Your favorite 'value' BCG?

Another great option from PSA, Microbest:

I don't understand the question.

Forward Controls Designs NP3, Geissele Nano BCG, Cryptic Coatings or Triarc enhanced NP3. And LMT of course.

Hey fellers... I shoot lever rifles and bolt guns but I do have an M&P Sport II. I would like to acquire a spare, S&W factory BCG for this carbine. Don't need it, just want it as a spare, or to drop into the gun while I have the factory original bolt on the bench for cleaning maintenance.

Not looking for anything of any higher quality than what is already in the gun. Only things I've done to the gun besides shoot it is a better trigger, 45-degree ambi safety and some different furniture/featureless stock.

Thanks for your experienced advice.

Got some spring things from PA.

They sound pretty good to me...

"1. MPI tested Bolt MP4 (Individually tested)
2. HP tested Bolt (Individually tested)
3. Black extractor spring Insert
4. Crane O-ring
5. Shot peened Bolt
6. Chrome Lined Carrier
7. Chrome Lined Gas Key
8. Grade 8 Hardened bolts"

I'd just pickup that one from PSA or maybe a Toolcraft from PSA or whoever has them in stock... here's a chrome one at PK.

Thanks crufflers.

I took apart a nice reliable PSA NIBX BCG tonight and it looks like it had a normal spring, insert, and o-ring... replaced with a 5-coil, and new insert... no o-ring.

All BCM BCG's are HP tested; NOT all Toolcraft or AO Precision BCG's are HP tested (and some of their bolts come made with 9130 steel, as opposed to the stronger Carpenter 158).



BCM requires a better standard for their BCG (and test fires them first), and that's what I go with.

How about rubber city nitride bcg for $150?
