I have the MI URR and it is awesome, but it was almost $100.
All the times I have used Botach they have been fine, but not always for others.

I may be looking at it wrong, but from the photos, it seems to lack the vertical spine that stabilizes the upper receiver.
If so, it’s not a good substitute for the MI URR. IMHO, anyway.
Yes, I consider the URR to be superior, and the removeable fin is a nice feature, but I think I remember paying $95 for mine. Most of the other offerings only support the extension.Originally Posted by Dave J
I have the BOTACH/KZ barrel spline. Bought it several years ago and was hounded for not buying a 'G' Reaction Rod at double + the price.
By the same token I also have an item listed on the bottom of the page the OP linked to, the KZ AR15/M4 Receiver Extension Buffer Tube Block, which is also substantially less than the 'G' Reaction Block® AR15/M4 Mil-Spec Buffer Tube ($60.00 vs, $200.00)
KZ: https://botach.com/kz-ar15-m4-receiv...er-tube-block/
G: https://geissele.com/reaction-block-...tube-only.html
But then, I also use Toolcraft BCG's versus the latest and greatest from whomever.
