RCM HK MP5 Complete HK Style 9mm Bolt Group

This BCG is extremely well machined and produced a .015 bolt gap in my POF MP5. The only issue is that it states in the decay this carrier group will work with both semi or full auto guns but it definitely would not fit in my POF due to the rear compliance tab that is welded to the rear pin guide. Also, this BCG fits a little tighter than the factory POF price of of crap carrier.

Been using these in my builds and shooting subgun competiton with them. Never had an issue and pushing 8,000+ rounds on one unit alone

I couldn't swing buying a real SP5, or a replica. But I worked out that I could get all the necessary parts together on my budget. I was especially worried about the BCG, being the most expensive single component I needed, but the fit and finish is perfect, and it works with all the other parts.
