| I'm doing a budget build and was looking for a descent priced 5.45x39 bolt . Anyone point me in the right direction ? Thanks |

Just remember there are at least 2 different bolt specs, depending on whose barrel/extension you use.
The cheapest option is to open up a 5.45 bolt, is not hard to do (or have done). I would be sure to check headspace with whatever bolt is used with 5.45 builds, to be safe. Some bolts are just opened in diameter, some also are deeper (affecting headspace). The Ballistic advantage and Spikes bolts appear to be the same spec, Model1 sales use different spec bolts. |

What about extractor? 5.45 has much thicker rim than 5.56 Quoted:

Budget. open up a 5.56 bolt face to fit the 5.45. What about extractor? 5.45 has much thicker rim than 5.56 The bolts that I modified were for a Spikes and a BA upper. These are deeper (and opened up face diameter), so there was no modification needed on the extractor. I believe the other standard does require a different extractor or a modification to a 5.56 extractor, this is where testing will prove what works. If at all possible, use a matched bolt from the manufacturer of your upper (or barrel/extension). I modified a few bolts using my original Spikes 5.45 bolt as my model. The dimensional difference is not that great, but must be done carefully, since headspace is determined by the interface of the bolt face to the barrel extension. Again, if possible get bolt recommended to match your existing barrel. Who makes your barrel? I have one new AA bolt sitting in my spares, along with a couple modded bolts. The AA bolts are of the same standard as Spikes/BA. I really do not know who all uses what as their spec, but yours must be done right. At that point, you'll love your new rifle- they are a hoot to shoot. HTH
