Weasel, BEFORE you shoot that rifle check the bolt gap.
Go to your local parts store and buy a "feeler gauge", if you don't already own one. Pull back all the way on the charging handle and let the bolt/carrier fly forward into "battery" on an empty chamber. Look up through the magwell and insert the feeler gauge between the bolt head and the bolt carrier. The acceptable range is .01-.05mm or .004"-.020", the closer to the larger numbers the better. Remember, the numbers get SMALLER as the bolt gap diminishes.
Do this BEFORE you shoot it. If the number is too small, it is not difficult at all to replace the rollers with "+" sized rollers to bring the bolt gap back into spec. All it takes is a small hammer and a small punch (or a skinny nail ground flat if you're a ghetto-smith like me) and new rollers available from good places like
RobertRTG parts.
If the bolt gap is out of spec, not only is it really hard on the gun, it can be dangerous to deadly.
PLEASE PLEASE PLEASE check the gap BEFORE you shoot it. At worst, you'll own a brand new $10 feeler gauge that you can use the next time you need to adjust the solid lifters on your racecar.
Oh yes, on my Century "Black Widow" CETME Sporter, I had to slightly reshape the front of the mag well with some hammer and punch work to get my G3 mags to seat and feed right. Yeah, it made a few ugly spots, but it works a ton better now.
BTW, that's some good looking wood on there! Have fun with it AFTER you check that bolt gap.
