Your XM7 deserves to shoot as well as it should, so treat it to the right parts.
The team at Bristol Based Airsoft (BBA) have put together the worlds first APFG XM7 specific hop-up nub. The amount of hop you can apply with the XM7 is an infamously narrow window. You have very little choice between how much or how little you can apply. This is particularly tough if you're power output is less than 1.5j and you intend on using 0.3g or heavier BBs.
This is a drop in replacement that swaps out the stock APFG XM7 nub. A one piece design. Combined with the Crimson Hop-Up bucking, you can expect really amazing performance (with heavy weight Warhead BBs).
This nub is aimed at improving the fine tuning ability of the XM7s hop-up.
