The M305 is a tinkerer's gun. The fit and finish is on the rough side. Even guys who love them call them "a diamond in the rough".
But for $500 it's a great cheap rifle to start on. You'll need/want to spend $200-$300 more and $50 for one of the M14 Clinics around. But it is well worth it.when you consider a basic M1A from Springfield Armory goes for about $1800 here.
I knew none of this when I bought my first one, and was very disappointed when I opened the box and cycled the stuck action.
I've since spent literally hours reading the Main Battle Rifle forum, viewed several youtube videos, got some input from some very knowledgeable people, and attended one of Barney's (aka: Tactical Teacher, aka Hungry) M14 Clinics.
I eventually came to love my ugly duckling rifle and actually bought another one which I also fixed up.
Some things I've done:
replaced the flash suppressor for Springfield Armory's (better quality, appearance, and properly angled) -- $100
replaced the front sight (with Springfield Armory's National Match) -- $35 or $50
replaced the rear sight assembly (from SPCAMNO here on this Forum. The ones he sourced have much better fit/finish and are able to hold their adjustments without shaking loose) -- $100
replaced the Operating Rod Return Spring Guide Rod -- aka: OpRod Guide (with the fluted round one from M14.ca instead of the original flat guide) for better consistency -- $50 after shipping
shimmed the gas cylinder so that the gas lock was properly tight at the 6:00 position (shims obtained from Barney)
properly indexed the barrel on the receiver (not possible for me without the help of Barney's work bench, barrel vice and 4' long breaker bar)
tighened the OpRod Guide on the barrel by peening the boss on the barrel to allow for a tight fit of the OpRod Guide (done at Tactical Teacher's M14 Clinic)
bought a Flash Suppressor Castle Nut removal wrench (I could NOT get the nut off without it) -- $25
thoroughly cleaned and greased the rifle properly
shot 100 rounds through it (the M305's need to be broken in by shooting them)
sanded down the sharp edges on the stock and the OpRod handle
I also bought an M14.ca Blackfeather RS aluminium stock ($640), a mil spec buffer tube for it ($25), an AR15 pistol grip and Magpul AFG (forgot how much I paid for them from Brownell's) and a Mission First Tactical butt stock ($160); also got an ARMS18 scope mount and ARMS22 QD rings
Very happy with my project now
