle for close in to distances in excess of 500m.)
About the only thing left from China is its forged receiver and 1 piece oprod.
A few notes:
1. I had the connector lock converted, as I didn't want to use the popcycle method with an M14 synthetic stock. ( This is a year around hunting, hog eradication, rifle carbine course, 3 gun, RnG , DMR, shtf shootin stick that sees alot of use in all types of weather.
2. Synthetic stock is not bedded, as this is not a necasary item to get them to shoot well, provided the stock and handguard are properly fitted to the action. I filled in the selector lever hole, and replaced the M14 " flipper" but plate with another from an M1Garand. Cleaning kit fits inside buttstock where it belongs.
3. The bbl was made by CRiterion ( bought it thru LRB) . It is an 18.5 inch standard contour match quality, 1:10 twist chrome lined tube that shoots just as well now at 57000 documented rds as it did when first built.
4. Bolt = TRW along with trigger group. ( Headspace= 1.6325. TG worked up by Ron Smith ( Maxx2)
5. Sights: USGI M14 rear sight with std rear sight aperture and Smith Enterprise gas lock hooded ( HK style) front sight. ( Circle of doom in a reliable 7.62x51mm semiauto)
.062 front sight post adjustable for elevation instead of windage, and can it in the dark after another modification. )
6. Replaced the flash hider/ front sight assembly with a direct connect Vortex flash hider. ( Less overall parts, flash hider works well at what it's designed to do at 25 % more on average, and less overall length. ....Rifle is 39 inches overall .....which is less oal vs an M16A2 and a tad less than 1 lbs heavier vs same M16A2.
7. Gas system = SEI warfighter.
8. M14 sling that I utilize a bit different vs common folk.....lol.
9. Optics: After trying on several for size, I prefer the gen1 ARMS 18 split rail mount. Because China reverse engineered the fricken M14, thier receiver dimensions are a very close match to M14 service rifles. In short, optics mounts designed to properly fit the M14 will match up well with the chineese versions, including the Polytechs. I replaced the forward tension screw with a fro t sight set screw......as the latter fits flush with the mount, thus allowing one to remove the handguard without removing the tension screw at all.
Pics below show some close ups of this rifle and the other rifle in photo = my M1A A1 ( 1983 all TRW) Bush rifle after I sold the folder stock for a small fortune years ago and bought a truck load of GI synthetics, birch, and walnut stocks from " Freds ".
Note: M1A A1 sports the common SAI ( Wilson) non chrome lined 18in standard contour , 1:11 inch twist bbl. The current scout squad will have the same, and of the 20 or so I have fired or witnessed being fired, the scouts all shoot well.
